OSE Outrunner cooling system

Looking for photo or diagram of cooling system on outrunner mini outboard.
Thanks

This is Steve's listing for the motor, but in the photo you can see the motor mount/heatsink: https://www.offshoreelectrics.com/pr...l-F450B-KV3000 It appears to be a heavy aluminum angle (or casting, I can't see all of it) with a drilled water pathway through it.

EDIT: Here's another photo (you have to scroll through a few images on this page to get to it). https://www.offshoreelectrics.com/pr...prod=ose-80980
