Hi, Whaler Fans:

We're new to the club having just purchased a beautiful 1983 15' Sport with "rare" center console (thanks, Mike!) One problem, I think having to do with boat not being used much in last year, is engine bogs down on occasion when accelerating to anything over no wake speed. Seems to clear up if I pump the heck out of the gas bulb primer. Another internet forum suggested cleaning carbs to rid of old gas residue, but I'm suspicious of a fuel pump problem. Anyone had similar experience?


BTW With minimal gear I got 35mph w/13x19 prop in still water! Love this boat!

This could be a couple of things:

--bad check valve in the primer bulb
--bad fuel pump in the engine; often they are just a "diaphram style" pump and can be serviced easily
--air leak in older fuel hoses
--clogged engine filter

In general, check the fuel system to be sure it is getting good flow to the engine. The primer bulb should hold its prime for quite a while.

Thanks! I got a new tank and hose, so I'm reasonably certain *1* it's in the engine. I will check into the fuel pump if the problem continues.

*1* Suspiciously, the "new" tank and hose did not prime easily, but I did get it working after some time (this on a remote island where the other tank was down to a half gallon of gas...whoops!) But the problem was happening with the older tank too...

I've solved the problem. In keeping with the discussions, it's FUEL. Turns out the brass connection on tank-to-Johnson fitting was not adequately sealed with teflon tape, so that the fuel line was losing its prime. After extended trolling/low RMP work, an air lock would develop and starve the engine.

Hope this helps anyone experiencing similar problems, especially those new to on-deck fuel tanks.
