90 malibu skier, runs great then wont start
My 1990 Malibu skier,mercruiser 5.7 starts great at first ,then runs fine,when i shut it down,it have problems restarting,i gave it a tune up with new points,etc...
dont know where to look next ...
i read some forums that said sparkplug wires can do this,and maybe a carb problem
and suggestions would be appreciated
thank u

by the way the boat runs great ,its just a starting issue after i drive it for a while

Ive been dealing with the same problem on my 86 supra. I went thru the alternator, starter, coil, battery. Now I am doing plugs, wires, cap, rotor, battery cables. Ill let you know what I find. My main issue is running for a while then whe I stop and kill the motor then go to restart it acts as if the battery is dead, then it fires right up.

I had the HEI module go out on a Camaro I had that caused this syptom. The coil and anything with a circuit board (which is probably nothing on boats of this vintage) are suspect for problems after warmup. Fresh spark plug wires are always good. Check the battery cable, too.

I had the same issue on my 98 Mobius. Had the carb rebuilt and solved the issue as far as I know.
