I've got a '03 150HPDI that is warrantied through 2010 (Yamaha's YES warranty). Upon take-off, the motor hesitates a few times almost as if it's being choked off or is not getting fuel to the motor, but will get going and run fine once I give it enough throttle and get planed out.

I've tried different fuel types and always use the Yamaha oil. I'm not sure if it's a problem with the spark plugs, fuel pump, fuel filter or what. But I wonder if I take it in to be checked out and worked on, if work of this type is typically covered under warranty? I've not had to take the motor in for work before, and am hoping to find out before hand if I would get a bill for this type of work or if warranty will cover it.

Anyone have an idea if this would be covered under the warranty?

Thanks!

The spark plugs and the fuel filler will not be covered. The fuel pump would be I think.

DB,
I suspect that you have some issues with fuel sludging in the fuel injection system. It is possible that you have some injector issues as well.

It is a toss up as to whether it will be covered under warrenty or not.

Take it in and get it fixed, whether it is covered under warrenty or not. The only thing that is going to happen to your motor is that the problem is going to get worse.

You might think about getting a 10 micron fuel separator installed on your boat if you don't already have on in place. With todays gas, lots of fellows are adding the separator to keep fuel issues from getting to your motor and causing motor issues. Better to trap the fuel issues in the fuel separator which may be easily changed, than plugging up injectors etc. and having to pay a repair bill.

Take care

p.s.
I assume that you keep fuel stabilizer, sea foam, or equivalent in your fuel at all times? If not; I suspect that that could be making your problem worse.

You have never had it in?


It's an '03... ...:)
I'd say it's time to take it in just on general principals...isn't it?

Thanks REW, that's great information! I'll definitely have to bring it in and will also talk to the dealer about what you had mentioned. Hopefully whatever the case is it'll be covered under warranty and I can save a few bucks.

T-mac...I myself have owned the boat for almost 2 years now, but haven't had a problem with the motor up until now. I just haven't had to bring it in for repair work. Winterizing, yes. Repairs, no....not until now.

Ahhh, now I see.

Yeah, that's my bad. I should have mentioned that I bought it used from a private seller. The guy I bought it from was pretty meticulous as well to my knowlege. I just need to get it in and have it taken care of. Hopefully it'll cost little or nothing.
