    Lower unit compatibility

    I'm in need of a replacement lower unit for my 1970 Johnson 85 horse. I found someone who has a 1972 Johnson 100 horse. Both of these lowers are electric shift. Will this lower unit fit? Does anyone know if the drive shaft mates up the same? Thanks a lot. Paul

    1970 85hp lower unit rebuild

    Will the clutch dog and reverse gear from a 1971 85hp work on the prop shaft of a 1970? The shaft model number from those two years is different. Thanks.

    Sport Jet / M2 ???

    I own a Seadoo Boat with a Mercury 210 M2 Jet Drive. I've heard people call this set up a Sport Jet but it doesn't call it that anywhere in manual. Is there a difference between the M2 and the Sport Jet?

    Mixing Fuel and Oil

    I've been thinking about removing the oil injection on a Mercury 210 M2 Jet. Does anyone have any suggestions for easy ways to premix the oil and fuel before putting it into the 40 gal. tank that is on the boat? I can't just pour the oil in after filling up unless the tank is nearly empty before...

    Information about mercruiser engine

    I've been looking at a 2001 SeaDoo Challenger 180 with a 210 Mercruiser and M2 jet drive. Is this motor a 4.3L? Is it fuel injected? Is this motor proven and reliable? I recently injured my leg and can't get in there to take a look. Thanks

    Fuel Line I.D.

    I have a 1970 85 horse Johnson. I wanted to replace my fuel line and primer bulb. There are assemblies out there with a 5/16" and 3/8" inside diameter on the hose. Which would be correct for my motor? The line I have now is 5/16" and seems to run fine. Thanks

    I have a 1970 Johnson 85 HP. Model # 85ESL70B. This will be the third time I have taken the lower unit off and just can't seem to get it right. On the first two attempts when I used muffs I got flow after the t-stats open. I felt warm water from my tell tale, the ports on the back, and from...

    Water Flow

    I just bought a boat at the end of last summer. Had it out a couple of times without any overheat issues. I have a 1970 Johnson 85. I just installed a tell tale indicator using posts from this forum. I put the lower unit in a large tub, filled with water, (made sure water was above intakes) and...

    Wet Transom

    I bought a 15ft fiberglass V hull with a 85 hp outboard in mid august and only got it in the water once so far. (Other things going on) The boat seemed in great shape. I read a thread about someone doing a restoration and he had complained about the former owner of his boat not sealing holes in...
