I misplaced the rear bolts and nuts that mount the trans to the rear transom assm. Left shop before checking with calipers and measuring for length. Any ideas what size these are? If I had to guess I'd say 7/16 or 1/2 by 4 1/2 fine thread.
Tks

They are 5/8 not sure on length but think they are longer than 4-1/2.

This is off bam. SCREW, (.625-18 x 5.500)

Thank you. Can't believe I misplaced them.

WTF???? Never seen a MercTrans that bolted to the transom assembly. MercTrans tail stock slides into the transom assembly then you tighten the retainer on the end of it which expands the doughnut. 1/4 inch fine thread studs with locking nuts. Sounds like your talking about a Borg-Warner.

Omg your right. I've had my engines with trans mounted covered with sheets and was finishing bilge rigging and cleaning the other day I made note I needed those bolts. (Thought anyway). I've been stumbling over Borg warners in the shop all winter and with out even checking my merctrans I just assumed they had same tail stock on the trans assm.

Oops. That explains why I couldn't find my bolts huh. Wtf

Engine looks good! What's the pump mounted by the tranny?

I installed electric oil pumps/prelubers cause these engines will sit a lot btwn uses.

I also thought he was talking velvet drive.

How much power is that motor? Might want to put the velvet drive in now and save money!

That engine is looking at that merctrans like it is a tasty little morsel that it can't wait to do really bad things to...
