    which motor should I keep

    I have a 1980 mercury 50hp and a 1984 johnson 50hp? The johnson seems very simple to work on and the merc is a pain. The merc just seems to be a higher quality unit. Is the 4 cylinder more desirable than 2? Is this apples to oranges so to speak? What are the advantages or disadvantages to these...

    making a boat more friendly for disabled angler

    I have a 16ft alumacraft classic it's a great boat but it is getting harder for my elderly father in law to get in and out of it. He had a stroke and has a hard time with strength and balance. It's not a big boat and it also has a console so there is not a great deal of extra room on the deck...

    1984 50hp johnson running rough

    Motor swap

    I am going to put a 1984 Johnson 50 hp on boat in place of a 1987 Johnson 48 spl that has low compression on top cylinder. Will the electrical stuff plug in the same way? It looks like I'm going to have to wire battery ground, 12 v to starter and a plug. I noticed that OMC changed a lot of the...

    1987 48 spl has a knock or rattle?

    I have a 48 spl that is either knocking or rattling. You can hear it well at idle and a low speeds. I pulled the plugs and moved the cylinders to the top. When I push on them and they start to go down the flywheel spins with them right away. After seeing that I don't feel like it's piston slap...

    I know I should be adding this to my last thread , but I can't seem to get it to post. I blew a primary coil on my 25 hp johnson electric start (melted the points to) I suspected and it was confirmed by many users that 12 volts got up there. I was going over with a voltmeter tonight and seen my...

    1975 johnson 25hp keeps trashing primary

    I have a 1975 johnson outboard with electric start. I got hosed on an ebay deal and learned a lot (Don't buy from Rogers Marine in Wisconsin) The motor is electric start but did not have the boat side cable. Being an electronic tech I had no problem grabbing a clymers and wiring a new ignition...

    1987 Johnson 48 Spl Hard To Start

    Hello, I have a 48 spl that is hard to start. Pulled and cleaned the carbs they look good. Plugs are new and gapped. Timing is right on. When it does finally start it idles poorly. When I get it in gear it pushes an Alumacraft 16 ft classic about 30 mph. I have noticed an orange lever on what I...
