does anyone know what this is? LOOK!
 

this is a drive i picked up today. it looks to be a trs but the lower isnt. is it a speedmaster? any help would be great.http://i891.photobucket.com/albums/a...0/DSC04473.jpg

Looks like a Merc 215E or 215H from the mid 70s

its a strange critter, the upper shifts into fwd. or rev.---no neutral, the long tail shaft plugs into a clutch disc/like car set-up which provides the neutral. All shifted by a electric shift/servo box all at once, the clutch disc and the drive rotation.

ok i just looked close at a trs upper unit i have in the garage. this unit i found today has a pin i comming out of the upper on the other side of the oil pick up. thats the shifter pin?

Any serial numbers on it. ???

Thats what it is. No doubt about it.

no numbers i can find under all the paint and dirt. looks to be a 215e like said. it has a shift pin just under the yoke.

Merc was in bed w/Ford at the time, that drive was mated to 302 and 351-----it let to the design of the MercTrans next,which has Ford parts in it.

Yep, that's the 215E. It was made from 1970-72 ' using serial numbers 2909035 thru 2915034. As stated earlier it was a crazy set up with a automotive type clutch for nutral and forward-reverse shifting in the top end of the drive. Easily identified by it's long drive/yoke shaft and shift coupler between the drive and transom bell housing.

The 215H was more like the TRS. It used a hydraulic transmission (probably B-W) with a tailstock like on the Borg-Warner which bolts to the transom plate. There fore it had a short drive/yoke shaft.

1973 the TRS was born using the Borg Warner and then the Merc Trans ll which shared some internal parts from the Ford FMX transmission.

have you ever seen an early trs with the same type of long input/yoke shaft? i think i have seen one.
