    MerCruiser 5.0 Carb Engine Compression Test, Two Piston came back with Zero

    if it was vented to atmostphere, it would have all evaporated by May in such a large tank Not sure you need to do anything with only one gallon of fuel in the tank.

    V-P 5.7 Gxi intake on 383 stroker?

    You have to throw the accessories , raw water pump, exhaust and coupler away as they are different than the VP stuff. The block is the same. Additionally the Mercruiser fueling is a bit lower than what VP does, so you're giving up some performance And they come with the block-busting single...

    V-P 5.7 Gxi intake on 383 stroker?

    the 8.1 big block put out about 60% more torque than the 5.7 at 2000 RPM. 440 ft lb for the stock 8.1 and about 275 for the 5.7. the 375sp is a fueling cut-off rating. same block with a minor change to fuel map will do 475. More if you want to play with injectors and other bits from Raylar...

    I believe the dry weight is 5833# for your boat. which means the wet weight is close to 7K. thats almost needing twins weight category. Not sure there is enough power in a small block for getting out of the hole quick enough to go skiing. with a change to the IPS drive, would make one heck...

    1981 Mercury 7.5 2 stroke

    you can get the manual from Mercury or find them on-line at sites like oldmercs or AOMCI for the 7.5/9.8. look at the 1980-1985 motors as they are all the same. the first thing you need to do is pull the leg, measure the vertical drive shaft diameter, then order a raw water pump kit. the...

    Trailer bleeding brakes. Part 2

    you should not need sealant. the three types of fittings in the brake system are the bleeder which is a tapered seat, and the inverted flare nuts or crush washers in the lines. none need sealant.

    Hole through transom

    no need for loctite or even rubber washers. a simple bolt thru the hole with some elastomeric marine sealant like boat caulk would suffice. if the hole is small enough, just the elastomeric sealant
