My logs are leaking internally. My oil looks like chocolate milk. I suspected they would leak when I put them back on after finishing my transom and they did. I only ran it for a minute or so on the muffs. Anyways I was thinking of buying everything from this guy on ebay. Here are the parts I am thinking of buying. http://www.ebay.com/itm/MERCRUISER-HI-PERFORMANCE-EXHAUST-MANIFOLDS-1982-OLDER-/310232982795?pt=Boat_Parts_Accessories_Gear&hash=item483b53a50b and http://www.ebay.com/itm/ALUMINUM-BRACKET-SB-CHEVY-SWP-ALTERNATOR-POWER-STEERING-/310157701421?pt=Motors_Car_Truck_Parts_Accessories&hash=item4836d6f12d and http://www.ebay.com/itm/V8-THERMOST...at_Parts_Accessories_Gear&hash=item48465de4cb . What do you guys think of all these parts? I dont know how I feel about stainless gaskets. Will they make a good seal? I figure the whole conversion will cost me $950. Logs would be $750 so I think its a worthwhile upgrade but would like some input before I buy.
