Hi
I have a 1986 Vanguard boat with a 140r mercruiser engine (raw water cooled).
Problem: Boat runs fine while pulling tub for about two hours and then quits. If I let it sit over night it will work the next day as if nothing had happened.
Had the boat serviced last year by a marine tech and replaced the fuel pump and the ignition coil but it didn't solve the problem. Had gear oil changed and no water in it.
Tried new tank of gas and still have the same problem. Temp guage only goes up to half way line. Extremely frustrated.
