The TRS drive is stronger than the B1's, but yes, they also have their limit, they are heavy, take hp to spin ect. 500+hp is pushing it with a TRS, but a sure time bomb with a Bravo, even if they come with the 525EFI and 600SCI. Now a days it gets worse with the Bravo gears being junk. Bravo drives suck, in any shape or form.

Got 565hp a side in mine hooked up to TRS's and no problems. Love the way the tranny's shifts so smooth!! If I ever have to switch it will be to a Konrad!!

I have had 600HP per side for the last 3 years in front of my TRS with no problems. I had a friend with 700HP+ on a 86 Top Gun and would go through 1 sometimes 2 drive a year.

Only time I had a problem with my TRS is when I blew an upper cause I only put 1.5qts of oil during my first drive oil change. I know it takes 3qts now.

No I bought it here Lake of the Ozarks

Ok cool. There was a '79 300 with 454/TRS near Chicago with porno red interior for sale for a long time that had been full of water.

I would not waste the time to change from a trs to a bravo. It would require a ton of work, for a drive not as strong. My friend ran 700hp 540s in a 79 scarab 300 with trs. 90mph boat and no drive problems. He also ran it like he stole it and in rough water.

It sounds like your talking to a lot of guys who are giving you bad info about trs drives. As for trannies going bad, and having to pull the engine, etc...true. But what about blowing a bravo coupler?? Having a merc trans or velvet drive rebuilt isn't much more than a coupler job. Plus the trannies shift soo much smoother.

The limiting factor might be the Merc trans on some setups. I know the stock Merc trans will take less HP than the TRS. The BW velvets can take more power. When I had my BW's upgraded I had the 7 Kevlar plates installed and now should be good to 750HP.

True, I had my BW 71C's built to Huber 925 specs when I owned the boat. It wasn't that much to upgrade the trannies.

I got friends that ran up to 700hp with trs drives, b1 is450hp drive, but I put 585hp/600/650 hp on a single b1 on my 24ol for 12 years or so.if you have trs and hp above 600hp going with a konrad is the way to go. there rated at 800hp, my motor is more than that on the saber.konrad is shorter than a trs better bulit so its faster.

Wait until it blows up and then switch to bravo..
