I am so glad I find this site on the web. It's going to be very nice to be able to help and get help on the Mariah boats.
last fell I purchased a 1997 Z192 with a 4.3/V6. I only had it out a couple of times before the season ended and really do enjoy it. I did nictice that it would take a long time for the boat to plane out on take off, so this winter I pulled the prop off to see what pitch it was and found out that the old owner put an after market prop on the boat with no markings. I am reaching out to see what tpye of props members are running on this model boat.

Absolutely no markings on the inside of the hub? Oh well, a 19" pitch prop will suit your needs.

Thanks Mikeyt, not one marking any where, I even took it to a dealer as I thought I was going nuts not being able to find it. Would you go with a stainless steel or aluminum?

Depends if you boat in a lake/river etc that has underwater objects (dead heads, rocks) that you might hit if not carefull. If so, go with aluminum since they are easier to repair & less expensive to replace. The performance difference between an SS prop and a similar aluminum prop is generally small.

If you take the propeller to a prop shop he can tell you what the pitch is even if there are no markings. Before you buy another prop you must consider several things. If you know from last year what were the maximum rpms trimmed out? How long did it take to come out of the water? Are you going to have a lot of people, use it for mainly tubing, skiing or cruising. If you have a good prop shop in your area sometimes they will give you test props as I use to at my shop.
