They just did mine, gained 200 rpm and lost 2 mph

Isn't always an exact science Butch. Call Brett up, he will make it right.

Jason Saris, from Harbor 1.

I have not had the same experience.

I can tell you, as a full time sponsor of Team Saris, Brett and crew are a lot of the reason we have had the success we have over the past few seasons. More than once he has sent us a prop (or props for the new boat) that we didn't get a chance to test, when the green flag dropped, we were hooked up and out front. We also recommend BBlades to all our customers. It isn't an exact science, sometimes a second try is required, but very rarely and Brett always makes good on it.
