I want to GO. Which prop will make it go?
I'm into rebuilding/upgrading some carb stuff on my 2001 GP12r; and the next thing in my mind is an aftermarket prop.. I want to hit low 70mph range at about 7100~7400 RPM. What can I plan on getting for prop, ride plates (angles) and such to get me there or more? I've got interest in holeshot, but more interest in top-end. Being lake-driven, top end is more important to me than navigating unsettling waters, though I still love to safely jump boat wakes. I might take the Ski to Tampa once or twice. I'm thinking of getting the tried and testing Solas Concord 13/19, but a 13/20 or something else might work too; thus I trust and ask the experts here.
Here is what I'm putting in this weekend:
- Rebuilt fresh kits with all new replcaable parts
- 110/125 jets
- 95g spring
- Chokes removed
- Restrictor mod
- Pre-mixing 40:1
- PROK Flame arrestors
- WPS adapter plates
- Probably some modification to the intake hoses once I understand how rich/lean tuning is
- Riva Intake Grate
- Riva Pump Seal Kit
So thats what I've got so far. If this plus a prop will get me to 70mph then I'll be stoked, otherwise I've no problem looking in to more stuff such as the following:
- Upgraded head (150psi)
- Reed stuffers
- Free flow exhaust
- Leo Holeshot
Does everyting look good? I dont think I am - but if theres anything blaitantly obvious that I'm missing please let me know

I have a good Solas 13/19 if you need one. Ran it on my ski before I put the big bore in it and it work very well for my setup. Its got about 2 hours on it. I think you and I conversed on some of these parts once but I dont think I ever got back to you on it.
Also got my 155 psi head modded by Riva available. Actually have 2 of these I am taking the one off my 1512 motor and putting on a 175psi head. This one was done by Lowell Horning I believe as the motor was built by WATERWOODY at WestCoast Porting
Here was my setup
1200 PV stock bore no porting
Stock Exhaust with D Plate
Riva Stinger 2 (hated it)
Pump Shoe Seal Kit
It ran 72 on good water and weather

I would look for a used set of oem 1300 reeds (a little better than the 1200's and more durable)
For prop you should try a stock 1300, 2005+ large-hub prop.
-I know this makes NO SENSE cause the prop hub over-hangs the stator by 5mm all around but it's worth a try.
I dont suggest this only because those props can be found for $0 but I have had good results with this combo with no cavitation issue.
