    I'm afraid the Charlie Strange's and Charlie Alexander's of the marine world are long gone. Some blame Charlie Strang for the demise of OMC. I guess in todays world ecomony the almighty $ is the most important thing. In my day, we sold in excess of 500K 10/15 hp outboards alone. Now that's the total marine market. I remember when Honda brought out thier 350cc 4 cylinder 4-cycle bike at a retail of $1395.00 I put it next to the OMC 15 hp at a $1295 retail and asked where was the value difference between the two. I also said if OMC didn't address the cost issue head on with vigor, the marine business would die. However, at the time OMC sold out every thing they could make for the model year by years end, starting in Sept. so nobody would listen.

    All the hardware that remained in the US, but fortunately, much of the V-6 and triple hardware was already in the hands of Cees Vander Velden in Holland. After his death, it was acquired by Seaway.
    Since 1925, about 150 different racing outboards have been made.

    This picture indicates just how much smaller the Rotary powerhead was when compared with a 1971 6hp Johnson/Evinrude or the earlier Johnson/Evinrude 9.5hp

    How did that carb work mounted sideways?
    ( I dont want to hear it was a rotary so centrifical force kept the fuel in the bowll)

    Default Sideways carb?

    My guess is the engines were tested horizontally in the prototype phase, ans that the image is rotated 90 degrees. The tip is what appears to be a starter pull on the end opposite the flywheel. Might this be a leftover from a snowmobile application that would have the PTO where the flywheel is?

    I think Tim is right ... look at it this way:

    The wires now seem to be hanging down naturally and the things now at the right appear to be parts bins with nuts and bolts in them

    I don't know what i am looking at in regards to 6HP powerheads, but I do know that is a belt driven torque converter as used in a snowmobile in the flywheel of the first motor. Are you sure these are outboards and not something that maybe was not intended for Cushman carts or Lawnboy mowers? The taper on op of the flywheel without the clutch is used for a belt as well.....The snowmobiles had fins over the end of the housing.

    Thank you Rotary John,

    This is one of the best posts I have ever read.. about the Outboard business
    going south..

    I had exactly the same feeling as an exclusive Evinrude dealer..
    and Waukegan was not listening to the dealers..

    I agree, I always asked why they didnt make Jet ski's as they will be big soon after seeing Kawasaki 440's start to turned up to our marina in Oz in the late 70's.
    Both Merc and OMC said there was no market and they will be banned soon?
