Yamaha F150 question

[TheSilverFox]

Any of you guys running this motor? If so, can you share the info on the boat and prop you're running along with rpm and mph? I don't have an Xpress but I'm running this motor on a mod v boat and I'm thinking I need a different prop. Thanks

I have a F150 but cannot be of much help to you. Mine is on a Bennington 24 ft friction boat and I am getting 40 mph @ 6000 rpms with a Reliance 15 pitch prop. The Reliance is comparable to the Merc Enertia prop and it was made for the F150's.

I do know that the rev limited kicks in at 6300 rpm and it is best to prop it forma max. 6000 rpms. My motor is now 5 years old and has been flawless.

Thanks. I'm running it on a 20' aluminum and turning a 19T 15 1/4 Yamaha Saltwater Series II. I can turn it up over 6000 but I'm not really gaining and mph after 5800 or so.

Thanks. That's where I am too. 5800 at 50mph.
