    Dual outboard controls and counter rotation for vintage omc motors

    Hello, I have been considering a project for a while now and it is time for me to ask for some input. As always, I like to start with an ideal and then settle for less when it turns out to be impractical. I want to run twin 30hp or 35hp vintage OMC motors (56-59) on a larger aluminum hull...

    Hello, i am getting ready to reseal a lower unit on a 1957 evinrude 35hp. there is scoring on the shaft below the impeller where it sits in the seal/bearing.

    Hello, I have one that has me stumped 1962 Evinrude fastwin 18 Only runs at 1/2 choke and dies if I try to idle down below "start". Smokes much more than my other motors. Compression is OK, 110/118 Spark is good. My tester is "missing" right now but I got both to jump 3/8" on a test lead...

    1979 Mercury 7.5 powerhead compatibility

    Hello, My friend asked me to take a look at his 1979 mercury 7.5HP electric start motor. It didnt turn over this spring. I opened a few things up and it is pretty corroded in there. Probably not worth trying to save. What information do I need to identify potential candidates for replacement...

    1956 Evinrude color match, approximate

    Hello, One of the "parts" motors that I picked up to put my 1957 evinrude lark back in the water was another 57 lark, complete enough to not take parts from but instead also fix. The real issue with it is the color. Someone took the time to take it all apart and paint it bright metal flake pink...

    New prop concerns. Balance, blade shape.

    Hello, I recently purchased a new propeller for my 1956 evinrude 15. I decided I wanted a spare anyway while I sort out having the old prop re-hubbed. The old prop is the (original?) weedless 3 blade with the long swept back blades. It is stamped 9x11 on the root of one of the blades. I ordered...

    1957 evinrude lark seized, damp crank case.

    Hello, I picked up a 1957 Evinrude lark (35HP) last month. It has spent the better part of 40 years in a dirt floor basement, without plugs... As you might expect, it is stuck solid. As soon as I got it I pulled the exhaust side covers off and sprayed the cylinders and crank case liberally with...

    What's it? 1957 Evinrude lark, tow eye?

    I recently picked up a 1957 Evinrude lark. Its complete but rough. It has a feature that I cannot identify. On the leg, just above the lower pivot point, is a 2 piece, clamped on eye. Clearly made for an OMC leg. It is stamped 55. What is this? My first thought was some sort of motor support...

    seeking Hub replacement service for 50s pin drive props

    Hello, Forgive me if this is not quite the correct category, but as it is specific to props I thought this was the best fit. I am looking for some shop suggestions for rehubbing service on several pin drive OMC props from the 50s and 60s. I am located in Vermont so the closer the better, but as...

    1956 Johnson 30HP prop nut confusion

    Hi all, I have a bit of a conundrum. I am ready to do a water test on my 1956 Johnson 30HP and have discovered that the prop nut that I ordered (and the alternate one listed in my parts manual) are both threaded nuts. The propeller shaft on my motor is not. I thought nothing of it until I went...

    Tachometer and/or Generator for 1956 Johnson 30HP

    Hi All, I have been searching but have either used the wrong terms or looked in the wrong places. I am looking for 2 things. The first is a tachometer that is compatible with the original (stock) 1956 Johnson/Evinrude outboards. I know about tinytach but I am putting a dash together for a...

    14' Duratech, Beyond saving?

    Hello everyone. I have a 14' duratech that has been, to say the least, neglected. At some point in its life it was run onto a submerged obstacle. There is a crease in the hull near the keel that starts at the bow and continues back. About 6' from the transom it changes into a rip and runs...

    50's Duratech Sealine?

    Hello, New to the forums, first time writer. I just pulled this Duratech Sealine[?] out from behind my fathers barn where it has been for the last 30ish years. I had hoped to make a quick repair of it and to put it to use. I still think that I can do the repairs but when I discovered that these...
