RE: [inboardhydros] Re: HP ratings for current 1.5L?

Hey Joe, all

Check out this little fella

I know it comes injected, but should be adaptable to carburators.

See anything (else) that wouldn’t meet rules?

Ralph out…

The R-1 engine is the same as the PWC Yamaha 140- 160 motor. A real nice motor BUT it had 5 valves per cylinder. The 140 motor work really work nice in a hydro. 4 into 2 into 1 exhaust wraps around the motor. Motor also turns 10,000 rpms it has a reduction gear in the ski to limit it to 7500. Plus it switches the rotation on the motor for the ski. As you can tell I've had the motor out of a ski and done some work on it. Very nice package BUt won't fit our rules as they are written.

I agree that it would be no problem to run the motor locked into a gear, but help me out here, if you could adjust the gearing to the prop rather than the prop to the motor, could you make the prop selection and performance as easy as a shift into a lower or higher gear. How much torq dose a 1.5L need typically? Head spinning must sit down.
