Hey Guys,
I am still shaking down my new (for me) 86 Donzi . When I bought it the kid said he thought it needed new manifolds, because it was over heating. Well, I put the rubber hoses for the exhaust back together and ran the boat. it ran pretty good. no overheating. That turned out to be a faulty temp sender. so after about 10-15 times out on the lake, it quit on me yesterday and I was towed in. I fussed with it for a while and discovered the starboard side rear spark plug wire was off. I little bit excited about the possiblity of more power and speed, I checked the plug, hooked it up and the engine fired right up. It sounded better than ever. I took it for a ride, and boy what a difference. BUt, within 2 mins, I smelled burning rubber, and saw lots of smoke. I made it back to the dock, but the entire starboard side exhaust burnt itself to death. it blew holes in all three pieces. Is this a plugged riser, or manifold not getting the water to cool it? IF I need a replacment, are the Emi thunder, or stainless marine headers worth the $1000? Also, the s-pipe system form eddie marine is listed at $1200, that seems like alot for a couple pipes? how much are the custom systems? Anyway, any advise is appreciated,
James
