What prop do I have/need? pic inside

[Slicktified]

I own a 75 Slickcraft ss-194 with a 188hp Mercruiser 888, 17 feet, v-hull, guessing weight around 2900 pounds. The prop is beat-up and I'd like to get a new one. Also according to the tach I'm turning 5300 rpm WOT and 43 MPH on the speedo (no gps yet). The service manual states max rpm at wot should be 3800-4200 rpm, so I'm WAY over that.

Looking for a prop for general cruising, pulling tubes, skiers, wakeboards & etc. Kind of leaning towards a 4-blade prop for the smoothness(what I've read) Any suggestions on Dia and pitch?

Anyway the only markings on the prop that I see are a set of numbers on the hub between each blade. The diameter with a tape measure looks to be 14", 3-blade. Can anyone ID this prop? I photo-chopped the 3-sets of numbers into 1 pic.


Thanks in advance.

Are there any numbers under the prop nut?
I only find a ss 194 in 76 and 18' about 2,200 lbs.

I have not removed the nut, but I can't see any numbers at the edge like I've seen on other props.

I took out the tape measure tonight, it measures 17'-6". I weighed it the other day, with a single axle Yacht Club trailer its 3400 pounds.

Maybe the numbers on the prop are from if it was rebuilt at some point in its life??

Without the prop size you really can't make any conclusions.
I would think the boat would run about 50 or more.A beat up prop can have high slip numbers causing high rpm and low speed. A propshop can measure it for you.
They can also repair it so you could get some accurate numbers.
