OMC 75 prop
So I was looking for something in the garage and on the shelf I found a prop I used to run in EP class in the early 80's. It was built for my 13 Critchfield with a 75 OMC by DAH, if I recall correctly that was Don Henrich. Any one use these now?

Is it 13 spline? Do you know the pitch/diameter?

I will post what information when I am down at the river. I know I can measure the diameter but to the best of my recollection the prop pitch was 21 before DAH started to work them. I dont know exactly what it ended up being. I believe it is still in its original OMC box I but right now I cant say for sure. This prop was used for circle racing so its gonna be a for acceleration, handling, and speed than just top speed.
Thanks.

I was mistaken. I had totally forgotten about this prop. It is NOT one of my old race props. It is a DAH 13x27 #386485 over the hub cleaver that I had build for my 140 OMC/Hydrostream Viper for running on the river.

I am located in Richmond and the prop is currently located near Burgess Va in the Northern Neck. I still go there almost every weekend even in winter. The prop has been sittin in the box since I sold the stream in the late 80s so I dont think there is much of a chance I will ever use it again.

I have been out of performance boating for a long time so I have no idea. This prop is quite a bit bigger than what I ran in EP which was something like 12 1/4 x 21-23. We had a minimum weight of 840lbs and ran only a couple of pounds over that but the 75s had to be pure stock.
