    Sears Gamefisher 7.5hp - Weak Spark, Marginal Compression

    Seems I may have gotten too big for my britches. I am working on a Sears Gamefisher 7.5hp and I cannot even get a bark out of it. I worked a deal with a new acquaintance to get some sailing lessons. His kicker engine is a Sears Gamefisher 7.5hp, but he said it had not been used for 5 years. (He...

    How long for a muriatic acid bath?

    I'm removing a powerhead on a 1984 OMC 1.6L Sea Drive that was used in saltwater. I have the factory manual and have followed the removal steps scrupulously. I got all the bolts out and I've gotten the front part of the powerhead loose from the exhaust housing, but the two rear bolts that go...

    Thought I'd pull a powerhead today...

    Thought wrong. The engine is a 1984 Seadrive that was used in saltwater. A lot. I have the factory manual and went through each step. Lots of heating and tapping ensued. Except for wringing off the head of one of the long bolts that goes through the exhaust housing into the powerhead...

    Plywood transom exposed to moisture

    I have a 1984 Wellcraft Sportsman. There is a void area between the bottom of the hull and the bottom of the plywood core of the transom. This void area is glassed in, but a hole was cut through the fiberglass layer to allow water to drain from the boat. This hole allows water in the bilge to...

    Plastic Brake Lines - Whaddaya think about 'em?

    I'm upgrading my boat trailer for saltwater use and would like to upgrade the zinc plated steel brake lines to something more corrosion resistant. I've heard about plastic brake lines, which would be advantageous for my particular set-up because of their greater flexibility. Has anyone had any...
