    1989 150xp Stalling At High RPM

    I have had this boat (Stratos) for a couple of years. About 6 month ago a cylinder blew out and I had the motor rebuild. Rebuild was okay but not sure it was the best job. Have compression and spark on all cylinders. Boat started struggling to plane out. It would plane if I took it slow...

    No Compression One Cylinder

    Just had a rebuild on my 1989 150xp. Thought it would run great, and did for a while. Just the other day it would not plane out at full throttle. Called mechanic and he suggested I replace the sparks. Did that but no change. Today I ran a compression test. 105, 100, 100, 92, 0, 100. Not...

    Lower Unit or Linkage Johnson 150xp

    I purchased my boat a few months ago. It is a older Stratos (1989 I think) and has a Johnson 150 xp. The boat runs really good, once you get it there. When I start the motor, and it takes a while for it to warm up, it goes into reverse smoothly but not true with forward. When I shift into...

    Solonoid Connect to Carbs?

    I need to know. How does the solonoid move the choke plates? I cannot see any connection between the two, that is a physical moving part. Have a 1980 70 hp Johnson with the solonoid with a red lever. Do I have a part missing?

    1980 70hp Johnson coil installation

    I have been having problems with what appears to be no fire on the number 3 cylinder (bottom one). The way I found it was by just pulling off the plug wires while it was running. Both of the others cause the motor to die but not with the number 3 removed. Then I checked for an ark and found...

    Bad Rectifier?

I then did something I know everyone in the forum seems to disaggree, but I went on and installed an ammeter in series on the positive side of the battery. The ammeter bottomed out to the negative at cranking and after starting...

    1980 70 hp Johnson problem at high rpm

    Just got an old boat into water. The motor is 70 hp and seems to start and run good, except at high rpm. Something happens that I can only describe as it seems to loose contact with water. The motor revs up until I back off the gas. Then it runs okay again. Any thoughts would help.
