    Volvo 3.0L engine Block

    Ok that being the case I wouldn't weld it but have seen some folks grind it clean and use JB weld on it. This will only work if the water doesn't get into the oil. It can take a couple uses/hot & cold cycles for the crack start pushing water into the oil. When my neighbor was too lazy to drain...

    Volvo 3.0L engine Block

    By short shaft do you mean short block ? Short and long block are used the describe the engine block with rotating assembly without cylinder head (short block) or with cylinder head (long block). I assume by cracked lower unit you mean engine block vs lower unit aka outdrive? Volvo and...

    Trust the dealer?

    Agree with the others I think 20 would be a little low. What's the max hp rating of the boat? I'd think you want to be close to the max rating.

    Truck cam with captain's choice?

    The truck cam and stock marine cam are usually interchangeable, unless someone swapped the truck cam out during its life. Captains choice uses the same wet exhaust as stock just diverts it between the elbows and the transom housing wye pipe, so in terms of reversion potential it would be the...

    Ford 302...21 foot fiberglass with cuddy

    as stated a 15, but that is so low in pitch and you would barely be getting into proper rpm it makes me think there may be others issues as well.. . Like wrong drive ratio. i would also take the other steps to ensure your tach is accurate and engine is in good tune, unless you already have

    Ford 302...21 foot fiberglass with cuddy

    as bondo said between the drive ratio and the prop you should be able to get it to a much higher rpm. If you dropped to a 15 youd likely see 4300 rpm or so. since this is newly assembled id verify your tach vs a shop tach, make sure you are getting full ignition advance, and read the plugs to...

    Mercruiser 3.0 = Chevy 181 CID = Small Block Chevy Valve Train? 1:65 Rockers?

    Merc 140 fuel pump install, no ros?

    Would appear if you look at parts diagram 1A, 1B,1C that the vent was put on after your serial started at 044xx and up. https://www.marineengine.com/parts/mercruiser-sterndrive-parts/140-gm-181-il4-19721978/3332138-thru-5157668/fuel-pump-fuel-filter-and-carburetor looking at the serials if you...

    Newer Mercruiser Cooling System Questions . . .

    That would be my take as well. When you look at the modern V engines (bot these merc and automotive) none have an intake water crossover like back in the day. Yes 10 lbs of stuf in a 5 lb box...

    Newer Mercruiser Cooling System Questions . . .

    What this looks to be is a bigger version of the thermostat housing that would be on top of the intake on an older chevy based V engine. I suspect there is no water crossover in your intake. This collects hot coolant out of both banks of heads and from exhaust manifolds. Thermostat is in top...
