Which prop comes from the factory on a 1999 Prostar 205. Also, if I get a second prop should I get the same factory prop. The boat has a tower and we use it 70% of the time for skiing and 30% for wakeboarding. Any help is appreciated.

Thanks
Mark

what engine / tranny do you have?


Here is the 2000 owners manual ... http://www.mastercraft.com/manuals/2000_OwnersManual-PS190-PS195-PS205-PS205V-XStar-X5-Hang10-Sportstar19-SammyDuvall.pdf it shows 2 different props on the 205 (around page 70 or so)

We have the one to one tranny and the engine is the 330 horsepower Northstar engine. This boat does not have the power slot.

Thanks

Most likely the 13x13 Nibral OJ Force (four blade).

FWIW, my 99 X-Star has an OJ 14x18 4 blade on it. I'm looking to swap it out soon for a non stainless steel version.

If it has a 14x18 on it, that's not a 1:1 transmission. Probably 1.5:1 to turn that big wheel.

I just found out from my dealer that Master craft recommends a 12.5 x 12 1 inch bore. Does anyone know if it would be good or bad to put a 13 x 13 1 inch bore on this 205 Prostar (330HP with 1-1 tranny).

The reason MC is recommending that is because that is what OJ recommends in the new XMP props. OJ supplies the props for new MCs. The XMP didn't exist in 99. Your boat came stock with a hand finished OJ 13x13 four blade.

When my father-in-law damaged his stock OJ 13x13 (98 PS 205) beyond repair, he got a new OJ XMP four blade (you guessed it 12.5x12).

If it's a hand finished prop, you'll be fine with 13x13. If it's CNC machine finished, dimensions vary, i.e., a 13x12 or 13x11.5 3 blade would work. Call Eric @ OJ or Bill at Acme. They are happy to recommend the best prop for you based on what your primary use of the boat is.

If you're 1:1, you have a 1" keyed shaft (I'm 99% positive they were still keyed in 1999).

Thanks for all your help with my prop questions. I am going to call OJ and then order the prop.
Thanks Again!!
