Re: 1995 four winns 210 horizon 5.0 volvo
What is the altitude in northern Utah? Is it similar to MI? Volvo has a "high altitude" gear ratio.
The pitch I would recommend is the one that allows the engine to operate within the recommended full throttle rpm range.
What is your full throttle rpm with the present prop?
If you don't have a prop, you can run your boat's weight, engine/drive info through one of the prop selectors and get an informed recommendation for prop size that fits your boat and operating situation.
Your boat's dry weight is 3170. The motor's WOT rpm range should be 4200-4600 rpm.
It appears that a good Volvo prop size might be a 15.5 X 15 or 15 X 17, depending upon your elevation.
