dabear Posted July 26, 2020 Report Share Posted July 26, 2020 14 1/2 X 23 Yamaha pro series PN 66K -45974-B0-00 . When I had the 150 on my HPX I ran two props a 23 and a 25 Yamaha pro series 66k-45972-B0-00 to get a couple more mph sacrificing a little hole shot . The 23 worked well stock and was on it 70% of the time . 1 Quote Link to comment Share on other sites More sharing options...
jason p Posted July 26, 2020 Report Share Posted July 26, 2020 I ran a PowerTech PTR418 on my HPX with a “regular” TLR F115. Hole shot was great and you could trim it up as high as you want. I’d run out of water pressure before it lost any grip. 1 Quote Link to comment Share on other sites More sharing options...
Ironhorsecowboy69 Posted July 26, 2020 Author Report Share Posted July 26, 2020 I bought my boat from a auction , someone had stolen the prop and 700.00 edson steering wheel, or I would have some idea where to start. I was told a Power tech 4 blade 151/4 with 17 pitch - but I wanted a little more info being you don't see this combo as often as with a 115 hp Quote Link to comment Share on other sites More sharing options...
jason p Posted July 26, 2020 Report Share Posted July 26, 2020 Not sure what a “151/4” is, I’m not really into prop experimenting, testing, etc... When people start talking about stern lift, blade cupping and all that prop stuff I check out. I just called Marcus at PT and asked what to run and went with it. There’s dudes on here that are really into dialing props in and have tried every prop under the sun that will have more info than me.

Ironhorsecowboy69 Posted July 27, 2020 Author Report Share Posted July 27, 2020 15.25 diameter and 17 pitch , I heard he is the best when it comes to props, I believe he goes by another name on here ! I can get more horsepower and do a lot of other things on a boat but when it comes to props I'm lost. Quote Link to comment Share on other sites More sharing options...
jason p Posted July 27, 2020 Report Share Posted July 27, 2020 FunkyMonkey on here... if you want a PowerTech prop I’d just give them a call and they’ll give you their recommendations. Mercury Spitfire props work really well on HPXs w/115s as well, XR7 21 pitch if I remember correctly but don’t quote me on that. Quote Link to comment Share on other sites More sharing options...

Mercury Spitfire props work really well on HPXs w/115s as well, XR7 21 pitch if I remember correctly but don’t quote me on that. I thought that Ironhorsecowboy6 has a HPX with a 150 HP sho on it that’s why I told him what props I used on my HPX when I had the 150 on it . I bought and ran a bunch of props on my 150/HPX to find what worked best for me before running the 14 1/2x 23 and 14 1/2X 25 pitch Yamaha pro series . I agree with your Spitefire suggestions if you have a 18 HPX / 115 sho .it does run well on my boat with that combo ,I also like the PTR pro3 13 1/2x 21 on my 18 HPX/115 sho combo as well as the Yamaha K 13 1/2x 21 pro series . 1 Quote Link to comment Share on other sites More sharing options...
jason p Posted July 27, 2020 Report Share Posted July 27, 2020 He stated “looking for load carrying and hole shot ”, shouldn’t he be looking at four bladed props? Quote Link to comment Share on other sites More sharing options...
dabear Posted July 27, 2020 Report Share Posted July 27, 2020 I have had both three and four blade props with incredible hole shots when your not spinning to much prop for your motor to reach its maximum RPM and it vented if needed I have had good luck with hole shots with either . The 150 on my 18 HPX V was not as prop sensitive to carry extra weight or hole shot as my 18 HPX is with the 115 SHO . Lots of things effect the hole shot prop diameter, motor height, boat balance / weight distribution , barrel length a short barrel with a flare end usually has a better hole shot than a non flare longer tube prop . ventilation hole size , how the pitch progresses, the shoe string size of the blade , a sharp v leading edge and a 90 degree sharp square trailing edge , balance , how exact each blade is to each other . All of the above effect hole shot . I wish it was as simple as a 4 blade or a three blade . One of the few props that I have never owned or tested but sounds like a great prop for a HPX I think would be the Power Tech Pro 4 . A design very close to the Yamaha K Pro Series in a four blade just sounds like something that should perform great . On some hulls the pro series doesn’t grip well in turns but is fantastic running straight that 4th blade may be a great addition on that design . May be worth asking Marcus the funky monkey about .

jason p Posted July 27, 2020 Report Share Posted July 27, 2020 Gotcha, I really have no idea. You lost me at barrel length🙂 You did remind me though I forgot to mention to the OP that my PTR4s had 3/8” ports as recommended by one of Marcus’ guys at PT.

dabear Posted July 28, 2020 Report Share Posted July 28, 2020 Ironhorsecowboy69, did you get a prop yet for your HPX / 150HP set up yet . You should try a see if anyone in your area has a 14 1/2 X23 Pro Series Yamaha prop or a Power Tech RKR3 in a 23 . I don’t think a 17 pitch prop will work very well on a HPX with a 150 SHO hanging on the rear if Marcus at Power Tech told you to get a 17 pitch maybe he didn’t think you have a 150 HP SHO on it .

Bigfish123 Posted July 29, 2020 Report Share Posted July 29, 2020 Do you have a fuel water seperator on your boat? Trying to figure out where to install one for my 18 Hpx. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
dabear Posted July 29, 2020 Report Share Posted July 29, 2020 Mounted on the inside of the transom under the rear center access hatch . Are you sure the factory did not install one there ? Joe R Quote Link to comment Share on other sites More sharing options...

dabear Posted July 30, 2020 Report Share Posted July 30, 2020 Geeviam , you are so right about the expensive part . It’s so easy to talk about props than start doing the wonder how a Pro 4 would work thing , the wonder how prop game is very time consuming and very expensive , than there is the added cost when you buy a prop that gives you the best performance of ant stock out of the box prop and you send it out to be fine tuned to do a little more of what you want $$$ , Ive been thinking that the Pro 4 should do pretty much everything the Pro 3 does but may have more over all lift , may have a little better hole shot , may have a little more grip in a sharp turn situation. I heard that they have been used on some Carolina skiffs with Suzuki’s with great results . I have not heard of anyone testing a Pro 3 and than a Pro 4 on the same set up and compared the two . I also am not sure how much RPM drop there would be between the two . I am guessing to drop from a 21 to a 19 to maintain the same RPM but that just a guess . I really shouldn’t talk about props because it’s is so easy to think what if . $$$ . Joe R 1 Quote Link to comment Share on other sites More sharing options...

The OFX 4 in a 19 should have a amazing hole shot . You would leave a little top end on the table but if it’s a hole shot you want that should have a great hole shot .

Thank you Marcus with Powertech for the advance and help. That should be in the ball park . Don’t get in a hurry fine tuning the prop and balancing the boat until you have a few hours driving it under different conditions with different loads . Figure out how you will use your boat most of the time , the amount of gas you run how many people are usually in the boat where they sit running shallow running in rough conditions . When you figure out what you do most of the time and what’s more important(speed ,hole shot ,lift , ride, running shallow, all of the above ) than you can fine tune your set up to meet your needs . Not to many company’s have someone like Marcus giving free advice and trying to hook up his customers with a prop that will give them what they are asking for . We all drive , set up , and load our boats differently and there is no one size fits all prop that will but a smile of everyone’s face . A prop one guy loves the guy standing next to him may not be crazy about . Good luck hope you get many years of fun out of your HPX . I love mine .
