[QUOTE="lugoismad, post: 457812, member: 16518"] I bought a 1996 Pontoon with a 1996 Force 40hp engine. When I first took it out, it ran like crap. I took it home and took the carb off of it it cleaned it thoroughly and replaced the spark plugs. I also installed a tell-tale and put in a new water impeller. I took it out again. It ran much better. However, once it got hot, it started running crappy again. It wouldn't idle and even at full throttle was missing hard and only pushing the boat a few miles an hour. I verified the tell-tale was pushing out water and it wasn't super hot or anything. Just ordinary warm feeling, but not boiling. I've ordered a new coil pack set for it. From what I've read, thats the most likely cause. I've also bought a fuel pump rebuild kit, which from what I've read should help with it idling. I have a fishing trip coming up in 3 weeks and I either have to have the boat running or I have to pay $80 a day to rent a fishing boat, because I've already paid for the cabin and slip rental and its too close to get a refund. Is there anything else you would suggest I try? Thanks! [/QUOTE]
