The TRS was the pre Bravo drive. It was a good drive in it's time. It was the performance version of their "model I" drive. (in their time)
Unfortunately for you, it isn't worth much on the market. If you can find someone who needs an older replacement drive, then and only then will you know what it's worth.
If you decide to renovate an older boat, you have to decide these things....
First, your budget
Second, if you really like the boat and if it suits your needs Third, after you establish your budget, weigh that against resale value. When you get bored of the boat and want to sell it, see if you will get back the money you put into it.
Fourth, If you decide to renovate this boat for enjoyment, then skip everything above except for the budget part.
Lastly, check the current market value for older Sportcraft boats. That will probably steer you in the right direction.
