Title: Stock Ford 460 and a Berkeley Jetovator
Post by: GAWnCA on August 28, 2007, 02:41:15 AM

Can someone tell me with a stock Ford 460 and the Berkeley Jetovator, what the best operating RPM is and what speed I should expect?  Thanks, Greg

I have no idea what kind of boat you have but I will say this. A good strong stock Harmin Marine 460 will turn about 4600 with a Berk A impeller. Depending on the Boat your speed will change quite abit. In a light 18' lowprofile 62-68mph, ina 21 mini day anywhere from 53 - 58mph.

Thanks, I guess I should have stated that it's in a 1975 19' Miller Bubble Deck.  By the few replies that I have received over several forums, it's pretty much the same, 60+ between 4300 and 4800 RPM.
