    ProTester prop?

    hello all, Newbie here.. Ive just recently got my boat in the water. I bought a 94 hydra sports ls175 with no motor and installed my 1985 XR2 merc on it. I had to redo all the wiring etc on the boat and am just now getting down to testing and tuning. The prop in question is a "ProTester" stainless prop and is a 24 pitch (stamped 24 on it) There are no other part numbers. I have tried searching and have come up with a few hits but nothing about performance. The truth is its probably circa 1985 or so and no one will have much info. I need a prop recommendation but I honestly dont have enough information to ask yet. Im not 100 percent my tach on the boat is accurate as it was hooked to a Evinrude 150. Im not certain the pole positions on the tach are the same for the merc. The boat was ran the other day down the river and seemed to run out okay. It did seem a little slow coming out of the hole to me. The boat has a 6" jack plate and is 17.75 ft long. It ought to run pretty good, Im just now sure about the prop. Im afraid its an OLD design and could really benefit from a new prop. The motor also came with a laser 2 26 pitch which I thought was waay to big for the motor. Im no expert though so who knows. Its dinged up anyways and Ill probably just unload it as a rebuilder for cheap. Any help on the ProTester would be great. I can upload a picture, but it just looks like the laser 2 without the inscription.

    thanks
    Matt

    ProTestor props were made in the late '80s early '90s and are no longer in business. You need to prop that XR2 to run 6000 rpms, so a 23" Tempest+ should do the job.

    Do you know if it was a decent prop or not? I guess what I'm asking is if I were to try to get a bill out of it would I be asking too much? I'm not trying to start a for sale ad or anything, it's just I have zero info on what to try to get for it as I have only seen one for sale in the past year on "auction sites. I appreciate the recommendation on the tempest. I was actually looking for a laser
    2 in a 23 pitch. (Seems those are pretty cheap used). I will see what I can come up with. Thanks again

    The last Protester I had was a 3-blade 24P on a '85 Ranger 373V With a XR2 150. It really ran good and pushed that old Ranger right up to 60 mph. I ran it for a decade and I sold that boat a few years ago with that prop still on it. Even though it may be an old design if your boat runs good with it I wouldn't bother changing it. I think the Protesters did have a rep for loosing blades but some props today do that and I suspect if yours is still around it is probably fine. If I remember right the blades are welded on these props instead of being cast in place. If you still want to sell it I think you could easily get over $100 for it. Hope this helps.

    The protestor is a great prop for that motor had one on mine! Does your motor have a protestor sticker on the cowling?

    Nope, no sticker on the cowl. I haven't gave the prop a chance yet really. I'm sure my motor could come up some. That and it was the first time I have had this motor or boat in the water. I was trying to watch gauges, watch for leaks, and dodge a rainstorm. I just assumed from the lack of information and the probable age of it, a lot better could be had nowadays. I did stop by the local ranger dealer one day and ask their opinion on it. He looked at it and said " well you could raise your motor up if you had a decent prop. This one has no cup to it." Who knows . I appreciate the replies
