    1975 Evinrude 25 problem - jumping out of gear and/or blown head gasket?

    I have been working on this new to me 1975 Evinrude 25 (25503B) recently. Compression numbers were 124 top/118 bottom and it fired right up once I got it home, so I decided it was worth a little work to get back on the water. Unfortunately when I finally took it out for a boat test, I was...

    16' tin and honda 9.9, need help getting in the ballpark

    I recently picked up a Duranautic 16' (open aluminum boat). Because of horsepower limits on a bunch of reservoirs here in NJ I am putting a Honda 9.9 I scored for $50 on it. I understand how to use prop calculators, but the problem is that the outboard I bought did not come with a prop to test...

    lift point for 1989 85hp?

    Picked up a new to me 1989 85hp Force today. It's heavy and I don't see a loop to hook my cherry picker (engine hoist) to get it off the truck and into the garage to be tuned up. I bought the Seloc manual for it, but it does not make any mention of how to lift it. My 1970 40 hp Johnson has a...

    1970 Johnson 40 hp Awakening

    Hey, I got this Johnson 40 hp motor this week. It's a 1970 Electrashift (Model 40ESL70A). It hasn't been run in about 5 years I am told, so now I am working through getting it back to life. To start, I was just doing an inspection prior to cleaning, and I came across my first question. On...

    Will 40 hp do it?

    Hey there. I'm new to powerboating and have been doing some research here on iboats to find out what it will take to get my vessel up on a plane. The boat is a Cobia Sunskiff 156 which I have not been able to find too much info about online. It's a 15' boat with a 6'10" beam and the hull...
