New Twin Yamaha F250 4.2L

Had a chance to test our the new twin F250 4.2L engines yesterday. Was very happy with the power and speed of these new engines. I previously had 2004 F225 which had to be replaced because of the infamous exhaust corrosion issue which had also spread to my power heads. WOT throttle gave 4900 RPM and a top speed of 51 MPH with 4 adults and 3 golden retrievers and 2 full tanks of gas. 51 MPH on a Sailfish is screaming! Lots more mid range power from the F250's too! Big investment but great engines.

I think the WOT is spec'd at 5500 RPMs. I am still using my props from F225s - the new props from Yamaha are back ordered. Can't figure how an outboard manufacturer can run out of props in May? Kind of like McDonalds running our of burgers . They are supposed to be in-stock mid to late June.

I repowered my 2006 282 last August. Only difference is going from 3.3L F250's to the 4.2L. To keep costs down I opted not to go with the fly by wire controls which made the repower very simple. I have been running my old props while waiting on my new ones (yes, they have been backordered since last August). I have only been able to get 5400rpms at WOT, I am hoping to see at least a 400 rpm gain with the new props. We shall see.
Good luck with your engines, you will love them.

We did the same, stayed with mechanical controls, I think the quote on the wire controls was 12K higher than the mechanical.
