180 Sportsman - F150 question

[Greg B]

Just finishing up my boat and need to make sure I have the right prop as the engine was on a different boat, though about the same weight. I'll check the pitch but its a black Yamaha SS prop.

Anyone have an F150 on a Sportsman? If so, what pitch prop do you have?

Thanks
Greg

Thanks! I looked at the Yamaha website and figured they were the same. Yamaha only showed the 150 HPDI unless I selected the wrong tab.

48 mph, alright! I might hit 40 now with my Islander now that I upgraded to a Suzuki 300.
