Motor dies during warm weather

I have a '96 150 HP Fast Strike that dies during acceleration (starved for gas) once outside temps go above 75. It's been to several shops and I still have the same problem. If you reach back and pump the bulb the engine will run fine. All kinds of things have been tried. I'm at the point where I'm thinking about installing an electric fuel pump to keep the line pressurized. Anyone else out there heard of this problem? I know one other guy that had the same problem and he just got rid of his boat.

It is starving for fuel. You are getting air in the fuel lines,leaking at the primer cap, or all the black gaskets are falling apart or swelling from the ethanol. The fuel pumps also do not react well with ethanol. 10% is the max, Pasadena,Houston and our surrounding areas are seeing well above that in some cases. (More than you want to know). We are having to change out and rebuild complete fuel systems in this area. It can get into the $1000.00 range pretty quick. You will need to check all the interior surfaces of the fuel lines also, they peel off like sunburnt skin! I would try to prime the bulb as you accelerate, this will tell you if it really is a fuel supply issue.

I think I'd trade being able to walk on the lake (ice) for having fuel problems and 75 degree weather.

Good luck with your fuel problems, just couldn't let the 75 degree thing pass...

COME ON SPRING !!!!!!

I forgot to mention that I moved here to Pasadena last summer (got married again) from the Panhandle area (Pampa). And this problem has been going on for about 3 or 4 years now.

Also, I usually am able to get to the primer bulb before the engine dies - you can hear the engine pick up a little bit and the bulb gets tight again. After the grab and prime deal it's back off to the races again. Aside from the pain in the rear priming problem, I know that this sequence can't be good for the engine and I'm afraid it could affect longevity of the engine.

All the fuel lines and water sep filter have been checked and/or repaired. The manual choke cap & lever have been replaced. And all of the under-cover lines & fittings have been checked. I still think it's some kind of vapor lock situation, but I can't get anyone to agree to the idea. BTW I have only run the Premium grade fuels in this engine from day one

If you're located here in Houston, (rudetech1) gimme and email - I'd love to talk to you! (gwc43@comcast.net)

P.S. I have had the VRO replaced on this engine.
