Original Prop dimensions for ski nautique 194

[petteralexanderson]

Hi all,

I need a new prop for my 1994 ski nautique pro boss h.o. (carbed one) but unfortunately I cant find the prop specs on the existing one. Thus I wonder if any of you guys knows the original diameter and pitch when I look for a replacement prop.

We are pulling mostly slalom water ski and take occasional family day tours with the SN, so if you can recommend a prop I would be very grateful!

I believe OEM was a 13x16 OJ.

I have two of the "13x16" OJ propellers. They are actually 12 inches in diameter, in spite of the marking on the propeller.

Thanks guys. i have found a 13x16 OJ that seems in a good condition, will try to fit this weekend. Any other prop recommendations?

We had a 1990 Ski Nautique with the 351w 240hp and LOVED the 4-blade ACME 654 (12.5X15 .105 cup). Another great prop is the 3-blade ACME 1442 (12.5X15 .090 cup)

And as always the 4-blade ACME 422 (12.5X15.5 .105 cup) is nice too.

Thanks, actually I have no idea what the cup measure stands for. A quick explanation, someone :-) ?

The edge of each blade has a fold to it forming more of a mickey mouse ear than a blade. Cuppind adds to the pitch....maybe by an inch or two depending on prop size and cup.

Big thanks, ya'll.
