Well Here are todays results with a 27 P-5 LH. (Drove Boat in Reverse)
3500 RPM - 44 mph
4000 RPM - 54 mph
4500 RPM - 64 mph
4900 RPM - 70 mph all GPS
It handled way better than the 28 B1, came out of the hole better, and had better midrange. It still Spun out Bad out of the gate..
It's got a appt. tomm at 9am to get a 1" drive spacer installed. Does everyone kinda agree with that? Then try the B1 28 again?
Thanks Derek

Hi Derek,
I guess that shows even a LH 5 blade works better than a RH 4 blade at the elevated stock XD on these boats. Wait until you try a RH 5. Yes do the spacer. It will definitely make your boat perform better in all aspects.
When you settle on your props, some extra cup, particularly on 4 blades will also help with your slip %s.

Steve

Well FINALLY got the spacer on and tested this weekend. Here's how it went....
1" spacer - B1 28 - 5400 RPM - 70mph same conditions and fuel
The boat still spins out really bad out of the hole, the nose goes way up, and it is sluggish in the midrange. Anyone got any suggestions? Thought maybe a B1 30"? I'm at the end of my rope! I got outrun by a baja this weekend This has gone to far!! LOL!!

Spinning a Bravo 28 to 5400 rpm and only going 70 mph... something is wrong! That is near 24% slip.
Either that is a really screwed up prop, or your data aquisition is incorrect. (ie tach or speedo.)
When my boat was stock, (600sci), I spun a Bravo 28 to 5300 rpm and the boat ran 80 mph on GPS with a 1 inch spacer.
For that mater, I have never seen a Heat run slip numbers that high... even with a 3.5" prop depth and a 3 bladed prop.
I am not trying to be rude or harsh... just pointing out that this does not make sense.

So, I took the 27 P-5 LH with me, stuck it in reverse and hauled ass!! 2000 rpm it spins to 4500 insantly and blows out. That prop only ran 65 at 4600 rpm.
Then I put the B1 28 that I tested with last time and it ran the same as the first B1 28. is a 30 to big? I have a 32 that came with the motor package that I thought was a complete waste of time and now I am wondering?
Any help is a appreciated!!

I just put a 26 PX5 Hydromotive on mine and I hit 75MPH GPS at 5280/5320 RPM I also have the 1 inch spacer on mine ...My Boat is a 05 Heat with a 525 ...I was alone in the Boat with a full load of fuel and Bow Cover on (Remember your Bow cover on should gain you a mile or 2 per hour)....
Now I did all that testing on Saturday .....On sunday I did it again I could not get it over 72/73 MPH .....I am thinking water was rougher on Saturday....
I am at Aproxx 1000 Foot Elevation
I will say this though ...That PX5 Really hooks up in turns and stuff ...
