    Adding 2nd battery?

    Yes, but I wouldn't do it. Bats are heavy and the first Bat is screwed to the deck, screw the other one the same way, just don't use long screws. Remove on of the screws holding the first Bat and see how long they are and do the same

    Volvo penta 4.3 flooding

    Flooding is either the needle valve or float. Just like a full bucket of water, if ya open the valve and more water runs in the bucket, it will over flow. If valve shuts off then no overflow If you have a brass float and its leaking then fuel starts filling up the float and it will sink and...

    5.7 350 engine Mercrusier 2011 - RPM low issue under a load

    Still hard to tell, not enough info as yet We know compression is within spec and so is fuel pressure Assuming the motor use to run fine under load, correct? If it did what happened when it stopped running good? What do the plugs look like? Look at the distributor cap, they are known to give...

    High fuel pressure issue

    Probably but is most likely just be a bandaid fix for your issue and wasn't my point when discussing VL. I have a hard time getting that it won't stay at 30, and more so that few pounds more causes it to run worst. Currently wonder if the Reg is not the correct part number, and that...

    High fuel pressure issue

    Mostly talking about MPI, not so much with TBI Autos have flow thru ventilation and excess fuel is returned to tank Most marine (not all) there is not much ventilation when motor shuts off and the excess fuel returns to the canister fuel filter. So heat builds up, boils gas in fuel rails...

    Volvo penta 4.3 flooding

    Putting oil in gas will make it smoke some but unless there is a lot of oil it would still run I has to have something to do with the needle and seat. You said have tried twice, but its still the only thing that keeps fuel from over flowing. That is unless your pressure gauge is off and its...

    5.7 350 engine Mercrusier 2011 - RPM low issue under a load
