Re: Mercury 650
Hey Woohoo,<br />First of all...what year is your 650? I have a 1964 and we ski and tube with it regularly. Mine runs well and I think it is going to last a long time. I believe if it is an earlier model the controls are on the outside of the motor and as you get into the seventies they go internal or under the cover. The shifter shaft rotates the same way for both vintages but the cables move in opposite directions to obtain the same result. That would be what I would watch out for.
