Hey guys,
I've bought a boat with no comp on one of the cylinders on a 50hp Mercury blue stripe.
I'm wanting to know if this is something i can bite off ymself with help from the manual. I've rebuilt car motors before, and i've built myself a couple race cars (crashed first one )
Im quite technically minded, and have a good understanding, but know that being a 2 stroke, being carbie, its going to be quite different, albiet, alot more simplified, though very different.
I'm assuming that compression drop on the cylinder is likely to be a dead head gasket, and not likely a warped/cracked head (assuming again, that these motors have the same basic design as a car). Is it just a matter of opening the head, having it decked, and replacing the gasket? Obviously, if its more, than the crank comes out for a balance, the rods get inspected for fracturs, and the pistons get a clean/replace with new rings?
Or being an older motor, on a later hull (1988 4.7m Caribbean), should it be time to start looking for a newer motor?
Cheers,
jase
