What props have you had on your boat and how have they performed???
I'll start with props that I have had on my 2005 SV211 V-drive powered by the Excalibur 330HP GM 350, my boat has full ballast tanks and I usually add more weight.
1) Acme 380 - 13.5 x 17.5 Boat performed reasonably well with a very light boat crew, no ballast, and low fuel level. As soon as you added weight the boat was unacceptably slow out of the hole.
2) Modified Acme 380 - 13.5 x 16.5 with heavy cup, stock sport prop repitched by Pitchometer Props in Alameda, CA.
The modification destroyed the prop, sounded like the prop created turbulence under the boat, limited improvement in acceleration out of the hole.
3) Acme 536 - 13.5 x 16
Better out of the hole but still not as strong as I wanted, top end dropped from 45mph to 43mph with speakers and bimini up.
4) Acme 644 13.25 x 16 (stock team edition prop)
Good holeshot, top end down to 42mph or less depending on load. Seems to lose top end more when barefooting when using this prop.
5) Acme 1160 13.5 x 16 (same dimensions as the 536 but slightly more cup)
This prop was chosen in an attempt to gain some some of the top end back for barefooting. It does seem to work a bit better when the boat is lightly loaded but it is definately slower out of the hole than the 644, very close in performance to the 536 but runs maybe 1-2mph faster on top depending on load in the boat.
5) OJ 13.7 x 15.5 XMP
I had high expectations for this prop. Unfortunately it did not have the holeshot nor the top end of the Acme 644, was closer to the 536 slower top end than the 1160. I found this quite bothersome so I took several measurements. The blades of the OJ where substantially thicker than the Acme. The OJ blades were 0.150 and 0.183" thick near the leading edge and near the center of the blade. The Acme blades were 0.105 and 0.150" thick in the same locations where measurements were taken on the OJ. I can only speculate the Acme either flexes under acceleration or it's thinner profile allow it to perform a tad better than the OJ. It is interesting to note that the OJ should be much less susceptible to damage from light debris in the water, possibly 25-40% stronger than the Acme.
6) Acme 1272 14.5x14.25 (deeply cupped)
This was going to be my high torque prop but I found that it did not perform significantly better than the Acme 644 so I returned it for a 1234.
7) Acme 1234 14.5x14.25 (standard cup)
This prop is a good wakeboarding/wakesurfing prop. It is the strongest prop out of the hole when compared to all others. Unfortunately the top end is all the way down to 40mph with a light load and 38+/- for barefooting. It really pushes the motor into the higher rpm ranges for slalom skiing. i am not that comfortable pushing the motor that hard that often. The biggest unexpected realization from this prop was the golf ball sized water pellets it throws at skiers running 28off/34mph (that's me). Getting pelted in the midsection with these large water pellets in the midsection while skiing was no fun. Since I didn't want to start skiing with a cup, I traded this prop for an Acme 856 from a fellow Planet Nautiquer.
8) Acme 856 to be tested soon.
I will likely return to the Acme 644 as my normal prop. I will probably keep the 1160 as my backup and the 856 as a high altitude/heavy crew prop. Some motor modifications, possibly a supercharger or otherwise, are likely to be my boat's future. I expect the 1160 would be a great all around prop if I could get over 400 foot pounds out of my motor (over 350lbs at 3000rpm).
