Force 125 Starving.

[Steel Reserve 211]

First of all, thnaks to all of you who have helped me over the last year to feel confident about boating. <br />Here's my question: I can cruise my boat at about 20 mph all day long. I can even go above 30 mph, but if I stay above 30 for more than five or ten minutes, it really wants to die. I can feel it starving and surging. So I take it down to Iidle, and it still sounds like it's starving, so I finnesse the throttle to give it more gas and keep it from dying. After about five minutes, I can get going again, and cruise on home, frustrated. Simultaneous to the "starving", the fuel guage is erratic. So I know it's an electrical problem. How do I find the problem?<br /><br />Thanks.

Re: Force 125 Starving.

I'm thinking it is not electrical in nature. If it was, it would be accompanied by an ignition miss that wouldn't go away.<br /><br />Fuel gauge should be able to draw plenty of power from the battery to operate normally.<br /><br />My guess is fuel starvation, caused by a weak old fuel pump diaphram. It simply isn't keeping up with the fuel demand.<br /><br />Or the needle valve on the carb is partially clogged, not allowing the fuel to flow fast enough.<br /><br />I would change out the diaphram and gaskets on the fuel pump. It probably need sto be done anyway.
