    1977 Johnson head gasket

    I picked up this motor and was told it had problems running. First checked compression and was 90 and 92. Figure it should run with that and checked spark with tester and that would make the jump so all good so far. I put it in my water barrel and got it started and was pumping good but had to...

    9.9 Johnson prop question

    I picked up a 1980 9.9 Johnson and it came with 2 props. It had a 9 1/4 x 10 installed and the guy gave me a 9 1/4 x 8 with it. The 8 is like new but I see on this site that it says for sailboat use. What does that mean? Will it cause the motor to over rev or what would be the problems with...

    1958 Evinrude 18hp lower unit

    I picked up a resealed lower unit for a 1958 18hp Evinrude to replace the one I have. Mine has the short shaft and this one is a longshaft. I really dont want to take it apart if if I dont have to. I have no use for the longer shift arm so I was thinking I could just cut 5 inches off that one...

    9.9 Driveshaft groove

    I picked up a short driveshaft and shifter for my 9.9 Johnson longshaft off ebay to convert it to a shortshaft. It has a pretty good groove where the waterpump seal rides.

    Can anyone tell me the difference between the 1978 and 1987 Johnson 15 hp driveshafts? I see the part numbers are different. Is it only the lack of the o-ring groove on the 87?
