TRS coupler # 57758A2
 

has anyone a.m.TRS coupler new or with low running hours for sale

If its the coupler that connects to the transmission, i have two used ones with about 260ish hours on them. Had to buy different ones for my new drives so planned on selling these along with a bunch of other parts once i got around to it.

the input of the coupler is connected to the Borg Warner 72C gearbox output shaft with 24 splines and diameter 1 9/16 inch,
the output of the coupler is connected to the TRS input shaft with 17 splines and diameter 1 1/8 inch (see attachment).

It sits inside the Mercruiser tailstock # 98322A2

ok yeah i have two of them from my trs's. When i switched to the Konrads i bought their tailhousing assemblies for replacement.

could you please post a photo, are you selling the coupler with or without tailstock.
What other parts are for sale, and how much are you asking
