Anyone replace trs drives with Bravo's?
 
Has anyone filled the transom and cut out holes for Bravo's to replace the trs drives? Did they use a driveshaft where the trans use to be or make new engine mounts and move the motors back? Just wondering how the boat handled after moving the engine back roughly 12"

Yes, buddy has done it. Engines moved back closer to 18 inches, i believe prop shafts came up 2 inches. Boat goes great.

Id look into the Konrads, might save you some aggravation,

Just figured Merc parts would be available easier and I would eliminate trans and their weight

The transom alone could be over 5k unless you are doing it

If I recall, motors need to move horizontally and vertically or have the transom redone for the different drive height.

I was strictly a Bravo guy for the same reasons until I owned a TRS boat, the feeling at the helm is completely different, especially around the docks. If you’re easy on them and watch how much HP you stuff into it, you will be fine.

Definitely enjoy both types now but I am now less skeptical of the TRS package.

I just hard time finding parts for trs and I kept burning up Borg and warners

What about using jack shafts between motor and Bravo?
Would have some wasted space but would be easier to work on, maybe

Upgrade to Konrad drives. The transom assembly stays the same; you use Konrad’s bell and drive. The standard 540 is two inches shorter than the TRS and there is an option for another two inches shorter though you’ll probably hurt planing ability with that one unless you modify the stern (notched transom etc).

The TRS is a great drive. If you’re eating transmissions, you’re a) grossly overpowered (easy fix, add clutches and plates), b) water is getting into the trans (if the fluid is pink and frothy you have a leak and it’s toast), or c) you’re leaking and running out of fluid (a bad drive plate can cause havoc on the front seal of the trans).

Personally, I’d take a TRS over a Bravo any day.

And to add... Formula says the 502 Bravo 311 (1991) runs 69 mph (390 HP 592). My 311 502 MPI TRS ran 67 no matter what, 70 on better days, and a best of 72. People say the extra weight and drag are detractors of the TRS. I haven’t found that to be the case with my 311.
