Trophy plus or tempest plus
Currently running a 4 blade turbo 24p on my '88 skeeter starfire with a 175 black max on the back. Would like to replace with a trophy or tempest. Dont know if i would stay the same pitch either, most likely would though or close to. Any suggestions? Thanks in advance.

What is your goal in changing props?
-
Put the tempest on it you need all the bow lift you can get.
-
More lift and a little more speed. The one I have currently is a little dinged up and don't know much about turbo props.
-
Will I lose much handling goin to a 3 blade? And if I were to get a tempest, what pitch is suggested?
-
How many rpm's and what your WOT speed now?
-
-
New prop should put you closer to mid 60's.
-
So I think I decided on a trophy plus. Don't know if I should go 23 or 24p. Any suggestions?

I empowered my 518 dvs with a 175 pro xs. I had a 4 blade 21p and was at 58mph@5500 RPMs. I tried a Tempest 23p and I'm at 62.9mph@5790 RPMs now and I still adjusting JP. I am still getting out of hole very fast. Stability is still good as Long as I don't trim too high. I would say the 4 blade is more stable though. Depends what you want. Top speed or better handling at WOT.

I had a 1987 skeeter star fire back in the day with a 175 on it . Back then a star fire with a 150 got a mercury 3 blade 23 turbo ,175 Ran 24 or 25 turbo . I personally ran a 26 chopper but my motor was modified out . Those old 2.5 Lt eng didn’t have much low end unless you removed the exhaust can and ported the eng , but once you got them up and running they ran strong . A 24 trophy would be good or a 25 tempest where I would start . The prop your running is not know for top end performance. A trophy will out pace it no problem all the way around . If you have a jack plate set it at 2 3/4” below pad to the center of the prop shaft make sure boat hull is level anD prop shaft is level when setting eng height . You can’t go to high with those older motors as they had the 8 vertical inlet holes on the side of the lower unit . Any higher then 2 3/4 “ you will be sucking air in the upper holes we alway plugged the top 4 holes on both sides with Allen set screws and red lock tight .

I would like to try a 25 tempest but just worried about how much stability I may lose.

How do I determine my hub size (or don't' know what I should be looking for, maybe size of gearcase)? My engine is a mercury serial # OC213004. I would hate to purchase the wrong prop.

I ended up buying a 24 trophy. Got a demo model still in the original box never opened or used, just has the word 'demo' stamped on it. Got it for 565.00 with the hub kit included, not a bad deal. Thanks to everyone for their input, much appreciated.

is it a trophy plus . You may need some plugs . I would start with it holes open first . And plug one hole at a time to minimize blow out on hole shot break over .

Yes it is a trophy plus. So start out with all holes open first. Then just plug one at a time if needed?
