Anyone out there with a 19SPX 4.5L 200HP running a High Five prop?

Mine came with a 3 blade 19P prop (I'm at altitiude - 5000' +) and was wondering how a High Five 19P might improve the hole shot and if the reduction in top speed is significant.

Any other prop swap experiences on this boat/power combo would be helpful too.

Thanks!
 
I put a four blade on 19 SPX with a 150 OB and it helped. Most noticeable was around the docks. It is hard to say if the 4 blade was the reason for a better low end improvement or if it was going down a pitch. I usually run the boat full of people doing water sports so I was looking for a better low end and gave up some top end. I have four blades on my bravo IIIs on my 340DA and they made a world of difference around the docks and cavitation in turns.
