Anyone ran P5x props on a gladiator
 

Tring to get some prop info on this boat. I have 6 blade herrings and want to settle down the asss of the boat. It gets loose over 100mph.

Check with Brett at BBlades, but from what I have been told, more blades make for more stern lift. or may want to check with Herring/Ben Robertson.

I did I cant decide what to run next might run staggered size 6 blade herrings or 5 blade herrings. P5x is also a candidate

I would try 5 bladed Herings

i wish i had your problem

Got a set of p5s. They were on a slingshot with 700 plus a side with a 1.5 gear ratio. They are labbed 31s. Were not on the boat very long and in perfect condition. PM if interested.

Try driving the boat a little longer and get the feel for it and you might figure out how to make the stern settle down... in the end you might save $$$ on props.

I got ya good idea. I also just wanted to see if anyone with more expierence in the Gladiator had any good ideas.

Hang on to them. Might need them next weekend.

You know where they are, give Brett a call, there is a set of 4 blade labbed mercs there too.

You might try a set of 4 blade 34 or 36 non labbed bravos, they are very stable on my gladiator at 110, they do cavitate some on hole shot but with a little throttle time you will keep it to a minium, i also run 29.5 6 blade herrings they are a great all around prop they do tend to feel loose at 110 but not unstable

I know bravos are a good prop but I dont want to fight to get the boat on plane.

4 blades won't be a fight, just not as effortless as the 6 bladed props.

36-4 blade non-labbed bravos...

My six bladed Herings get the boat on plane like a ski boat. No tabs, just go. The 4 blades are too much work where I boat .

My boat is setup with a very high x dimension. 1.5" abouve the bottom of the boat

I think that Phil dropped the X dimension slightly for 04 and up.

I have some 5 blade herrings in the works soon to be mine. I think its going to be fast i will keep everyone updated. I have put some more seat time in the boat and found that the boat like a little tab to stabilize the ass but it doesnt slow it down at all. 107.4 and then it hits a brick wall. I think the motors are running out of steam at 5700 so I am going up to 31 pitch 5 blade herring which sould be just right if my theory is correct. Let you guys know as soon as I get them on the boat 110 here i come.

Very nice! What was your power again?

Just wondeing how things are going with your props. I put 34 Maximus props on mine today. Great planing, cruise, and midrange. Got the speed back to 91. Problem is at about 84-86 the boat chinewalks bad. You have to excelerate fast through it from 80 on to avoid it, and the boat just doesn't feel as stable as the Bravos. Anyone have any ideas.

5 blade Herings!!

I tried the Maximus and went out when the lake was very rough.(25 mph winds and whitecaps). The boat crushed the water and felt great, probably due to the bow being up. The next day, a weekend day with lots of boat traffic, I took the boat out again and the boat handled the cross chop miserably. The boat felt unsafe. I could have done some more tweaking, but why bother. The 6 blade Herings are the best prop for a 525 Gladiator.

If you think the Bravos feel stable, try some 6 blade Herings. They are smoother, handle better and the boat feels like its glued to the water.

The water was very smooth today. We think that has something to do with it. I'm wondering if the diameter has anything to do with it. They are 15 5/8. And about 1/8" between blades and cavitation plate.
I would like to keep the Bravos, but I lost 7mph here. 36's would work but I think it would suck out of the hole.
Paul, in or out?

What power? Always spin in!

Spin in. By the way, Cigarette tried the Maximus and didn't like them. Hering 5 or 6 blades or 34 Bravos. Those are the only choices I believe for a 525 boat. What was your top speed in Fl and what is it now? Lost 7 mph?

92 in FL. 85-87 here with thottle left. (on limiter). That's why I changed props. I'll call Herring Monday. The boat is no fun to drive in the upper 80's.
Thanks for the help Paul!

BTW The boat was on rails on Biscaine Bay with the Bravos at 90+ in 2+ footers.

Have fun and be safe at the lake Alex. Might try the classifieds for a use set of Herrings. Have a few for me down there, going to try next weekend if everything works out.

Might try yours tomorrow to see how they act.

For what it's worth I still thought the boat was fun at 87 LOL. There is definately more there because even with the wheels today we still had 500 rpms left from the Rev in extremely cool, dry conditions. Sounds like the Herings might be the ticket.

Have run the rest of the wknd. I'm bummed I hand to come back home.

Could it be you lost some mph due to freshwater or altitude? Also, it has to be cooler where you are vs Fl, and technically, the boat should run faster in the cooler weather. Now that I think of it, when I have run at the end of the season, in cold, cool temps, I have bumped the rev limiter alot easier reducing my top end speed.

No doubt the speed loss came from the switch to fresh water and I'm at 355' here. My slip went to 27% here.

Exactly what Paul said for prop selection. With labbed 34 Bravos we ran a best of 92.9.

I am at 504 at the lake. What was the temperature?






P.S. I hope that Joe didn't use race fuel for your test ride. :D

You guys have alot of seat time in a Glad.

Damn, Should have not said anything Paul...:lolhit:

No, I ran 87 sunoco for him...With 3 adults and approximately between 3/4 to full of fuel in 2 footers 90 MPH...34 bravos..I have run 92 with 2 adults and less fuel..

I think the Herrings might do the job along with more seat time to get used to the way the motors like to run..Drive trim will also help..

When In Doubt, Trim It out!!!!!!

Alex, anything you need, give me a call..I know how to run that Boat...

:drink:

I,m thinking it was the cold temps. My boat had a a hard time hitting 90 and was bumping the rev limiters in a temp of about 55. In warmer weather, 90 is no problem and you run out of lake before you grab the last several mph,s.

We have alot of space to let it run and air out..This way you can play with the trim a bit.I think the boat runs alot better when you have some chop..In flat water it doesn't get any air under it and sticks to the water..
