Hello new to the boating world love the info everyone has. I have a 1960 gale 25 hp 22de17b. I need to seal the lower unit seems to be leaking and seems to be slipping I need the part number for the seal kit, water pump, carb kit is there a kit with out the cork float and has the plastic one. The water in my barrel smells like gas but thats normal from what I'm reading but water is black. If oil is getting out water getting in.
