I just completed this project with the help of my sailing buddy Les.
My Perkins engine was designed for a tractor.

The installation on my boat meant that changing the oil filter puts about a quart of old oil in the bilge. This is the engine. We are installing it after the rebuild. It slides back through the hole in the bulkhead. Once you begin to unscrew the nut beneath the filter can, oil in the filter housing leaks out all over the transmission and below. Even using plastic bags and rags, it was a mess.
Using a:
Billet 4Port Side Entry Remote Oil Filter Mount 3/4In-16 - ALY-153BK from Amazon, AN10 fittings on new hoses connected from the engine block and oil cooler. We located the mount outside the compartment, utilizing a clean spin-on/off oil filter. Changing the filter is now a simple, easy project.
