Hello Everyone,
Have a 26 ProLine with a T.B.I. volvo 5.7. That first started with a whine sound coming from the fuel cell that is located in the front of the engine. After checking fuel press. high side pump was bad.Replaced pump everything was good.Boat sits for about 6 months. About two weeks ago I was leaving the breakwall and powering up when the boat starts hesitating and starts dieing.Limp it back to the trailor and take it home.I was hearing a whine sound coming from the fuel cell I disconected the vaccum hose that comes from the pulse sensor to the fuel cell and noise went away.I have noticed that the psi on the pumps look ok at idle and below 2500 rpm. But once I put it in the water and get above 3000rpm the press. drops on the low and the engine starts to buck.I have replaced fuel filter/ checked tank for dirt,ok// checked my S.L.O.W. oil switch and thats ok. I have replaced the cap and rotor used a remote fuel tank.Before i spend the $700.00 dollers on the fuel cell I need to make sure that is the problem. I read that someone had an issue with the ign.coil. can this be it? under an extrem load that the coil can be causing a lack of power? At this point i would apreciate the help.
