Hi all,
Been surfing the site and getting great info. Now I have a couple questions. took our 1984 Contessa 2850 with Volvo Penta 4.3 for a spin on our madden voyage. She ran for a couple hours about , just looking at the scenery on shore. Got to the end of the lake spun around to head back to the dock and opened her up to 17/18 mph for about 20 min then hear change in tone from the rear, out the back. Smoke started filling the cabin & coming out the throttle controls. After checking the wiring, which the smell was like rubber or electrical wiring all was fine under the dash. Looked in the engine compartment to find 1 of the exhaust boots had nice size hole melted in it. We duct taped it up and putted back to the dock. Did want to strain the tape.The next day I started to remove & replace the boot & its rock solid & the other one has a small hole in it to. Is it best to pull exhaust manifold, because it don't seem I could get them off with out cutting them up or put them back on with that small a gap. Is it possible they just broke down from age? I also noticed some water below water pump. Maybe 1in or so.The guy we got it from replaced the raw pump impeller but not the circulation pump. What's best way to test the pump? I've been told I can get a heavy duty Chevy water pump to replace it, is this a good idea?
Thanks,
Dale
