    1985 Johnson 115 hp Gear Problem!!

    I am working on a buddies engine. It's a 1985 Johnson 115hp, model J115TLCOS. This engine had been sitting for 2 or 3 years. He brought it to me for a tune up. I rebuilt both carbs, replaced the water pump, lower unit oil, and the spark plugs. It had a bad power pack, so I replaced that...

    Replacing OMC Ignition Switch

    I am in the process of replacing an engine on a friends pontoon. The pontoon now has an Evinrude 50hp and he bought a Johnson 115hp to replace it with. Both of these engines have the large red plug wiring harness. The difference, though is that the 50hp has the push-to-choke on the key, where...

    Johnson Tach Problem

    I installed a new tach on my boat, and it's not working correctly. I have searched the forums, but I haven't found exactly what I'm looking for. I have a 1998 Johnson 70hp. The wiring harness had the tach wires already attached. I went to Bass Pro and bought a new tach. I installed it...

    Water in Pontoons!

    I have a question about water in my tubes. My pontoon is an older boat that was completely refurbished last year. The tubes were gone over and no holes were found. The only problem was the drains on the back of the tubes (U shaped pontoons) looked worn. I replaced the drains and inserts with...

    Idle Speed on 70 hp Johnson

    I love these forums, they have been a tremendous help to me. I recently purchased a 1998 70hp Johnson and put on my pontoon. The engine starts easily and runs great. My problem is, it idles very high. I have tried adjusting the throttle cable and linkage on the engine, but it is still...

    Question About My Jackplate

    After reading many posts on here, I have not been able to find an answer to my question. I recently built a jackplate in my garage for my 24' pontoon. I mounted a 70hp Johnson long shaft on my boat. The transom had been modified in the past (before I owned it) for a short shaft engine, so...

    Replacing Pontoon Transom

    I am in the process of repowering my pontoon. I have a 24' toon. It had a 50hp Mercury, but I purchased a 70hp Johnson to replace it. When I pulled the old engine off, the transom board was pretty rough. I decided to go ahead and replace it. I used 2 pieces of exterior 3/4" ply bonded...

    Replacing Transom on Pontoon

    I recently purchased a 24' Playmate. It had been left outside and was in bad shape. My wife and I stripped it down to the toons, and completely rebuilt it. It had a blown 50hp Mercury. When I pulled it off, the transom was rotten. It was 2 pieces of 3/4" plywood. I have a 1998 Johnson 50hp...
