I have a new Fury 24P, 14″ prop to try on my 08 Classic. I have not run it yet, as the weather has been too cold and windy for me. The prop came with out any inserts, so right now it has 3 open holes. I can get the inserts and I am debating getting a full set or waiting till I try it as is and then select some inserts to try. I am running a Yamaha 175 HPDI and took off a Yamaha 25P, 14.5 dia prop that came with my boat. What is the best procedure to test the prop? Launch the boat and leave the trailer in the water, take it out for a spin and then come back, load up and adjust the inserts and repeat the drill or try the prop on a fishing trip and then make the judgement. I am thinking with 3 open holes that I would get quite a bit of slippage, but I might be wrong. I was considering getting 3 solid plugs and working down from there by removing one at a time. Or, changing 3 solids for 3 large hole plugs, then if necessary, 3 medium plugs and etc. Which is the best approach? I did not have a complaint about the Yamaha 25P except for a boat lean to the left on my hole shot. I was running 64+ with a full fishing load and pardner, live well empty. After further consultation and posting, my new prop may not have that much effect on the lean to the left, but I want to keep the prop with the best all round performance, lean or no lean. I have found one difference in Mercury and Yamaha prop installations. I sure like the crimp over nut cover from Mercury better than installing and removing the cotter pin on the Yamahas. I have changed props before on my old Merc., and it took just a few minutes. I spent a lot of time getting the cotter pin out and getting the nut centered on the hole, and tight enough to insert the pin, having to hammer tap the pin it in and out, because it was so tight. Suggestions appreciated. Skipjack
My guess is you will be surprised. I know it is a bigger motor and prop but I am not running plugs in mine at all. Just running it the way she came out of the box. You can do it anyway you feel comfortable. If the ramp isnt busy then I would leave the trailer in the water and go out and see how it comes out of the hole. If it is fine then park the truck and go fishing. Good luck and I think that prop will surprise you…impressive to say the least. Let us know how she does, I dont know anyone running it on a Yamaha.

Im running mine on my 250 ProXS without any plugs, but that going to vary from boat to boat and engine to engine. Everyone Ive talked to has been inpressed with the Fury, so Im sure you will be as well. Let us know how it works out, Ive got a friend who wants to try mine on his Yama when we get a chance.
Pretty day in low 70s so I ran to the ramp and my wife backed in the trailer so I could try the 24P/14″ Fury on my Yamaha 175 HPDI and Classic. River was at high tide and smooth. First I tried the hole shot and it was as good as the Yamaha 25P if not better. I have not timed either, but it is plenty fast for me. Not much difference in throttle down or easy down. Gets up fine for me. As I suspected from consults, I still have the lean to the left condition and if that is way its going to be, no big deal. On my first run, I had my jack just about neutral and got it up to 63, taking it a little easy to get use to the thrill. I adjusted the hyd. jack down a tad and tried it again and I was at 65+ but only turning about 5400. I then made a few runs in both directions and got it to 66 GPS at 5400 RPM. My motor according to the specs should turn up to 6200, the only difference in it and the 150 HPDI that turns less. I suspect if I got a little brave and trimmed up a little more or raised the jack a tad, I might get it to turn up more and add a little to the speed. I just did not want to try to overcome a sudden chime walk with my left hand on the wheel and my right hand on the throttle. At 66 MPH I had no chime walk. My Sabre would start to chime walk at 63 MPH. Everything was the same today, except I was by my self and that could make a difference. I have ran the boat at a little over 64 with the Yamaha 25P and with my fishing pardner. (with the wind that day, on a chop) MY question now concerns efficiency. If I put in solid plugs, what would that do to my speed and gas mileage? I know it could effect the hole shot, a little slower I would guess. I could reduce the holes to med and get a compromise? When it is all said an done, I dont think I will be running at top speed very often. I like to cruise at 50 most of the time or less when it is cold. I may fine someone with more nerve and more chime-walk experience to see just how many more revs this Fury has on my Classic. In the mean time, I would like to find out if the plugs would add anything or take something away. From some of the posts, the plugs can be critical to high speed performance. Skipjack
The plugs have zero bearing on top end. They are for adjusting prop slip coming out of the hole. I have a 25 Fury on my 175 ProXS, I went out and got plugs thinking I would need them but the prop just bites and yer gone. I still have the plugs inthe glove box, I guess in that aspect they slow me down by extra junk in the boat LOL.
John is right about the plugs. They are used for adjusting hole shot, but do not affect top end performance. Sounds like you have the 175 Yamaha doing pretty well with the Fury. KentKent Charles 2002 Pantera Classic & 200 Yamaha VMax
The plugs will not effect the fuel efficiency. They are only a regulator of hole shot. BCB
It looks like I am getting very close performance with either the Yamaha 25P/14.5″ prop at 5200 and the Fury 24P/14″ prop. I have two left over SS props from previous boats and I am thinking of trading for a spare/extra prop. One is a 22P LAZER and the other one is a Merc 17P that came off a 200HP on a 23 Ranger Center Console. In the interest of raising my RPM range on the Yamaha, if I drop down to a 23P 4 blade prop, could I expect to top out at higher RPMs and get similar speed and performance? My motor is rated at 6200 RPM and it seems to me that it would be better to be operating in a higher RPM range, like 56-5800 RPMs and the 4 blade would give me a better bite than a three blade in that smaller pitch. Im just thinking out loud, but I would go that route if I would be raising my RPM range and still getting speed and hole shot. Any thoughts on that? I may keep my 25P Yamaha prop as changing props did not effect the tilt to the left on the hole shot. It was suggested that if I had a lower unit failure in warranty, a different brand of prop may cause a warranty repair problem. The Fury did raise my upper range RPMs to 5400, plus 200. I am going to try it one more time before I choose the keeper. Thanks for the input! Skipjack
Going to a smaller pitch 4-blade prop would most likely help improve hole shot significantly, and with increased RPMs, you would probably maintain similar top end performance. I bet a 23 Trophy plus would break your neck coming out of the hole. Sounds like you are mostly concerned with hole shot, and a smaller pitch prop would help with that. Im not real familiar with the Fury props, but maybe even a smaller Fury would be the best all around performer. KentKent Charles 2002 Pantera Classic & 200 Yamaha VMax
Dont spin that motor over 6K…they just dont make much power over 5800-5900 and they will last a whole lot longer. 6200 is the red line but there is honestly no reason at all to run it up that high…we arent talking about a Merc X motor we are talking about a working motor not a go fast motor. That is my 2 cents and I think a Trophy would be a good choice as would maybe 1 pitch smaller Fury (if they make it, not familar if they make one in a 23 or not) but I am guessing with some seat time that Fury is going to be a few hundred more RPM than what you are running now. Good luck it sounds like you are getting her close. JL
