Bought an 89T/G last year and ran it some this summer getting used to it. 502's (Don't know HP) CMI Exhaust and TRS Drives. I am turning 23 Mirage Plus props at 52-5300. Everybody telling me to go to 4 blade wheels but I have been hearing disturbing things about use on TRS drives? My drives are like new and I have 2 Almost new spares. If I were to build 2 new engines to 650-700HP keep my TRS Drives,What propeller would I then use???

I like a Mirage Plus on Top Guns with TRS's. You acan run a Hydromotive Quad 4 as well. Just have to be on your game when she leaves and re-enters the water. The lower gears are what usually goes. If you are 650-700HP at the flywheel with new power you are right at the max for a TRS.

Post some pics of your ride.

I have 26p bravo props with my hawk 525s & trs.

I know a few guys with trs top guns, I've run with both mirage plus and bravo1 props. Mirage plus run very well with a little more room for error over the 4 blades. But I think at the 650-700hp level your going to need 28 bravo1's and nose cones. Slip goes up a lot above 78 without them.

I am not sure I would run the 4 blade unless you need them, I just repowered my Mistress, 600 a side, I am gonna try 24 Bravo1's to see what it does, but expect to be at 25 Mirage plus @5200 where my engines make power..

Right on the money! Agreed 100%

Wonder how I learned all that???? lol

When I had my Top Gun with TRS (700's) I could not get any life out of the TRS when runing 4 blades. The right hand lower pinion gear would spit the teeth out at the root. 3 blades got a little more life but still went through 6 drives during the 2003 season.

No wonder you became a test subject for Konrad! You are hard on some drives! Haha

TRS need to go with any hp over 550 to 600 .
