View Full Version : What is the best prop choice?
09-03-2009, 02:59 PM
Need some help here from all you experts.
I have a 94 MC PS205 with the Indmar350 Chevy, 275 Horsepower with a 1 to 1 ratio transmission. I have a 3 blade prop which I think is the stock prop for the boat.
I have been toying with getting a new 4 blade prop and have a few questions:
1. Will it provide a noticable increase in torque?
2. How much top speed will I loose being my current top speed is ~43 mph
3. What is the best 4 blade prop for this boat?

I switched from the stock 4 blade to an OJ XMP 4 blade and it increased my low end, no sacrifice in top speed, and the prop is smoother. Talk to Eric at OJ and he will tell you the right prop.

You can look at ETS report on OJ vs ACME as well think he had the same boat

Go directly to the man that knows, Eric Johnson @ http://www.ojprops.com/contact_us or contact him by pm, EJ OJPROP, http://www.mastercraft.com/teamtalk/member.php?u=1537
Be prepared to give him any info he may need like, current prop info off the hub, baseline numbers of the speeds and RPM's for the current prop, boat model and year, engine size, transmission ratio, function (skiing, barefooting, surfing, boarding, tubing, etc.), ballast use, fuel load, gear, nominal # of passengers, etc. He will need it to determine the best prop for your application.

I happen to have arguably the best prop for that boat for sale in the Marketplace!
ACME 543 13x11.5 3 blade. That or the similar version of the OJ prop.
Shoot me a msg or call 970-319-0630
Compared to the stock 13x13 cup prop, waaay better hole shot, no rpm loss at altitude, doesn't overrev at low altitude, top speed before and after on my 190 = 44mph (+/-1) with gps.
Will yank your arms off coming out of the water.

I have the same boat and installed the ACME 541. Better hole shot than the stock prop. Great for skiing. If you are going to run with ballast I'd go with a lower pitch like the 543 or a 4 blade. One of my skiing buddies is rather large and the 543 would actually work better for pulling him out.

Thanks for all the input here. We'll see how it goes.
