Is this a TRS?

I have an outdrive that i believe is a trs. The serial # is 4521589. It is currently on a 27' century behind a 454 330. Whats the difference between trs 280 & 330? Any help is appreciated.

Could also be a TR on that style boat. How big a prop can it swing? TRS is 16" max, TR is 20".

Same upper unit, differant lower.

The serial # listed is to old for a history, but it falls into the TR range in the EPC (Electronic Parts Catalog)

Does the bullet area where prop shaft and carrier are look to be the same diameter as a Bravo or Alpha than a TRS if its bigger a TR. TR has also has bigger prop shaft.
