Good afternoon. I purchased a 1990 Cherokee Sport Fisherman Hardtop late last year and I’m trying to find out what is the correct prop to run on it.
It’s an inboard with a 350. I know it’s left hand. The prop on it currently is a Chris Craft prop. I was told by my marina that the current prop on it is too small. I’ve been searching all over but I can’t seem to find out what prop it should be running.

Any help would be greatly appreciated. Thanks

Ayuh,..... Welcome Aboard,...... Answer these questions, 'n we'll see exactly which prop ya need,....
When posting a question about propellers, you cannot get a reasonable answer unless you provide the following information in your post: Items 1-4 are essential for meaningful response to most questions.
1) Performance issue you are trying to correct. Getting on plane and decent cruising speed
2) Current prop manufacturer, model, aluminum or stainless as a minimum. Chris craft bronze 727 LH
3) Current prop diameter and pitch (required). 13 12
4) Wide open throttle RPM and speed with an average load (very helpful) 6500 21mph
5) Engine/drive make, model, year, and HP Crusader 270 hp
6) Boat make model, year, length and weight Cherokee 1990 27’ 8000 lbs

I bought a mechanics tach and it was jumping all over the place. I had from 5000 to 7300.
