Outboard Motor Question, HELP

29 posts in this topic

I'm looking for some feedback from someone out there that is an outboard motor mechanic.

Here's my problem;

Last fall on my last fishing trip my 1984 Johnson 60 HP motor bogged out like I ran out of gas, so I switched tanks, got it started and took off again. About 1/2 mile farther across the lake it bogged out again. I checked the tanks, both had gas and the vent valve was open. The motor would start up again as soon as I would get it stopped and put it back into neutral. I fished the rest of the day but I could only run the motor at 1/2 speed.

I took it to my mechanic last night and explained what was going on to him, he said "That doesn't sound good, it sounds like you are seizing up the motor", I questioned why it would re-start and run at 1/2 throttle, his answer was, " it doesn't get too hot at 1/2 throttle". He also told me if that is what's wrong with it, he will not re-build it for me, he suggests I get a new motor. Does this sound right? I left it with him so he could check the compression to see if the cylinder walls are scored.

Please if there are any mechanics out there I'd really like to hear your opinions, because right now I can't afford a new motor.

I would guess water in the gas, dirty carb. plugged fuel filter or fuel pump needs new diaphrams. Do it yourself or bring it to a bring it to a differnt shop.
Start with the filter and drain the gas along long with a new spark plug and try it. If that doent do it clean and rebuild the carb and pump.
If it was overheating it wouldnt start back up till it cooled down and it wouldnt take long to cook the engine if it was running like that.

I'm not a mechanic, but I had a problem similar to that years back. First, try a new hose from the tank to the motor, sometimes those connections can go bad. Hope that fixes it.

Is this motor a VRO (oil injection system) or pre-mix? Reason I ask is there were issues with the VRO systems back around '84-'86 or something like that. Not enough oil can give you these symtoms, if not seize the motor.

If your motor is pre-mix oil/gas 50:1 make sure the oil is mixed properly. I had very, very similiar issues as you once with a '88 40 Johnson. There is a sensor (at least in my old motor) that detects proper oil mixture. Mine was very sensitive if there was not enough oil w/ gas the engine ran like yours.

I agree with the hose/bulb idea too. Have had that problem too. Simple fix.

Carbs may be gunked up, I guess it could be several issues w/ the carbs. A mechanic will have to fix that if you're not familiar with it.

Rod Holder good point.
Check all the hoses and the squeeze bulb too.

Thanks for all thge replies. To answer several questions, it is not a VRO, I mix the gas, I also have always added a little bit more oil than is called for in a 50:1 ratio, I also had the lower unit seal change 3 years ago and had a new impeller put in so the water flow has always been real good. I put a new gas line hose on last year, I guess it could have gone bad in one season, and I checked the fuel filter and that was fine. I'm guessing (HOPING) that the fuel pump is shot and it's not a cylinder problem. I'll let everyone know when I find out.

Thanks

It sounds like you may just be fouling the spark plugs. try new plugs as well

Im no mech either but I have a friend that has a sim motor, his was VRO converted back to mix yer own, his acted up just as yours and it turned out to be the sensor that detects overheating. its worth checking anyway.

I am by no means a mechanic nor do I claim to know anything about outboards, but a friend of mine had this same thing happen to his motor last summer. He has an OMC that is about that same age (I believe OMC built Johnson or vice versa around that time). He needed to have his motor rebuilt and it cost him a couple of grand to have it done. His motor was doing the same thing that yours was and it was attributed to a faulty oil pump. Appearantly they had big time problems with the oil pumps around that time.

Like I said, I am no mechanic, but like the other guys said start simple (hoses, etc.) and work from there. DO NOT use the motor until you figure out the problem as it will mess things up even more!

I like the fuel system diagnosis as well, fuel pump, hoses. I also had a somewhat similar problem, and found that the coils were very weak, and there was a problem with the cd box. Not that that is the problem here however. I would not trust that the motor is junk, unless it has already been bored out, and is very roughed up. I would certainly try the easy things yourself before bringing it in.

Do the compression test. It's easy and inexpensive. You should probably have about 120 psi per cylinder, with no more than 10% variation between cylinders. If you have good compression, then you know for sure that the problem is related to either fuel delivery or spark. But if you have a cylinder with poor compression, like 60 psi, then you'll have to judge the value of the motor against the cost of repairs and what you can sell the lower unit and prop for.

I have a friend who has a 70's vintage 110hp Chrysler that had the same problem. He replaced the fuel pump diaphrams, still no luck. Then he took the carbs off and took them apart and soaked them in strait high octane gasoline for a week. He them used compressed air to blow out all of the jets and put them back together and put them back on the engine and it was as good as new. I hope this works for you.

UPDATE on motor problem,

Well last night I talked to my mechanic and he had some good news, the compression was 160# on cyl. #1 and 159# on #2. So now it should be down to some problem with the fuel system, definitely cheaper!!! YEAH!!!

I'd like to thank everyone for their input.

Ole1855 Your mechanic should have looked into a fuel problem from the very beginning.
This guy is either boning you or is inexperienced. Either way he's on the clock and your paying the bill. Find a different shop.

I had a similar problem with my 1974 10 horse merc. The problem was bad points. Fairly inexpensive to install new points, now runs like a charm. Best of luck!!!

I would not say that it is wrong to check compression. If it has bad compress., the motor will not work correctly. This is a good first step, as opposed to paying him to check fuel systems, hoses, and everything else, only to have a blown motor. Or the cost of a new this and that, to find that the motor is no good. ONce they put the parts on, they are YOURS! If you have not seen a compression test performed, it takes just a matter of minutes. It sounds like this may be a friend of his that is doing it on the side or something, or they would already have it running.

"That doesn't sound good, it sounds like you are seizing up the motor" Thats the quote from the mechanic.
A mechanic is like a Dr. You look at the symptoms and make a diagnosis.
Any shop charging 70 bucks an hour better have a mechanic that can make a correct diagnosis 95% of the time. When you've experienced most the problems out there related to engines its a no brainier.
Will this mechanic get this motor working right? Im sure eventualy. Tick-Tock

surface tension, i would say that the mechanic was right with his initial procedure. I would say that he was very lackiing in what he said. Telling someone that their motor is blown up and not fixable is a heart stopper. I have talked with several places, and guess what their first thing to do is when a motor isnt running right? Check compression. You can not properly adjust a motor that has bad compression. Call around and ask for yourself. I would wonder however, why he would stop? Go ahead and find the problem. It may have been a friend doing a favor for him, if not, probably pay for a whole hour, or amount anyway, should have done more.

Maxx he said mechanic and 70 bucks an hour.
Hey if he has a buddy looking at it then how could anyone complain if it takes him a while to figure it out.

Final update on motor problem.
The problem ended up being located in the throttle controls, when you push the shift/throttle lever all the way to full throttle, there are two wires that were getting pinched and would short out causing the motor to die, and when you brought it back to neutral they wouldn't touch allowing the motor to re-start.

Surface Tension, when you mentioned the $70/hr. rate, you were the first person to bring that up, not me, besides his rate is less than that. He is by no means cheap, but not $70/hr.

Ole1855, this is one of the best reasons I have seen to use a professional mechanic. You got almost 20 responses and had you done all of the things suggested you would have many hours of your time and many hundreds of dollars invested only to end up with the same problem. I think it is great that you had so much help with your problem but the fact remains that a professional will find and fix only the problem. This will save you money in the long run. Granted not every mechanic is good, but a good one will save you money in the long run. grin.gif

Yeah, but kwkfsh, he wanted "feedback". We are not actually there with the motor in our face to find the problem first hand. wink.gif

The key is if you don't have confidence fixing it yourself and trouble shooting, pay a good mechanic.

I realize he wanted feedback and he got great feedback. the problem is that all of us with myself included are giving feedback from a somewhat limited base of knowledge. Whereas a marine mechanic has been schooled and factory trained( hopefully ) and has an experience based knowledge that far exceeds ours. Many times it is cheaper to pay this person $70 an hour to fix it than it is to do it ourselves

Surface, I my post I said he got great feedback, I don't see how that is a slam. When I talked about a limited base of knowledge I stated "myself included". So if I slammed anyone I slammed myself as well. I have listened to many people complain about the rates marine mechanics charge and then spend weeks or more of valuable fishing time trying to save a couple of bucks. I firmly believe that if you cannot figure it out quickly it is best to take it to a pro. My input was designed to save people time and money and aggravation. I do not know how you come up with my attitude sucks. I think maybe you should reread the posts again. I have never seen you react so venomously before, so I assume you are just having a bad day. grin.gif

Look in the tank with a small flashlight. If there is water in the gas you will see globs of it rolling around on the bottom. Helps to be in a dark garage.

Don't smoke while you do this.

    • Way to go team!! I sure took the avg score down with my jake
    • nice story, fishing has a way of easing the pains we have. even when we hurt like crazy when done for the day we are looking forward to the next outing.
    • way to go, guys yep, the toms not about to give up even though its close to closing time have seen several strutters the past couple weeks and heard gobbles yesterday while fishing
    • great job. makes it 5 for 5 for team 5 congrats on a nice tom, 57 and that willl give our team score a boost
    • One More Cast      Photo by:  Roger Abraham   If any of you out there are regular readers of my tales, you have followed my recent struggles with back and knees.  I can’t put a name to this drive I have to be on the stream as of late.  It borders on obsession. I guess in my mind if I am healthy enough to fish the world is right with me and I am not getting old and feeble.      Today I was a witness to that I am not the only one.  Lots of anglers and hunters live to go out into the outdoors. .  It is what drives them.  It makes them feel alive.  It is their passion.  I told my fishing buddy Abe today my thoughts.  I told him how I was feeling a little old.  I guess my 60th birthday coming up next month makes me feel mortal.  Abe laughed and said I was a young buck compared to him.  Abe turns 76 this year.     Abe told me tales about catching big trout in tiny streams in Wisconsin and out west.  The twinkle in his eye when he reminisced I had seen before in many trout anglers.      We fished a stretch for 2 hours.  I sat down and rested often.  Abe kept on fishing. He got hung up in a box elder branch and lost a lure.  Abe told me box elders trees were his nemesis when he fished.   He asked me which tree was my kryptonite.  I told him, "ones with branches."  We both had a chuckle and continued fishing.   I thought to myself this guy is really driven.  I hope I am like him at 76.     We got to the vehicle and Abe wanted to continue fishing.  Abe’s waders sprang a leak earlier and he fell in the water a couple times.  He was quite wet.  He wanted to change in to dry clothes before we continue.  Abe peeled off his wet shirt and there were two things stuck to his chest.  He could tell by my questioning look he needed to tell me what was up.     Abe told me he had been having heart problems lately and he was supposed to be wearing a heart monitor.  He left it in the car because he was afraid of getting the electronics wet.  Here I have been whining about being old and the guy I was fishing with left his heart monitor in his vehicle.      Abe reassured me that he was in no danger and he could continue fishing.  I started brainstorming on a place to fish where it was not so hard walking.  Now that I knew he was not as healthy as he looked I wanted an easy place to fish.  I knew the place and it was upstream 5 miles.     We arrived at the well manicured field.  It looked like a golf green.  I picked the area because the farmer kept sheep and goats on the land and the weeds and brush were gone because of the goats.  We walked and fished.     Abe told tales of the old days and of fish lost and landed.  I walked a little forward to fish and looked back to check up on Abe.  What I saw when I looked back scared me and I immediately asked Abe if he was ok.  Abe was laying flat on the ground face down.  I thought the worst and he could tell by my face.  He told me to calm down.  His back was acting up and he needed to straight it out and that was the best way to do it.   We fished a little bit more and he took a photo of me.  He liked the lighting. He told me it captured the essence of trout fishing.  He did not have a camera.  I let him use mine.  He was not camera savvy and needed an impromptu lesson on how to use it.   We drove to his car and we talked about our love of the outdoors. We shook hands and headed our separate ways and promised to fish again soon.  As I drove home I smiled and thought about how I am going to be when I am 76.  I hope I am like Abe and my eyes still twinkle when I talk of chasing trout and I am still driven to make one more cast.
    • The past week has had me having multiple close calls and missing a brute at 45 yards.  Tonight I talked my dad to give it another try and there were birds in the field when we got there.  Birds ended up leaving as we tried to sneak in.  A short 20 minutes later they were back and we watched and worked the big group of toms and hens for more than 2 hours before we got one to commit.  Dad shot him with his 20 gauge at 48 yards,(this thing shoots an awesome pattern).  The 3 year old was down and only flopped a few times.   Nice 1+ inch spurs, 10" beard and heavy.  A good evening for sure!
    • Sorry to disappoint guys, but this tom was not my first bird of the season. Apparently that's part of the rules. The score won't count towards the team. I don't have any measurements for the jake I shot so we will have a zero from me.    At least my freezer is full. 
    • Way to  go 1957 !! Congrats!!
