    Recently bought this 89 70hp Yamaha motor. The previous owner said the water pump needed to be replaced. The engine started right up and sounded good. Only ran it for about 30 seconds. Prior to starting I did a compression check which was good the plugs were clean and there was no discoloration...

    Can anyone tell me what the tube with the knurled knob just below the shifter is and where it goes to, up on the engine.? I bought a motor that the threads that the knob connects to are broken off and it looks like the metal part with the threads is just a dead end. I can't see where it goes to...

    Recently purchased a 1989 70hp Yamaha that the trim/tilt was not working on. The previous owner had been raising the motor by hand for the last part of the fishing season. The motor was in the raised position with the stops locked. I filled the reservoir with AT fluid. The bottom rams are all of...

    Bait and Livewell

    I really don't know where to ask this. I have a 97 Crestliner 1650 Sportfish with a baitwell and livewell. The switch for the wells has a setting for baitwell, Livewell and both. There is a pump in the splashwell that powers on in the baitwell position but I have no idea where the Livewell pump...

    97 90Hp Johnson trim tilt

    I have a 1997 90hp Johnson motor that when it is hot outside and it is in the down position I can raise it but then it won't go back down. It happened one day last year and now yesterday it did it again. I just checked it this morning and it worked fine, both up and down. My thinking is that it...

    Shifter on 97 Crestliner with a 97 90hp Johnson

    A couple of weeks ago I had a friend show me how to press the center button on the shifter that allows you to keep the prop disengaged but the shifter set to a higher idle speed for easier starts when it is cold. Last week I took my boat out again and tried to use that feature but it would not...

    97 Johnson 90hp won't lower

    I raised my 97 90hp Johnson motor to work on the lights on my trailer and now it won't lower back down to the run position. It acts like it is hitting a stop of some kind. I raised it to the max to give myself more room to work and now it will not go back down. I'm at a loss:(

    Minn Kota Ulterra manual stow

    Yesterday I had to do a manual stow on my Ulterra. Does it now have to be taken to a repair shop to have the worm gear tilt bracket and the manual tilt knob bracket put back in sync? The motor and deploy feature is working fine and it was just a stupid mistake of mine that caused me to have to...

    1997 Johnson Mod: J90TSLEUA

    Just bought a different boat with a 1997 90hp Johnson and I'm looking for a service manual for it. It appears there are a couple of different manuals, one for 60 degree motor and another for 90 degree. This is my first experience with Johnson and I'm not sure what the difference is. Another...

    I have a 2000 Sylvan 1600 Expedition DC that I purchased last fall and I want to upgrade the fish finder but I can't figure out how to run the cables from the finder to the transom.

    Jet unit

    Thinking about putting a jet unit on my 1989 100hp Mariner motor. The boat is a 1968 aluminum deep V Crestliner. Can you put a jet unit on just any boat or is there bottom designs that work better than others? What controls would I need in addition to the jet unit. Is there any changes or...
