I just bought a pontoon boat with a 1971 Chrysler 70hp and right before we put it in the water I noticed that the fuel line squeeze bulb was cracked and leaked a little fuel on my hand. The boat ran pretty well for a couple hours with minor cutting out but we never opened it to WOT. When I took the wheel I opened it to WOT and it bogged down and didnt run well all the way back to the ramp. When I took it out of gear and it was not under load then it picked back up. My question is do any of think the cracked bulb in the fuel line had anything to do with it? Or just carbs.
