Wow, can't deny those results! More prop and it sounds like you'll net more speed. !

those results sound great, but i wonder what the boat would have run if it was propped right from the beginning. 4400 is WAY underpropped

recomended RPM for a 375 HP Volvo is 4600
due to full fuel tank and three persons on board
just 200 RPM below this is o.k.

there are also not so many props available for the Volvo Duoprop compared to Mercruiser Bravo 1 - so getting exactly to the right RPM is a little more difficult

Re: Raylar Results

Alfred:

As usual my Awesome German Dealer comes through with another winner! I heard your customer is so happy he calls you almost every day now just to talk about the boat. I am excited to see what the final result is with a little more prop tweaking! Can't wait until your Donzi dealer in Holland gets his new Raylar HO600 motor in a week or so, that should be very exciting too! I am trying to attach the new 496MAG (before) and the HO600 (after) pictures that will be on the website next week. I will mail you a disk in any event.
Again, congratulations to you and your customer on a beautiful job and great results.

Best Regards,

Ray @ Raylar
