I just bought the 22' BW with whaler drive listed on this site a few weeks ago. It has twin 130 hp Yamaha's and seems to run well. The question I have is what kind of max rpms should I expect. It tops out at 6200, which I think is a little high. Does anyone know what size prop it should have?

The engine has a redline of 6000 rpm, with a 2:1 gear ratio. My guess would be a 19" prop, which should give you pretty close to 50mph.

Although not as powerful as the Merc V-6 135's, you might go to the on-line prop selector, using the 135 two stroke (has same gear ratio and red line of 5600) and see what you get. If you have to buy new props, give serious consideration to a set of Merc Laser II's for that boat.

Incidentally, twin 25" engines on a Whaler Drive should be lifted about 2" above the "all the way down" position.

It's good to see a lot of Whalers are changing hands from the "marketplace" section.

I just had the boat out. It ran 40 knots on the GPS with two people aboard and half of a tank of fuel. Does that sound about right??
