Hello, I recenty purchased a boat from my uncle and it's got a 75 horse chrysler on it. I know its the pre-1975 model because it doesnt have a mag. ignition.
Anyway the problem is that to start off it is hard starting, but with a shot of ether it fires right off. Once running, it idles rough. I have had it out a couple times and it when at wide open throttle it never really seems to have the power it should. When i go out on the water, it progressively starts running worse and worse until it will hardly hold 2000 rpm and if i shut it down it won't start again until it sits for a few hours. I have scratched out most the simple fixes such as the gas tank vent cap and improper fuel mixture. I have searched the forums and can't seem to find any answers. Your help would be greatly appreciated! Thank you.
