FOUR STROKE 150 HP DATA

[sailboat]

-V-21, 1993
-Ran the Yamaha 150 HP Four Stroke for the first time this afternoon. 1 hour on it so it will loosen up a lot.
-The following data applies:
-- 4000 RPM 40 MPH (MPH is GPS WAAS, no current)
-- 4600 RPM 46 MPH
-- 56OO RPM 45 MPH (wide open throttle)
-Red Line RPM is 6000. I will be putting another prop on her next week and see if more RPM helps or hurts me.

-Only ran WOT for 45 seconds because of break in rules, but she is strong.

-One quiet engine with the little splash platform in to hold out noise.

-4000 RPM should be about 6.5 GPH. As soon as I get it broken in I will have the boys hook up the lap top to her and I can report real fuel useage.
