Photo of the belt-driven "sea-water" pump, forward, on starboard side (fuel pump and fuel filter removed.) The dipstick is on the port side:
Drain plugs and petcocks -- port side
Above photos are of PORT side of engine.
The first photo shows the (unusual?) petcock in the Osco exhaust manifold.
The second photo shows the exhaust manifold elbow with a brass? (or bronze?) "pipe plug." I have been advised to use teflon tape on these plug thread, to extend the life of the threads and to make removal easier.
The 3rd photo is the block drain petcock. That black tube on the right is the dipstick tube. It's 0.4" I.D. -- will accept 3/8" tube for oil extraction.
Drain plugs and petcocks -- starboard side
Above photos are of STARBOARD side of engine.
The top left photo shows the Osco exhaust manifold and the engines water-cooled oil cooler below. The engine's (white) fuel filter is on far right. The (original) fuel pump's sight glass has been removed.
The second photo shows the PORT side of the STARBOARD exhaust manifold "elbow" with its drain plug.
The bottom left-hand shows Osco manifold with its (unusual?) drain petcock. The water-cooled transmission oil cooler with its drain petcock is below. Looks as if someone has tried removing the large plug from the elbow casting.
The bottom right-hand photo shows the water-cooled transmission oil cooler with its drain petcock.
