I just bought a boat that has a Volvo 7.4 Gi PWTR engine. It is running great, but the LP fuel pump starts whining after it has been idling about 3-5 minutes. It sounds like it is caveating, then it passes the air and a few seconds later the cycle starts over with a quiet whine that gets louder...
Lots of good recomendations on here so I though I would ask for one.
I have a 2008 Tahoe Q6 with a 220 HP 4.3 MPI Mercruiser Alpha One.
The boat is:
Length 20' 6''
Beam 96"
Weight w/ Engine (approx.) 2730 Lbs
Fuel Capacity 45 Gallons
Deadrise 20 degrees
Draft 24"
Deadrise 20 degrees...
