View Full Version : Prop

What diameter and pitch are you guys swinging on your 1998 Prostar 190. The prop I got with this boat seems a little small in diameter. I could only get a rough measurement across the nut and shaft but it looks to be around 11 inches. That seems a little small to me; maybe not. It's too cold to go and pull the prop to look at the markings. Maybe someone here can give me an idea of what you are using.:confused::confused:

A lot of variables in props, starting with the transmission if its a gear reduction or not and engine hp...

How is your performance, hole shot, top speed and rpm's

As for my TS190, 351w, 1:1, I'm running a 13x12 Acme CNC, awesome hole shot with ~47 mph top end @ 5000 rpm.

Duh!! Should have known.
5.7 Liter 350 cid 1:1 Hurth Trans. Wasn't able to get the boat wet to know top end speed or RPM's. Just kinda was looking for an idea of what some of you are using.
