This is running next to a Bullet bass boat not on GPS. Motor turning 5600RPM. This is a SRA I think. I will check and post. I know there are some hopped 3-Cylinder Yammys out there turning a 12-13 pitch wheel at 5600-6000RPM running in the 40's. A light boat 1544 with a 10" jack plate, with cavatation plate around 3/4"-1" above bottom of boat with a stock 3-cylinder yammy runs very well.

3 cylinder yamaha is 1.85 gear ratio. I used it on my suzuki to determine if my tach was accurate. |
