Anyone try hydro P5xs on a 388
 

Anyone ever try hydromotive P5x,s on a 388?

Tom,I have only used Bi 4 blades and Max 5 blades. Max's were great in the mid range, but I didn't like the stress on the prop shaft....

New style thick blade B1 merc's work good
tried P5X no go
p5's ok not the best
5 blade herrings the best

So you like the 5 blade hearings the best on a 388? What power and what was you top speed ?

I have 1 in imco lower,s and my prop slip is at 20%. I'm running a custom bravo 4 blade .

real deal
 

750 dyno hp (no accessories no marine headers)
5250 rpm 1.5:1 XR
stellings boxes at neutral position
32P 5b herrings
Empty (1/8 fuel)101-102 GPS October 30th cold water, driver only (basically how Fountain tests their boats back in their heydays')
7 onboard 3/4 fuel august water 97-98GPS every day any day

herrings have to be the short flared hub (for exhaust through prop)
not the long straight hub of late design.

That's in a 388. Nice . Thank you for your info.

my next set of props will be lab maximus 28s

Ive been running the same merc stock 30 4blade b1 for 9 years now, they usually turn 57-5800 in the heat full load 98-101 and 6000 in cool, thimnk prop slip was around 20% also.

BMax 1.30 gear

Bought a set of Herring 28 5 blades, stock, it would only turn 5500, sent them into b blades cut the diffuser off and loosen up, then wouldn't get on plane ,put diffuser back on and tighten prop back up, still not getting the rpm, gota watch getting on plane will blow out,especially with a load,one blow before the other.but the look cool:rolleyes:

Ran it at Tickfaw full fuel,full water,8 people,4 icechest, 5500 was 93, so its way off.

The 5 blade seems to setting the boat down above 95,

boat dry is 8790. full running is 9540.
Herrings
2500-33
3000-46
3500-61.6
4000--68.9

How ya been
Its been a while, I don't come on here much these days.
I see the slings still working great.
I thought maybe you sold it as there was one very similar for sale in Chicago area.
Heard Mitch took great care of you, you should see the 377 after he gave it a once over... what an awesome guy.

I tried a set of maximus way to much prop (diameter) and it might as well be a #6 cleaver it weighs a ton.
Spool up suffered big time.
thanks for the insight on the B-max drives they have been flawless since Ron Bender fixed all of Dean's BS


With the B-max drives
its slow now
stock 30' B1 5200RPM 92-93gps (4) onboard with coolers & lite fuel
I'm fine with that, turn the key and drive.
Take care

PS if you want to sell those herrings let me know I'm looking for exactly that pitch and style
they were the best Wheel I ever had but with the 1:30 B-max I couldn't spin them.

double post for some reason?
delete please.
