"Just purchased boat with 1987
"Just purchased boat with 1987 3.0 Mercrusier Alpha One. Boat was sitting for two years. I did a tune-up on it with tune up kit, new plugs, fuel filter; also replaced battery, changed oil and filter (oil had water in it).
Started OK and ran fine for 1 hour, then developed skipping after heating up. Tried the next day with same results.
I did not change plug wires, put they seem in pretty good shape. Do you think coil is the problem, or any other ideas? Thanks!!"
