I have a 1976 55 hp johnson on a 69 Mckee Craft 14 fiberglass trihull. I was given the boat and motor, as they were going to scrap it. I have not had it in the water yet. After 3 months of work on the hull and motor. It is getting close. Just need a few more things. Primarily a prop. The motor has an aluminum 12 1/4 x 15 with 13 spline but it is chipped and bent.
I can either get it repair or buy another prop. I ran across a used stainless I can get for cheap. The size on it is 12 1/2 x 13 with 13 splines. While it is one of the sizes listed that can be used with this motor. The part number on the prop is not the same as the one on the evinrude johnson outboard parts catalog for that size. For example the part number for that size listed for my motor is 0038682 however the number on the prop I am looking at is 390849. I assumed that because it has 13 splines it will work, but I know just only slightly more than jack $#*$ about props. I assume the change in size and pitch will give me different characteristics on the water than the current size I have, but since ive never had it in the water, I doubt I will notice a difference lol
