    Replacement fuel cap

    Does anyone know where to get a replacement fuel cap for one of those discount store Attwood 6 gallon portable marine fuel tanks? I searched all over. All I can find is for Moeller. The vent cap broke off mine and gas squirts out in my boat from the sloshing around.

    Homemade plywood boats

I have a perfectly good 12' aluminum boat, a 14' fishing boat, and access to a larger boat that can go out on the lakes. But curiosity is getting the best of me and Im a thinking about building one of...

    Opinions and advice needed on my stringers

    This is a 14' fiberglass V hull fishing boat. I have a 7.5hp outboard on it. I believe it is a Sears model but its old, probably from the '50's. It was taking on a little water. Not a lot, but I could be out on the lake for 3-4 hours and there was maybe 2 inches accumulated back at the...

    Cant get a screw out

    Im trying to change the lower unit oil in my little 1979 Mercury 4.5HP. The vent screw is fairly small. Someone had painted the motor and now the vent screw is stuck in there fast, and I cant get it out. It's starting to strip and the screwdriver wont grab. I figured I better stop trying and...

    Emergency Starting if Rope Broken

    I have a 1979 4.5hp Mercury. I want to start it with the cowling off to see if my carb repair was successful and it wont leak gas. The pull starter is inside the cowling. The top of my flywheel is identical to the pic I attached. This would also come in handy if the rope broke out on the...

    Carb model?

    I have a 1979 Mercury 4.5hp outboard. I have verified the year by the serial number. I am looking for a carb kit. Here on iBoats they do not list my year. They list the 4.5's in 1980-1985. They list the 4hp 1 cylinder (which mine is a 1 cylinder) but none of them include the year 1979. Now...

    What are these parts?

    This is a Scott McCulloch, 1959, 40HP motor with electric start. I am not getting any spark, even after changing the plugs, condensers, and points. I am wondering if I dont have something shorted out. Just wondering what these parts are since they all seem to be electrical and possibly the...

    Weak Spark

    Scott McCulloch 1959 40HP model 336A. Had a mechanic look at it cause I had no spark. He cleaned and reset the points, said he was getting very weak spark probably not enough to run it. His opinion was either the coils or magnets in the flywheel were bad. The "big" coils are Wico X11352...

    Is my motor smoking too bad? (video link)

    This is a video I took of me starting and running my motor in a test tank. It is a 1983 Chrysler 7.5HP. Some questions: 1. Is it smoking too bad? I know all 2 cycles smoke but this seems excessive. I am using 50:1 in it, no stabilizer or anything else. 2. Do the RPM's sound OK when I...

    Spark Plug Wires

    Scott-McCulloch Outboard model 336A, 40HP year 1959 Can I splice the spark plug wires? It looks like the spark plug wires are permanently attached to the coils and I dont want to buy new coils. The wires are bad and arcing all over the place when I crank it over. I picked up some 7mm spark...

    Engine revving up SOLVED

    Got my Chrysler 7.5hp going. Only problem is it keeps revving up then slowing down, revving up and slowing down. Just like someone is twisting the throttle on a motorcycle up and down. I have always used the term "loping" but I searched for that here and found nothing. Other than that the...

    1983 7.5HP Recoil Starter

    This is a Chrysler 7.5 horsepower motor, 1983, model number 72H3F i picked up for $50. The manual recoil starter just spins around and around, the rope isnt on it anymore. Im guessing when the rope broke all hell broke loose with it and it unsprung itself and broke something. When Im playing...

    Throttle Cable Help

    I came across a 1959 40hp Scott-Atwater. The the throttle and shift levers were attached with cables but the levers seem all stripped out, and naturally I took it apart and it all fell apart (stripped out, pretty much junk). Im wondering if there are some generic throttle/shift levers a guy...
