    Mercury Demand, Demand Linear, Demand Guardian

    Don't know if DL was at 95% because I forgot to show the Admiral for to scan the Techmate to see it. Don't see a difference just something to note for next time out. In most cases if I leave it on auto and get above 4500 RPM the boat starts to porpoise, so I take over. This time it didn't going...

    After dropping exhaust manifold to replace starter, I forgot to turn the raw water valve back on!

    VP 5.0GXi-B issue - low RPM/problem with a plane

    Welcome Tell us more about the engine swap? Was the Gxi a new crate motor (as complete drop in with new ECM) or one out of another boat? 12 to 12.5 bar (174 to 181 psi) is way to high for that motor. Either the gauge is bad or there is liquid in the cylinders. The one cylinder at 10.5 bar...

    exhaust bellow off again

    The exhaust bellow should play no effect on how the boat runs. Check inside the exhaust tube coming from the motor to see if something is clogging the exhaust

    Seeking advice regarding Volvo Penta 5.7GXi-HF fuel pump whine

    No need to bleed to see pressure above 10 psi, the HP pump will push above 60 psi. There are 2 things that control pressure, the pump and the regulator.
