" My 1983 40 Mariner has a rou
" My 1983 40 Mariner has a rough idle. It starts fine, runs good at fast idle and top speed. But at idle it appears to be starving for gas. Took it to a shop-- the guy replaced the fuel pump. Still a rough idle. He said its probably has low crank case preassure. Needs to have a seal replaced-- which would entail a rebuild- or a low preassure fuel pump can be added to prime the motor. I'm not sure what to do-- are there tests that can be performed for the crankase preassure? I had the engine checked before I bought and it has good compression 130 in each cylinder. Any ideas would be appreciated. Thanks Rick "
