Engine RPM's

Are our M35B Universals governed at a certain RPM level that can't be exceeded?  What is the maximum RPM level of our engines?

The universal M35b specs show a Max RPM of 3000 given that the correct propeller is used. Our 1998 M35b currently tops out at 2800 RPM. It has the factory installed 3 Blade propeller. Many vessels apparently had original 2 blade props, So I think that the question should be: What is your top RPM and what type of propeller do you have? Also the RPM guages are not always calibrated correctly at the factory (said my mechanic). so he calibrated our guage to read 2800 at full throttle.

It's easy to calibrate the tach. Just a small screwdriver adjustment in the back of the tach.  I believe an optical tach is available to members to borrow. I bought a cheep Harbor Freight unit.  I did paint my front pulley flat black to get better readings.  Be sure and check at several RPM's. My tach is so old the adjustment pot in the tach is flakey so I use my I70 to display engine vitals.
