Yamaha Pro V 150... whats so special about it and how do I break it in ?

[cee jay]

I live in Sri Lanka and I have just imported a fully rebuilt 1989 Yamaha Pro V 150 from USA.<br />What are the DOs and Don’ts during running in?<br />What is the duration of running in?<br />What should the oil : fuel ratio be during running in and what should it be after running in is complete? (The motor has originally had the precision blend oil injection system but it has been removed at some point)<br /><br />What does PRO V mean? What’s different about it compared to a regular Yamaha 150 of the same age?

25:1 during run in. (10-20 hours)<br />50:1 after run in.<br /><br />Low rpm for several hours, then short bursts of mid rpm. Finally, short bursts of high rpm.

the PRO means that the motor has power trim as well as tilt. non pros just have power tilt.
