    Seafoam for an I/O

    I happened to notice Seafoam in the local auto parts store. I have heard many folks swear by it use to decarbonize outboard engines. Will it provide any benefit to my Mercuriser 4.3LX motor? I have a lot of time on it, but it runs well and has good power.

    Is there a good Bow-lifting Prop?

    I looking for the subject for my 1977 inline 150HP Merc. My boat runs fairly flat at high speed with a standard Merc 3 blade prop(12-3/4 X 19-21 pitch), and I think more bowlift would allow higher top speed. However, I need good holeshot, for water skiing. Is there a prop that had both good...

    As close as you can come to sinking!

    Many years ago I was out in Raritan Bay NJ near the ammunition pier, in my 14' runabout. Now I know that it gets real rough there in the afternoon (4' waves), but at the time I was ignorant. We stopped to fish, and took several waves over the transom in rapid succession. Since we were about...

    Cooling Water circulation pattern on 1977 IL 6 150HP OB

    Can someone advise on the path of the cooling water after it leaves the watertube in the center of the exhaust extension? I will guess it cools the cylinders (number six first) as it travels up to the number one cylinder, then splits such that some water goes to the Cylinder head and some goes...

    Merc IL 6 left in saltwater, can it be flushed?

    I have a 1977 Merc 150HP OB. I leave the boat docked on the bay (saltwater) all summer. Is there a way to flush it after use with freshwater without trailering it?
