I recently blew my exhaust boot on my 1988 85 hp force engine and looking for a new one. It has three ribs or humps in it and has a plastic plug toward the cowling and is inside the nozzle and spring running thru it. I have tryed everywhere without a hit. I took a piece of radiator hose and cut it off and made it work with epoxy but think it still leaks a little. If you got one give me a hollar on yahoo messenger cdn3700 or msn messenger cdn37001 or email me at cdn3700@yhaoo.com. thanks and god bless all charles
