    no. you need to replace the thru-hull fittings and not attempt to cap them. the fittings themselves are cracked and need replacing if you put a rubber drain plug in the cracked plastic, the plastic will fail and you will most likely sink the boat you need to replace them. Plastic fittings...

    470 4 barrel conversion, one cylinder missing

    the only difference is the manifold and carb. so yes, you can slap a 4 bbl on a 470 and get a 485. nothing special about a marine motor except the core plugs are brass or stainless, the head gasket has a stainless core and the cam has very little overlap due to the wet exhaust. if you want to...

    Can someone PLEASE tell me which bellows are which? taking on some water...
