I have baught an 89 Bayliner Capri w/ a 2.3 L 4 Cylender. It will idle fine but at higher rpm's the motor misses or just has no horsepower to push the boat. I first thaught it was carburator problems or fuel pump probs but have changed both of these and it still does it. The motor has an electronic ignitionn in it, not the original points distributer. when u are running in the water, at full throttle , it will run fairly good for about 100 feet then slowly draw down to almnost nothing. Like it is running out of gas. Any suggestions would be appriciated. Thanks, Corey

corey,<br /><br />was there gas in the tank when you bought the boat, it so how long had it been in there. I recently bought a boat that did the same thing, once i ran most of the old gas out and refilled the problem seemed to get better. <br />Also, have you checked the fuel filter, my 4.3 merc. it needed to be cleaned badly.

Hello,<br /> There was little gas at all in the boat when I got it and I recently took it out this weekend to be exact. We filled it with gas and yes I have changed both the water/fuel filter and the filter on the carb. I think it may be the ignition myself. I have the old point dist. I think ill try it out and see what it does. Thanks

Sounds like a Fuel Issue......<br />There's More to the Fuel System, than the filters....

You may have been on to it with your first post about running out of gas, a bad float can cause this, lots of gas at idle but not enough when you increase the RPM's or even possibly a plugged vent line on the gas tank itself creating a vacumn in the tank (quickly check this by undoing the gas cap)

OK,<br /> I was in the yard playing with it and when I press the gas full throttle, it bogs down like it is running out of gas. But when I choke it a lil bit it will rev on up like it is supposed to. There is still a slight missing at higher RPM though. Thanks for all the help again. Corey
