[QUOTE="RaisedByWolves, post: 472352, member: 22989"] New/used lower housing should be here tomorrow. \:D/ Now, having dug into the two lower units I have on hand (76 35hp and a 84 25hp)I find that the 35hp has a much higher gear ratio than my 25hp lower I have from a different busted duck motor. This means I absolutely HAVE to try this motor out to see what speed difference there will be. The stock prop for the 35 is 11 x 9 which would be a good starting point for a larger boat, but Im going to try it with one of the many 10 x 13 or even my 10 x 15 prop to see what she does. :mrgreen: I know the larger diameter prop would be more efficient, but until I find one......
