High five for 20' Stoker

[billbro45]

I've done some research here on the possibility of getting a high five prop for skiing and carrying a load. I have a '86 Stoker SST w/ 1997 Mercury 225 Pro Max w/ a sportmaster lower unit that spins a 26" Lightening ET @6600rpm in the low to mid 80's. I've got 10" of setback with the props haft just below the pad. Skiing w/ the ET is not usually a problem, the holeshot is OK. The problem is with small kids or heavier skiers. I briefly tried my brothers 24" High Five and I liked the holeshot but, it seemed to have a lot of slip before hooking up. Now I'm not sure on the dimensions of either his prop or my gearcase and I wasn't able to play around with the vent plugs. But if my gearcase is 4.5" and his prop a small hub, would a large hub prop get more bite? I've heard that the odd # pitch props are large hub, so do you think a 25" prop would be a good choice? Please let me know what you think.
thanks, Bill.

ya never know till ya try it...if you can get your hands on a shooter that prop works well for sure as an all around load carrier/skier kinda prop

how dose it handle with all that set back at speed?

2.5 stoker-
Thanks for the reply. As far as the setback goes it handles great. I built my own setback plate with 4", 6", and 10" side plates so I could play around with different amounts of setback, mainly to balance the boat when I changed from the 235 Rude to the Pro Max. I do get a little bit of porpoising at top speed but you can easily trim it out. Al told me not to go with that much setback but, I seems to work OK for me. Since my boat is stored at the river and not in my garage would you know if that Sportmaster is a 4.5" gearcase?

For skiing and pulling kids etc. bet a 23 would be the ticket.

I run a 21" high five on my Baker RST for skiing. All the vent holes are plugged and it has great take-off power. Pulled 2 wakeboarders out of the hole last week. I think the motor has about 12" of set-back (measured from the back of the pad).

'86 was a good year!!

I have a Checkmate 2100BR with 12" of set back and a Sportmaster gear case. I tried a High 5 for skiing and, while it pulled good, it had way too much slip at wakeboard speeds. I now use a mod’ed Bravo I with PVS holes. It is by far the best heavy load, ski/tubing/wake board prop for my setup.

Thanks Lance, I'll check them out.

I also ran a 24 small hub on a 18.5 Stoker type hull with OMC power. I also found that it slipped badley.
I found that merc made a exhaust ring that goes over the hub and stops the exhaust gases from making the prop slip.
It worked for me not sure about your lower,but it only cost around $30.00 nzdollars ($15us?) so could be worth looking into.
It was a stock Merc part for small hub Trophy props I think.
