Wanaflatsfish Posted March 27, 2022 Report Share Posted March 27, 2022 i am just getting to play with the beast And realized the bravo is ported the previous owner had the ports closed so I popped out the inserts any comments from other hps owner’s I remember on my 22 pathfinder f150 power tech it really spooled up the hole shot Quote Link to comment Share on other sites More sharing options...
smilemaker Posted March 27, 2022 Report Share Posted March 27, 2022 My understanding is that you can use different sizes inserts to fine tune the amount it revs up. Have never seen any data with different size holes. Quote Link to comment Share on other sites More sharing options...
jh141 Posted March 27, 2022 Report Share Posted March 27, 2022 I have the SHO and a Bravo 1 FS. My best results were "with" solid plugs. Please Let us know what your results are. Quote Link to comment Share on other sites More sharing options...
Bamaskeet Posted March 28, 2022 Report Share Posted March 28, 2022 My understanding is if you get at least 3500 rpm immediately when you pour on the coal, you don’t need porting. Quote Link to comment Share on other sites More sharing options...

Got a chance to run the HPS today..... spooled up in FLL Inlet....woooozer Sounded like a "jet engine"....and the hole shot was instant.... Had the wife and daughter in the HPS and we ran off shore for about 15-20 minutes.....nice ocean chop and it ran great.....near and mid-range acceleration is instant.... I goes from 0-3500 RPM's in about 2 seconds and up on plane....250 SHO with T top. dc Quote Link to comment Share on other sites More sharing options...
HoneyB Posted April 4, 2022 Report Share Posted April 4, 2022 I would have said that you didn’t need to open the ports on the SHO, but since you had good results I guess the point is mute. I would say that you could likely buy the plugs with smaller holes and get good results rather than having them completely open. I have a different hull but I run my Bravo with solid plugs it seems to spool up really well. 1 Quote Link to comment Share on other sites More sharing options...

I have not yet checked the prop in shallow water so that will be another day...for me, spooling up and hole shot will be most important when fishing Everglades park. let's see after the first trip. dc Quote Link to comment Share on other sites More sharing options...
BradM Posted April 15, 2022 Report Share Posted April 15, 2022 Hey DC, Hole shot will be insane with the open plugs, as they allow exhaust gas to escape around the blades to help spool up the prop from idle or low speed. The design intent is to address the lack of low speed torque that 2 strokes produce; it helps them take off until they get plane and get into the meat of their powerband and turn bigger props efficiently. The 4 stroke SHO has gobs of torque down low, and will have no problem spooling up that (is it a 23p?) prop. With the introduction of exhaust gas AND the low end grunt of the SHO, you risk true cavitation during the life of the prop, which will inherently be short. Keep a close eye on the condition of your prop if you decide to run it with open ports. To me, the trade off isn't worth it. A 22p will rocket out of the hole and run close to 60 or more with the t-top. That 23p was cast from a 22p anyhow, so it's close, it just has some cup that was added by hand and eyeball. Oh, and you can buy the plugs off eBay, too. Good luck! Quote Link to comment Share on other sites More sharing options...

Took it the Everglades last weekend with the family and my grandson to catch some fresh water goodies.....6 people in the boat...hole shot 1.5 boat lengths...yes, it grabs....and rocks forward....I had the OFX prop on my Pathy 22 and a F150..it was a 17 ported and it jumped out of the hole.

Wanaflatsfish Posted April 17, 2022 Author Report Share Posted April 17, 2022 see my post in 10k's for more info...but, she ran pretty well.... and 54.9 is WAY WAY TOO FAST IN 3 FEETOF WATER dc 1 Quote Link to comment Share on other sites More sharing options...

More Sunday... dc 2006 Pathfinder 2200v with 150 4s, Bob's Machine jack plate, and OFX4 17 pitch. I am thinking about getting the prop ported to help increase hole shot. Any thoughts on ported vs non-ported on that set up? Quote Link to comment Share on other sites More sharing options...
HoneyB Posted May 13 Report Share Posted May 13 I do not have experience with that set up but for what it’s worth even a four stroke 150 should be able to spool a 17 pitch pretty easy to get out of the hole. I would be surprised if there were much gains drilling the current prop. Quote Link to comment Share on other sites More sharing options...
MaxTheGreat Posted May 13 Report Share Posted May 13 It does jump on plane very well, especially compared to the stock 3 blade prop. I'm curious if there are any downsides to porting, and if it would help even more like during shallow water starts or pulling a skier.

jh141 Posted May 14 Report Share Posted May 14 I have never had or heard of porting helping a four stroke. It was a Great tuning tool on the two strokes due to their lack of torque. The high pressure injected two strokes also are less effected by porting the prop I Tested my 4.2L SHO with my FS1 Bravo prop all open and solid plugs. There was no real noticeable difference and I run it with solid plugs. Very early on when my SHO was new and I was running a P.T. OFX 4 it came with 3/8 port holes. I sent it to Frank and Jimmy's and they welded them up and balanced it for me. ( I hated that Prop ) My Yamaha HS4 21 run 100 percent better than that OFX in every way. HS4's do not have ports.
