Just picked up got a 330 454 w trs. How fast will it go what prop works good with it i need more power for sure any help ???

Come on guys a guess???

Pics or it didn't happen. :lolhit: I would guess around 70ish?

Hope its better than that the activators w 500 Hp r going 90 that's a v bottom

A 330hp 454 is not a powerhouse no matter what it's in.

I know its a suburban or cabincruiser mota. I built a 598 that made 680 on pump gas w a 1050 but I'm just gonna build a 500 so I don't wreck drive or tranny

I've got one. Mines and 85 with a "trs" also. With 330 hp it'll probably run about 60 to 65. The only issue with the trs on these boats is that they set them up with a very deep prop shaft depth which is why I built a custom lower for mine raise the prop shaft up to right at 4 inches below the boat. I've got 670 hp in mine and I've been 96 in it so far with two people and 70 gallons of fuel. Still haven't aired it out completely yet.

Yeah the drive is real deep what prop u using? How did u modify lower thanks

I'm running a 4 blade 30 to 31 pitch bravo props right now. If you go to the "drives and lower units" forum you will find my thread on trs up with bravo lower

I checked it out page 7 nice job how did u locate the drive shafts ???

Thanks. There is a centering/sealing ring that I machined to line them up perfectly

How much would charge to make another lower like yours???

I had a 89 23 Daytona and at 4000 ft and 502 carburetor ran 60. built a 502 with M3 Procharger it ran 90 at 5500 ft. 8 lbs boost. never ran it at the 4000 ft.

If I were to do another idea use a imco shorty and adapt it. It's just not economical to shorten a bravo. I did it because I had the pieces and the tooling.
