    Does this chart also work in reverse? ie: are the powerheads for these interchangeable??

    I have an '86 60 hp Evinrude that the powerhead threw a rod, and I am wanting to know what powerheads will fit? (even if I have to do modifications)

    I don't see anything for a 93 Johnson 150 fast strike, or maybe I'm just reading it incorrectly.

    In need of new lu asap...can anyone tell me what lower units will fit this motor. It's a 20" shaft, 15 spline on the prop, 20 spline on the drive. I believe the gears are 1.86 (24:16). Will any of the v4 cases fit, or just the v6? If so what hp and years are compatible?

    I have a 1975 135 hp V4. So will the later lower units shown in the chart for cross flow V4's fit this motor?

    this is telling me that the fast strike- and intruder 150 and 175s in 93-95 are the only ones similar,

    but they also list a lower unit for your motor that fits all V6s in the 93-95 range...

    they dont explain the differences, but they both are on your motors parts list

    The lower units from the 1973 through 1976 135, and the lower units from the 1973 through 1977 115 and 85 will all work on the 1975 135.

    The gear ratio is slightly different between the 135 and other V4 drives in those years, but not enough to require different propellers.

    Bolting up the wrong LU with no attention to gear ratio spawns nightmares like this. http://forums.iboats.com/johnson-evinrude-outboards/1990-evinrude-120-4600rpm-wot-enough-428262.html
    Be careful I spent lots of money to educate myself in regards to my engine. I currently own BOTH 20" and 25" 140 V4 (Small Bore Looper) 1987 and its 13 spline not 15 splines.
    Just verify your gear ratio before and after you swap and you never regret it.

    I just finished bolting up a complete lower unit from a 1979 Evinrude 50 to a 1984 Evinrude Super 55 because the original drive shaft was sheared below the water pump. Everything matched up and operationally checked out good. The lower inside exhaust housings looked a little different but the 1984 matched up to the 1979 just fine. Both of these gear cases had the large diameter (4-1/16th inch) hub.

    I know this is an old thread but I am having lower unit issues. Will a type M replace a type O on a Johnson 250 ocean pro ? Is the "M" or Magnum a heavy duty version? I need heavy duty apparently

    go to ***************** < or another site that sells these parts >..look up what you have and what you need with parts no.'s....the same parts no. from another year should be the same...also..in the Top Secret Files is a list of salvage yards which can be a great source of used parts
