    1979 Johnson 150 Exhaust issue

    I have a 1979 Johnson 150 that I got running for the first time in 12 months. I did the proper starting methods when you have had a motor sitting for a long time. To my surprise it started right up and runs like a top. The only problem I am experiencing is a small poof of smoke randomly (once...

    What boat would you recommend?

    I have a budget of about 1500$. I bought a 1985 19' Ebbtide DynaTrak SS with a solid 1979 Johnson 150 on it but the boat was full blown rotted. Not a single spot of the boat was solid. I don't want to invest that much time to resto. that boat although I have bought the supplies. I figured it...

    70 HP mercury with brown discharge out prop

    Trying to figure out what gaskets to replace. The lower unit gear housing maintains a level of oil but the propeller slowly leaks out a light brown discharge which i am assuming is a mix of water and gear oil. What gaskets or O-rings or bushings separate the 2 and how easy are they to change.

    1990 70 HP Mercury will not idle

    The motor turns over and will idle for 5 mins and then stalls unless some throttle is applied.
