With a mechanical system tq'd up at 400ftlbs...and getting it shocked like prop impact, can really test the parts, no doubt.

Weak link on the output shaft...check. I suspect if that didn't get hurt on a hard prop impact, then something next in line possibly would.

Key here I suppose...is don't hit stuff!

Pacific Northwest area has a lot of deadheads though. So always a risk no matter the precautions taken.

So True, Kirk was a old school type of guy... He shared his knowledge to me and others for many years, RIP.

I am looking for a oil cooler for the side of a merctrans 11 ,I see afew in the picture ,are there new ones available or will you sell one ?
thanks Brian

The oil cooler is a simple metallic tube that is mounted and sealed through a cover plate.

My intent, is to have more active ATF cooling method. This would also give a larger volume of fluid, for a greater thermal mass.

Hello all,
I just joined this site today in hopes of getting some help from anyone out there that could help me piece together all the seals and orings required to seal up a merctrans. I picked up a merctrans a few years ago and would like to go through it but the orings seem to be the hardest thing to figure out. Also I have a merctrans case for a Ford engine if anyone is interested, i am only using it at the moment to try and source the orings and seals needed. My boat uses a Chevy, Once I get that figured out anyone out there that needs it can have it.
Thanks to everyone out there.

Figure I'll throw this out there for anyone searching
merctrans rear output seal TIMKEN 450593 or CR 10050
