I saw my first "T" engine outfitted for a marine application. The engine was fitted with a hand shift marine transmission most likely forward and reverse. The casting appeared to be a factory assembly and is very substantial. Built in to the transmission unit is an oil pump as there was no conventional oil pan or fly wheel-mag assembly. The oil pan, engine mount unit is a flat section of heavy plate steel with four mounting holes in it. The engine was fitted with an electric starter however it was attached to the front of the engine where the flywheel was attached and sits open with no cover. There is a conventional distributor and single coil for ignition. It is unclear as to how the cooling was done as the water pump was missing. The exhaust and intake manifolds were installed inverted so as to direct the exhaust vertical through the roof and the carb was mounted directly over the hot manifold, a little bit of a concern. There was a small dip stick in the transmission to check the oil level. To change oil would require a pump. The entire assembly was a substantial looking unit unlike usual marine conversions.
Do you have any pictures?
I do have some photos but I will require some assistance to post them.
