    3 Blade to 4 Blade?

    So I'm having a heck of a time with getting a decent holeshoot and up on plane. If I have more than two people in the boat I have to move one to the front to get it going. If I am trying to pull a skier it drags them for a bit before they can pop up. Once we get going we are fine. I currently...

    We bought a boat recently. Ran great at the test run with the previous owner. Get it out Saturday runs great.

    Stumped! Need Advice. '75 Mercury 650 3 Cyl

    Here are the symptoms. Having a hard time timing the motor. It doesn't want to keep the timing it seems, it also seems like it is missing when idling. When it idles it surges. IF I can get the RPMs under 1000, it feels like it has a miss but often it will rise the RPMs on its own. Sometimes the...

    New Poppet Valve, T-stat, Impeller = no water out tell tale? Merc. 65hp 3 cyl 650

    So, perhaps I am just paranoid. I have rebuilt my motor. Stripped down to the crank to replace two broken reeds. New seals on the block all the way around. The poppet valve was shot, the thermostat could open by hand. I replaced both. I also dropped the lower unit and put new seals and...

    1975 650 3 Cyl Thunderbolt Rough

    All- I purchased the boat with the motor, it wasn't running, but I got it for a decent price. Anyway, I fixed some "broken" parts on it and started her up. She sputtered. I took her down to the block, removed the distributor, starter, and disassembled the carbs. Found that the piece that...

    1963 Johnson 35hp

    So I get a text from a friend who just bought a boat. We did all the initial testing and everything, motor works great, however is wife said that it has dripped oil on the garage floor. In my experience 2-stroke motors will "leak" a little after being ran in the water. However, I am curious...

    '75 Mercury 650 Cyl Thunderbolt Motor

    Got a boat from a guy today, he said he was monkeyin' with it and broke some piece of plastic off the throttle actuator. Said the park was either .75 cents or 15 bucks. But I cannot for the life of me find where this part would have even been on the motor. Any ideas what this guy is talking...

    proud new to me 1962 Starcraft Run-about owner

    Re: proud new to me 1962 Starcraft Run-about owner Here's my first attempt at a layout. I don't have absolute dimensions on the boat or the trolling motor, but I did look up some dims on the hull and used those are a base line.

    proud new to me 1962 Starcraft Run-about owner

    I sold my old boat a few years ago and regretted the decision. So a friend of mine decided she wanted to sell her Starcraft boat with a 28HP Johnson Super Seahorse. I think this is a Jet or a Jetstar. Not sure the difference. I tell ya what though this boat has a lot of potential and is...
