On Engine Coolant Tank:

a & d . Water intake hoses
These hoses ran out through the hull and down the aft end of both Sponsons. At the end of each hose where it entered the water is a v shaped intake nozzel. Water is forced into the hose and up into the engine coolant tank. There is a T connection so when the tank is full
pressure will reverse the flow and force the excess water out through outflow hoses b & c.

b.& c Excess water outflow hoses

e. Hot engine water return to coolant tank

f. Cooler water return to engine

On Oil Coolant Tank

I. Cool water pickup
This hose exited through the hull on the port side only and had the same type of metal V shaped water pickup.

h. Excess water outflow hose. Vented out side of hull

j & k Oil lines to and from engine

Anchor Felt that he could save about 15 lbs and warm up the engine coolant water to reduce the shock of the very cold lake water hitting the engine. He eliminated the seperate Oil Coolant reservoir and combined it into the engine coolant reservoir. The tank walls are 3/32" stainless and the top and bottom are 3/16". the Tank measured about 10" in diameter.

a,b,c,& d serve the same function as described above. The hoses were approximately 3/4"
Aeroquip. They are connected to a T connection that allows for two way flow.

e & f Engine oil hot and cool return lines

g & h Engine water hot and cool water return lines

The important addition to the system in 50-51 was the Micarta Bearings
lubricating Line. This allows water to be forced into the key and main strut bearings.
As you might imagine once Slomo IV got up to speed the strut and leading edge of the bearing were out of the water , so Anchor devised this system to force feed water
to lubricate the bearings.

Line "I" indicates the bearing lubrication water line leading aft
