[jkania]

hi i am new to iboats and see alot of useful info from alot of people so hopefully some one can help me i have a 1988 force 85hp it starts and runs good but when i put in water and drive 30 min and shut it off it will start right up but if i sit and fish for a couple of hours it wont start the primer is tight it cranks just fine but seems to have no spark on any cyl. i have had replaced starter,1 cdi,igntion sw.,spark plugs twice,coils, but all were used parts except ignition sw., all were replaced when i got the motor and the motor ran fine until recently any info is greatly appreciated. and if it sits over night it will fire right up again and start all over.

Next time it happens pull the fuel line off the engine, spin it over enough to pump all of the fuel and/or water out of the cylinders and carbs, hook up the fuel line again, prime it and see if it will start.

Could be numerous things.

Also pull the plugs next time and see if they have water on them or if they are wet when it will not start.

Get some in-line spark testers.The kind you can leave in while you run.
Then go for a ride.See if it sparks!!
No spark start with testing the stator. J.
