"I have a 1995 Hydrodyne grand
"I have a 1995 Hydrodyne grand sport inboard with a Pro Boss GT-40 EFI,PCM 5.8. HO Multiport EFI
it runs great, accept if I run it then stop for around an hour and don't open the motor cover. it won't start.(just cranks)When this happens I have spark. If I open the motor cover and wait a half hour or so it starts right up. it’s kind of like a vapor lock. I’ve seen on line other people with the same motor in different brands of boats with the same problems with no answers.
I think this was the first year for the multiport. somebody must have the answers?
