Lower Unit Issue

13 posts in this topic

Here is my question up front followed by the story of how I got to this point.

Question: With the lower unit off and the shift in neutral should the drive shaft turn smoothly? When I turn the upper drive shaft (the one that connects to the motor head) it feels rough but I'm not sure if this is normal. The output shaft turns smoothly.

The Long Story:

Put the boat in on Saturday morning to do a little fishing on the St Croix and when I started the motor the starter gear did not release from the fly wheel. Turned it of and tried starting a couple more time hoping that it would free it self, no such luck. Loaded back on the trailer and headed home to start tearing it apart. Outboard manufacturers sure can pack a lot in a little space. After getting it apart and seeing that the pinion assembly had to be replaced I called some dealers and nobody had the part I needed on hand. I ordered the part and since the motor would be out of commission for a few days I decided that it was time to put in the water pump that I a purchased a few weeks ago. The water pump was sitting on a shelf just waiting for such an opportunity. When I drained the lower unit oil it was a nice creamy color so it was obvious that the seals needed to be replaced along with replacing the water pump. Went back in the house and put in another order for a lower unit seal kit. Now it looks like I will need to put in another order for bearings.

One more question: Are there any special tools I will need to replace the bearings?

Oh yeah, I guess more details and less story would be helpful.

1996, Evinrude 150, model number L150GLEDC

I've had to do quite a lot of work on my 70 Johnson lower unit. They are different, I realize. Boatfixer is correct, you are prolly just feeling the gears meshing.

As far as special tools go, a service manual is worth it's weight in gold. Sounds like you know how to work a wrench, but the manual will let you in on stuff you may not know about, like clearances and shims and that kind of stuff. For me, it was the best 30 bucks I put into my boat motor.

Great idea Boilerguy. Where do you have to go to pick up an Evinrude manual? Do the repair shops carry manuals? I checked the Evinrude web site but it refered me to the "Ken Cook Company" for repair manuals but that web site did not list anything for my specific model.

I picked mine off the internet. Check out HSOList or go to any decent search engine and you can get good info.

FunFish, I happen to have an Evinrude service manual that I could e-mail to you if you give me your e-mail addy. It is in pdf form for Adobe Acrobat and is a large file (104,700kb).

Thanks but I'm not sure that the copyright would allow that. I have a full shop manual on order. Just out of curosity who is the author, Evinrude, Clymer... The reviews I read on-line were not very positive for the Clymer manuals.

It is the Evinrude manual. I believe it covers motors from 92 to 96. I bought it as a download on HSOList. It would be easier to use if I printed the whole thing out, I just don't feel up to the task as it is over 400 pages. I'm no expert but I don't believe it would be a copyright issue since I'm not offering it for commercial sale, and only for personal use. Take care.

Sounds like I ordered the hardcopy of the same manual. Could you send me the PDF dale.rueber@embarqmail.com please while I'm waiting for my maual to arrive? I need more reading material. Thanks.

Sorry FunFish, I tried to e-mail it and I can't send a file that big. Never tried before so I didn't know there were limits. I would burn a copy and mail it to you but you would already have yours by then.

Thanks for trying, I got my hardcopy yesterday and the seal kit for the lower unit. I finished the seals on the top and water pump. Now I have to get a wheel puller to finish the output shaft seals. I'm still waiting to get the starter pinion in the mail. The manual has proven to be worth the price already.

If I don't get back out fishing soon I will be begging for somebody to take me along. Last Sunday after I ordered the parts I grabbed a rod and tackle, headed to St Croix Bluffs and did a little shore fishing. I may have to go again so that I don't get any withdrawals. It was fun but not quite the same as sitting in the boat relaxing and fishing.

    • We live in some sort of Bizarro world now - Sarah Palin calling Trump sinfully stupid.     Here's another one from Ann Coulter, who literally wrote a book "In Trump We Trust"    
    • You do realize that if the taxes were done that way, the cities would get $2.53 billion richer, and rural areas would get $2.53 billion poorer. The 7 county metro pays substantially more taxes (nearly 2/3 of the states total) than the other 80 counties in Minnesota combined, but only receives roughly half of the state expenditures.   Sorry to break it to you, but rural America is not fiscally solvent. Those citiots you speak of are bankrolling the entire country. It's easy to see on this chart: more urban states are to the left (givers) and more rural states are to the right (takers).  
    • I tried to purchase the screws yetti uses from Fastenal who is their vendor for the screws. They are only sold in large reels designed for a self loading screwgun. I finally called Casey at Glacial lake docks where I purchased my yetti and he sent me out the amount I needed. They work great to add additional fir strips. The plastic used to tie them together comes right off as you screw them in. Hope that helps. 
    • Sorry...was wrong on the specs.   Manufacturer is Core Ice.  It was 1450# for a 12' and 1250# for a 8'.  
    • I believe you want to use a zinc coated or galvanized steel according to the charts.  I'm sure someone will come along to correct me
    • In the back room there is a company that is using bonded foam panels (similar to garage door panels, but really clean looking), and had weights of 1250# for a 12' and 1450# for a 16'.  Aluminum trailer frames that could convert to a skid frame.  Can't recall the name.  I'm sure they were spendy, but I can see a concept like that going somewhere for the hardcore fishing crowd.   Yetti, Firebrand, Big Bite, and Glacier all had really nice display models.      Lots of campers (disguised as fish houses) out there at prices that make me want to jump into the business.  I was in two different manufacturers houses with prices well over $30k that had wire nuts for connections.  That is going to be a fun adventure for someone 2-3 years down the road when they find out their manufacturer saved $15 on their wiring.           
    • Thank you for all the help!  Ended up going with the Marcum VS485C.  After some research, there were a few other Marcums that were on the list (825 & 625), the Aqua Vu HD, and the Pan Cam.  The mini cams from all manufactures weren't what I was looking for, but they are cool and do have their place.     After seeing everything in person, I think the Aqua Vu HD had the best camera/screen.  The Marcums were a little bit behind, but the 825, 625, 485, and Pan Cam had similar real life clarity.  The 485 won out because of the $300 price point vs the others at $450-700, and was almost identical for resolution, other than the HD.
      I honestly think these cameras are all about 5+ years behind in technology in comparison to the broader camera/tv screen market.  Running off a 7-9ah battery is probably one of the limiting factors.  Another may be the cold.  The main reason (IMO) is that the manufacturers are hoping they can incrementally rape us by trickling out technology each year, similar to the computer manufacturers of the 90s/early 2000's.  For the price of a middle of the road underwater camera, I can buy a Chinese made 50" TV (these all have Chinese made 5-8" screens) and a GoPro or Sony Action Cam (which is 10x's the picture quality).
