Propping my 300PM Starflight???

[jrumon]

OK gang... looking for input or opinions on what some of my props will do on my 21 Starflight 300PM project. I have several props to play with and thought I throw out this topic for some "bench racing" so to speak. Here's the set-up:
1992 21' Starflight...(does pink stripes make it faster?)
1999 300 Promax, offshore mid, updated 2000 ecu & coil packs, 6400 rev limiter, and has 1.75 ratio Sportmaster lower unit.
CMC 10" hyd. jackplate with dial-height & gauge.

I have 8 MERC props to play with so far:
(all 100% stock and mint)
24p Revolution-4
25p Tempest Plus
25p Mirage
26p Chopper
26p Chopper II
26p ET
27p Lazer II
28p Chopper

?Any guess on how any or all of them will run???
(RPM, MPH, motor heights, trims, etc)???
?Any plus or minus's to any of these props???
?Any other prop recommendations???

It's ALMOST time for CHECKMATE season... http://www.checkmate-boats.com/infopop/emoticons/icon_biggrin.gif Jim

Its going to be close but I would say the ET or the laser to start.
The 28 chopper will be a bear to get out of the hole.

Top speed I'll guess the Chopper II or the Tempest Plus or the ET. Be fun trying eh? http://www.checkmate-boats.com/graemlins/thumb.gif

Ill bet that tempest will be nice but I think 25 isnt enough pitch.Cant wait to hear your #s Jim!

[jrumon]

I'm still looking for some bigger pitch props... with the 1.75 ratio, I'm thinking 27-30p range, but we'll see. I can always swap in a set of 1.62 gears I guess???

Anyone know any pro's or cons of the large and small hub trophy's???

Difference between the 27p LaserII and a 27p Tempest Plus???
