    Hello. I’ve been working on a 1968 200. It’s finally nice enough to get outside and put some muffs on it. I’ve attached a picture, and within the red circle, I’m getting some oily bubbles. I’m also seeing oil coming from the holes right above the prop. Does this sound like I need to replace...

    Throttle shaft

    Hello. I have a 68 200 (20hp). It’s dripping some gas from the throttle shaft. I took apart the carb. There’s no o-ring or anything to prevent fuel from leaking down the shaft, and there’s a bit of play in the shaft. How can I prevent fuel from leaking down there? Also, I have this set to...

    Hello. I’m looking to rebuild the fuel pump In this 1968 merc 200. Every kit I look to buy has multiple diaphragms, but the fuel pump only had one diaphragm when I took it apart. Does the fuel pump need just the one diaphragm? And what is a good resource for buying the correct fuel pump kit?

    9.9 throttle sticky

    I have an 83 Johnson 9.9. The throttle is really stiff so that the gears/teeth want to slip. I took off the flywheel and magneto to clean the surfaces that rotate. It seems like there might be too much friction between the black, plastic throttle control cam and the roller cam follower, but...
