Hi, undergoing winter project of going through my MC. Dual batteries, stereo, buff / detail, steering, rudder O rings, shaft alignment / new packing, etc, etc..

Info here is great btw,.However, I cant open the link in FAQ about prop test sooo...

I have a 1992 MC Prostar 205, 285 HO. No clue what type 3 blade i have currently, most likely its the factory prop. I have dug through some archived discussions but a tad confused.... if i understand correctly...

ACME seems to be the choice prop.
- the 4 blade ##? gets better fuel milage, less top end (~1mph), improved wake for skiers, but much better hole shot?

- the 3 blade 541? increased top end (~1-2mph), increased hole shot (over stock), better fuel mileage, improved wake for skiers?

Do i understand that the 3 blade wins overall and the 4 blade is just as good but slightly less top end? Can someone help me assess the differences between these two. I see a win / win unless top speed is important(3) vice hole shot(4)?

Thanks,
TT Newbie

I have the ACME 541 on my '99 205. It is a fantastic prop and I love the performance in all respects but one. To me it puts out a slightly taller wake at skiing speeds than my stock 4 blade. Hole shot, top end speed and holding a constant speed are all superb though. I am still trying to figure out if I can have it all with another prop.

I have the 541 on my 94 205 and love it.

For those running the 13 X 12 Acme I would suggest our OJ 13 X 11.5 XMP 3-blade or OJ 12.5 X 12 XMP 4-blade. To compare the two brands you will have to use a 1/2" less pitch in our 3-blade.

Russlars - The offer to try the 13 X 11.5 is still on the table. Lets see if the OJ XMP 3-blade cures the wake.

Eric,
I will probably take you up on that offer once the weather improves and I can get the boat out and give it a true test.

I'm not sure what kind of prop I'm running now. I can't tell without taking the cotter pin out and Jesus Nut off. Any ideas for a 2001 X-5 with the 310 HP Predator engine? I'd like to pick up a spare.

1:1 transmission or Power Slot?

1:1, it's got a 4 blade prop on it currently.

I'd give the 13 X 11 LC 1" XMP 3-blade a try.

Eric, what would be the difference between those two OJ props? We are looking for a prop this year for basically the same boat... (P/S 205, 351/285 hp, 1:1)

What kind of changes do you think I would see with that?

If you have a old 4 blade and move into a CNC'd you will feel like you have a new boat

So, my payments would go through the roof and I'd have that new boat smell? ;)

You should see a little more, 1-2, MPH from the 3-blade with the same or better low end as the 4-blade.

As I said, the 3-blades are little faster than 4-blades. With the larger blade area 3-blades you should not lose anything on the low end.
