sounds like an overheat alarm and your motor when into "limp" mode.

It could be a number of things. I guess the first thing I would do is a compression test.

[bhs91]

A compression test??? Sounds like something that a "certified" Yamaha dealer needs to do!!! Chances of me being able to fish on Mille Lacs on Tuesday????? Slim and none That sounds logical, when I reached down to pull the weeds off my lower unit after the alarm went off, the shaft felt warm, but then again i am not in the habit of feeling for a temp on that part of my motor. --it Monday can't come quick enough. Do I have to take it to the place that I bought it because of the warranty or can I take it to the guy that I normally take my small engines???

[Valv]

If you had weeds on water pickup grille you might have overheated it.....I really hope not.

Anyway you want to take it to a certified Yamaha dealer if it's in warranty, in case there's any repair to do.

You can take your chances on Tuesday, but if it's "cooked" you won't go very far.

[gunflint]

I wonder if the oil being low is a clue?

[bhs91]

Where is the water pick-up grille? I was under the assumption that if water was coming out the side, you were good to go. Anyway, I 'll bring it in tomorrow and see what they say.

[Valv]

It's on both sides of lower unit, approx 1" wide x 3" tall, plastic grilles, you can see through the other side.

I am not saying that's what it is, I hope not really, but you mentioned you stopped and removed weeds from lower unit, so I assume this could have been an issue, which you don't want to deal with since if it's overheated warranty will be voided and you will not get it fixed free of charges. I don't wish this to anybody....

Chances are a sensor or something simple happened and they'll get you going with no hassles at all, but have a dealer check it due to warranty issues.

[bhs91]

After reading your post, I went to check them and they looked clear. But, here's a question for ya'...If by overheating, you void the warranty and the only way to know if it is overheating is to hear the alarm, how can you be responsible for that?

Thanks for you help.

I dont know if this helps but I used to have a 30 hp yamaha (great motor) and I had to keep the oil resovoir over half full or the alarm would go off when it got down that far or it would go into limp mode like you are talking about

Actually I think it's designed so that the alarm will come on and go into "limp" mode (reduced RPM) before any damage is done. So as long as everything was working right, my thought is that you should be OK.

I am not judging or blaming you for anything, I am just trying to get an idea of what could be wrong with is from your description, and give you some information, I rather be a little scary and find out it is a small deal than tell you it's nothing and you'll have to spend $ 5,000 to rebuild motor.

I am not a dealer and/or affiliated with Yamaha, you have to ask the questions to them.

[bhs91]

My fault, I didn't mean to put you on the defensive. I really appreciate the ideas that you gave me and was just wondering about the voided warranty.

Again, thanks for the help.

1st off, weeds on the lower unit indicates impaired water intake for engine cooling. That's your 1st clue.

The water coming out the tube below the cowling housing is a tell tale hole. It does NOT indicate by any means that you are receiving a full flow of water through the cooling jackets.

The engine bogged; it went into safe mode do to not enough water intake. No biggie in my opinion as long as debris didn't get sucked into your impeller, or your impeller ran too dry....

I'm thinking it's probably ok....

But don't take my word for it.

[bhs91]

So I get my boat back from the place that I bought it and, as is the classic case, they ran it, no alarm, nothing for them. So I guess I run it normal and wait for the alarm to go off when I am on 7 mile by myself?? Also, if I took it in and they did not find anything, but I run it after this; does this void the warranty?

Thanks,

BHS

I'd say you're all right to run it and covered by warranty, within reason. If you run it again and the alarm goes off and you continue to ignore it then, depending on what your motor has for data logging capability (which I don't think is much in this case) you could be out of luck on the warranty.

What kind of testing did the dealer do? Did they actually run it on the lake for a while, or just on a hose?

marine_man

[bhs91]

They just ran it on the hose, as for the specific testing I am not sure. When I bring it in for this type of thing is it OK for me to ask? My fear is that by being too pushy and nosey, i risk [PoorWordUsage]ing them off.

10-4 on running it in within reason.

You have to ask the same question top the dealer, if they think it's fine you are off the hook, but be sure they write it down on the receipt for the service work, not just a labor charge.

Usually they add notes like "Customer reports alarm going off, concerned about overheating", then after work is done, they will add things like " Tested motor no overheating alarms and/or failure found"

Concerning the risk of "[PoorWordUsage]ing them off" I wouldn't worry, if I had to spend several thousands of $$$ on a rig I will demand good service, or the motor comes off my transom and back to where it was purchased.

[marine_man]

I agree with what Valv said...

I'm a little suprised the only ran it on the hose... with the hose you're forcing water into the water pump and the water inlet and you'd be less likely to see a overheating situation at low idle due to that vs putting the motor in a drum, lake, etc and allowing the motor to suck the water in... that's where you'd notice a weak water pump...

If it were me I'd call the dealer and explain your concern a little better - ie - that you have a weak water pump and that testing it on the hose probably isn't sufficient.

If they disagree tell them that you'll be down to pick up a signed statement (on the work order, etc) that they are satisfied that the motor and waterpump are in good working condition.

I've got a '93 Yamaha Pro60. Exact same thing happened to me and IT WAS WEEDS. It doesn't take much. It started dying off like it was running out of gas and then the alarm went off. I shut it down, trimmed it up and trimmed it down as fas as I could and it still took two minutes for the alarm to quit. Annoying - yes. But I'd rather have than than a warped head I guess. BTW - There was water peeing out the entire time. Now I just have other issues - on another post. Hope this is a little reassuring.

[bhs91]

This is reassuring, Thanks!! I am going to try it out today and we'll see what happens. I read your other post, best of luck.

Thanks,

I am out on the big pond tonight and everything is going great with the motor, no alarms, no limping, catching fish, etc...Then about 3 hours into the trip I turn the key and a quick fire, then nothing, turn the key again, nothing!!!???? A mild panic sets in, but then I take stock to narrow things down when I bring the boat in AGAIN!!! Depth finder on, aerator on auto for 2 hours, numerous runs up to start a drift, lights on cause of the rain, all of which I have done before...I fire it again and it fires, reluctantly, but starts. We make another drift , with the motor on and then head in. We get in fine, while I am waiting for my buddy to back up the van, I start checking stuff out...when i use the tilt and trim, all the lights dim, I let it run for a couple minutes, run the trim and it is fine for about 30 seconds and then starts to die, the trim that is, not the motor. Now what could it be? The battery is about a year old, got it from the dealer last spring. COuld it be the alternator, do boats have an alternator?

Any thoughts would be great.

Thanks,

BHS

I don't think you need to worry about the lights dimming. That's pretty normal. Just like starting a car with the lights on - they dim when you turn it over. Yes, boats have alternators but I don't think they recharge as well a car. My starting battery was looking pretty weak the other night too. Do you have battery guages? If it is starting hard it could be a good indication that the battery is low. I'd charge it over night and mess with it again. Don't think I'm even close to being an expert - I'm not! I just know it's nice to hear ideas. I think power trim takes quite a bit of juice. I can notice a definite difference on start up with freshly charged batteries. If you're running the trim up and down for 30 seconds on a low battery my guess is your draining it pretty good. I'm interested to see if I'm all wet on my ideas. Could be...
