    Her name is SNAFU! Because we have all been there... It's always something! This is not a derogatory name, think of it as an acceptance of the inevitable. Think endearing. Brought my friends from K.B.O out to enjoy some of the awesome Lake Trout fishery that Lake Ontario has to offer. They...

    1983 Johnson 70hp - Do I need to re-set the timing?

    Hello, I am in the process of waiting on a new timer base for my motor. I pulled the flywheel and everything looks good under there - top main seal is in good condition, etc. When I put the new timer base on, do I need to find some place with a test wheel and o/b tank to check the timing on...

    Advanced paint questions - Mixing...

    Johnson/Evinrude TnT - Prestolite vs. Showa Question

    I am rebuilding the Tilt and Trim for an '83 70hp Johnson in order to put onto my motor. It is my understanding that these TnT units fit most model years from the late 70's to early 90's. In order to purchase the correct seal kits, I need to specify if the tilt cylinder is Showa or Prestolite...

    1984 Johnson 70hp intermittent ignition issue

    The motor has a problem with intermittent loss of spark. This only happens when trying to start the motor, when it is warm it runs like a top. Based on advice from my local outboard repair guru, he says that my issue is probably the timer base. How would one test a timer base on an '84...

    Eliminating "below the water line" thru-hull fittings

    I am in the process of trying to make a decision on what to do with two holes at the bottom of the stern of my tin boat. Previously there was a livewell aerator pump and presumably what was used as a drain. These functions are no longer needed, and I don't like having two extra holes below the...

    Aluminum Closed end rivets for aluminum hull repair

    Based on what I have been able to find for rivets, all of them that are larger than 3/16 have steel mandrels. Will these work for a hull repair being that the mandrel breaks off inside the rivet, and will rust? What do people typically use? Where is the best place to buy? Thanks!
