I just ran a 13x11 ACME 3 Blade Prop on my 1980 Ski Nautique (stock 13x13) with full ballast. What a hole shot, the boat is up and planning in no time at all. If you are considering an upgrade due to ballast in your boat, contact ACME Marine and reiview the specs of you boat with them. It's worth every penny you invest.

I just went from the stock 13x13 SS on my 1999 Malibu to an Acme 13x11.5 and I hear ya man...its amazing how much difference a prop can make! The 13x11.5 is the 525 which model is the 13x11?

It is the 911 - new model. I have sold 10 on the water right now.

Karl, isn't the 13x11 the 542? (cc=rh rotation) <BR> <BR>if not, what is the difference?

542 is 1 13x11.5

yeh, thats right. ok, but the 911 shows a 10.5 pitch for 1 1/8 LH rotation. That wouldn't fit an 80s nautique, would it? We're 1" RH. Just wondering if this is another 542 review or if there is a new prop out b/c I'm just about to buy a 542.

ya i gotta old sn to and the prop got slightly bent up last time i was on the water. is it worth the money to upgrade. and whats the effect of some small bentage

the 542 rocks!! i dont know about the 911. i would be willing to try it if it wasnt 4oo$

i went from a 13x13 to a 525 on my '01 'bu, i love it. 2100# of sacks and it get s out of the hole effortlessly. best purchase yet.

I have to agree.....re-propping your boat is the cheapest way to gain low end performance. I went with the 525 on my VLS Wakesetter after talking to the guys at ACME and I love the prop.

There is another number for the RH rotation.

I just ordered the 525 from ACME today. It should be delivered next week sometime so I'll let you know what I think after I have a chance to try it out.
