    Starter will not shut off 1989 88SPL

    I have a 1989, Evinrude 88 SPL, which runs great. Yesterday I started the boat to put it back on the trailer. Once on the trailer, I shut the motor off and could hear something running on the motor. I figured it was the starter. I tried working the key a couple of times but it would not stop so...

    Am I too concerned about compression numbers?

    Did I give this 1989 140 Looper a fair Evaluation?

    I recently went and looked at a Ski boat which was powered by a 1989 Johnson 140hp looper. I was actually only interested in the boat for the motor. If, I had bought the boat, I had a guy I was going to give the boat and trailer too, after I pulled the motor. I found the boat had a bad floor...

    Switching from Alu prop to SST

    Is it the standard rule of thumb to go down two pitch sizes when changing from Aluminum to a SST prop.

    LU swap 1987 70hp to a 1991 70hp

    Well now that I bough it, let me ask. Can I use a LU from a 1987 70hp Johnson on a 1991 70hp Johnson? Price was to good to let go so I bought it before checking. Nothing wrong with the LU on my 1991, just picked this up as a spare. Thanks

    What caused this??? Can U Guess???

    Okay guys, I?m running a 1991 70 hp, on a aluminum bass boat. It?s new to me. I?ve had it out three times and each time it ran different. I found the answer here on Iboats. Poor idle , poor WOT would surge and miss, plugs kept fouling, and the last time out (after tearing apart carbs and fuel...
