Hello all, I am long time river guy and just switched from a 25 foot 496HO V bottom to a deck and need some prop help. I now have a 28 Magic Deck with an Ilmor 625 and XR drive. Current prop is a Bravo 1 4 blade 24p. The boat was maxed this weekend, full tanks, gear and 10 people. I was maxing my RPMs at about 5K and MPH was low 60's. It came out of the whole quickly however I would like more RPMs and of course top end MPH without losing too much on the lower end. Does anyone have this set up and what type of prop, RPM's and MPH are you seeing? Thanks in advance for your help and input.

When you say maxing out at 5k rpm. Do mean that is all you could get out or that is as much as you pushed it?

I was maxing out at 5K RPM WOT. I did have a full load and it was really hot last weekend (115). I've been told a 24p is the best and I have also been told to go to a 22P or a 26p. Thanks

What year is your boat and who rigged it ?
I sold some Iimors with 625 and they ran low 80.
When I worked at Magic Corona ca.


I owned a 2004 magic Deck with 525 , GPS 80 WITH 26

I would agree on the 24 being perfect.

Taking into account the full load and the heat the 22 would be right for the circumstances.

I think the P5X's work well on the Magics. Have to see if someone else knows.

Whats redline on that motor?
I run a 24 on my nordic deck in the hot summer and/or with bigger loads and a 26 when temps get cooler. Merc 520.
Big load and WOT the 24 manages ~50mph at about 4800rpm, not enough umpf in motor to get to limiter.
Light load it'll turn about 5100rpm and ~64mph.
