    Default How big a deal to swap out TRS and trans

    Guys,
    I'm looking at a 1979 26' day cruiser with a 454 and TRS drive. Not sure if the trans is B/W or MercTrans. Not being familiar with TRS, I took to Google and found a decent amount of info on random forums. It appears that while these configurations can be pretty bulletproof, finding parts if they break can be a chore. Some people on the Forums say to avoid the TRS like the plague! I'm not really a fan of this transmission that sits in the middle. Seems like a lot of moving parts. This particular boat I'm looking at also came in a 350/Alpha or Volvo configuration, which is what I really wanted. But other than the 454/TRS drivetrain of this current one I'm looking out, everything else is great. So here's the question... do I avoid this boat due to the TRS drive train? I've found the Konrad replacement drives, but that's WAY more than this boat is worth. So it would likely be a Bravo swap. My investigation in the Forums said that a Bravo swap would require removing the trans (which I like), but that the motor would need to be moved back 3-5 inches! How big a deal is that? Sounds complicated.

    If any of guys drop some opinions, thoughts, and knowledge on this I'd appreciate it. Thanks in advance!

    TRS drives have bigger gears and shafts than the Bravo. They were raced in the 80's as Speedmaster 2. The week link are the transmissions. Mercruiser or Borg Warners. Hole shot the boat and parts break. Maintain and care for the equipment and it will last. The cost to retro fit is more than the whole package. Parts are available if you know where to look.

    Well since you said 'holeshot' I have to ask if launching from a dead stop to pull a waterskier out of a deep start would be considered a holeshot? If it is, then that's a deal killer. I have kids and would be for sure be waterskiing a lot. Or are you saying holeshot as something else?

    Thanks.

    Pulling skiers will be ok. From a dead stop to throttles wide open as in racing. Not so good.
