The 28' Saber is a great boat.
I am curious as to what outdrive it has on it.
1987 was an interesting year for Mercruiser outdrive availability.
I found a 1987 28' Scarab, a few years back, that had a Bravo outdrive. Had to be one of the first Bravos as they were more or less introduced in 1988.
The 454 Magnum came with an Alpha in 1987.
The TRS was still being used in 1987.
Do a search on this site for more information on the 28' Saber.
