I recently had the Nizpro 332HO Performance Repower with the Yamaha stock 6200rpm rev limiter installed on my Yamaha F250s by Sage from Fathom Marine and I could not be more happier with the results.
Heading offshore any day before the tune with a head swell trim tabs buried, I was averaging 1.2 MPG.
With the tune, same conditions, I am now averaging 1.5 to 1.8 mpg. The better fuel economy is what I was after and for just a bonus, I also gained some top end speed.
So if you are looking for a tune to improve your fuel economy and add extra speed, do not hesitate to do it.
I run a Pursuit 28 foot center console offshore boat and believe me itโs heavy but since the tune it has made the boat a whole different machine .
Once I got the props dialed in and settled with a set of power tech four blades, that was the only change I had to make. Great work and thank you, Sage.๐ฅ
