the formula I own 1995 336SR1 has a notched transom, 336 was launched in 1993, notch added in 1995. it still has deep bravos and I understand the notch added a couple mph, my boat won powerboat mag offshore boat of the year in 95
but I am told this boat really performes with shortie drives ( for reasons mentioned by appsyscons and carcrash)

someday I will try imcos shorties and higher pitch props on 1.5 drives instead of my 1.36 drives

In 1995, your boat was likely set up with Mirage props. With the -2" lowers and Bravo 1 props, your speed should jump at both cruise and top end. Where would Formula set your X today? It might be more than +2". I also agree that you will like the 1.5 ratio.

He didn't say Reggie invented them. Just stated Fountain uses them.

Reggie doesn't notch transoms... he just extends the back above the running waterline so he can sell a 27 foot boat as a 35. next we will hear how the beak is aerodynamically designed and wind tunnel tested to provide a precise amount of aerodynamic bow lift.

Sorry........I should have just left it alone........:rolleyes:

That's awesome how that works out. Good looks and functionality.:drink:

It's funny how Reggie's big power race boats have 90% of the beak removed... must hurt performance rather than help around the race course.

Raybo is following the exact dimensions we put into the 21 Shadow after George re-designed the 21 Challenger. It worked in 1979....and it works today.

That hull will still run rings around anything made today.
