I have a 87 Sea Ray Seville CC with the Merc 4cyl. (165), i have already done all the upgrades to coolant problem, Alternator conversion, speedi sleeve the end of cam shaft. The problem is the shifting cable sticks and i want to replace that cable, and also i have a coolant leak because my bilge gets anti-freeze in it, and i believe it is coming from the coolant reservoir gaskets underneath (part that sits on top of the exhaust manifolds that has the radiator cap). Where do i order this gasket and cable from so i know that i am getting the correct and best style?
