    Holes in J15RLCOB 15 HP carb chamber?

    I am rebuilding the carburetor from my 1985 15HP outboard. I keep it because it is the only motor that will fit through the cutout on the transom of my 1976 Catalina 27. While I was cleaning the body, I noticed little defects in the casting, in the floor of the chamber under the large...

    effect of larger spark plug gap

    I have 1985 Johnson Seahorse 15 long shaft J15RLCOB. After all the help (carb rebuild, ahem, twice) that I was generously given, here, last year it is running very nicely. Thank you. Last weekend, I started it up for the first time since it was professionally winterized and stored. Unlike...

    1985 Johnson 15 bogging and stalling after running fine

    I have a Johnson 15 hp J15RLCOB long shaft on my Catalina 27 sailboat. It has been great for the 4 years that I have owned it, with the exception that it will quit if you go from fast to idle too quickly. I learned to live with it. This season it has learned a new trick. It will start...

    1985 9.9hp 15hp Sailmaster - cannot remove carburetor

    Following suggestions from an earlier post, I am trying to rebuild the carburetor on my 15hp Johnson Sailmaster, J15RLCOB. My service manual has not arrived, yet, but I want to get going on this. But... I cannot figure out how to get a wrench on the port side nut that bolts the carb to the...

    J15RLCOB 15HP shuts off at idle throttle

    I'm sure that this has been gone over, but I could not find the information using search. I have a 1985 15HP Johnson J15RLCOB that I use as a kicker on my sailboat. I would really like to make the setup safer. Right now, the engine quits if I turn the tiller throttle to the minimum position...

    Johnson Sailmaster 15 won't start

    I have a 1985 Johnson 15HP Sailmaster J15RLCOB. No electric start, no alternator. Water pumps fine. Earlier this season, I had water in my fuel and had that problem professionally repaired. Ouch! For what Brewers charged, I could have almost bought a new motor. But it ran after that, twice...

    sailboat outboard steering lock?

    I have a J15RLCOB 15 HP outboard in a wet locker, or lazarette, in the stern of my Catalina 27 sailboat. Running with the outboard is a bit of a contortionist act, because of the locker hatch. I would really prefer to lock the outboard at 90 degrees to the transom and use the boat's rudder to...
