Marine engine
Does anyone know about this type of an adaptation of a 59 AB for use in a boat? I am curious about the crankshaft end?

Re: Marine engine
I would say the extra pulley or pulley's on the extended shaft were to drive a sea water pump to pump water through a heat exchanger and into the marine exhaust manifold. The adaptor looks homemade to me. A heat exchanger has engine water running through it moved by the stock water pumps with sea water around the tubes the engine water runs through. A typical heat exchanger for a small boat would be about 5"s in diameter and 14"s long. On a some harbor type tug boats there are 6" channels welded to the hull for almost the entire length with engine water going through them and the water outside cooling them. Years ago a tug boat company called in freezing weather and asked if I could build a machine to melt the ice in the channels which froze. I made machines for plumbers for homes. To melt the ice on a tug boat the whole hull would have to be warmed. Also had a call from a resort out west that had a 3 or 4" pipe 5 miles long frozen. They would need cables 4"s in diameter hooked up to the Hoover Dam. Just old memories. G.M.

Re: Marine engine
That looks like something that was adapted to a 39-40 crank pulley in place of the fan.

Re: Marine engine
I had a 53 Ford flathead with a marine transmission on it in my ski boat. It used the Mercury bell housing and the transmission bolted right up to the flywheel end. The flywheel stayed on and there was a stub shaft that bolted onto the same bolts as the flywheel used to bolt to the crankshaft. Most factory marine engines are mounted in the reverse position, meaning that the flyhweel is on the forward end of the engines. The flathead does not lend itself to mounting this way, so they are mounted with the flywheel on the back end where the reverse gear is mounted. The pan was standard issue. The exhaust manifolds are water cooled by an exterior pump or pumps in the case of the V8. The water is then exited into the the exhaust pipe after a goose neck that prevents backflow of the water into the engine. If you need parts to build one, there is a company in Hemmings "Not Auto Related" section that buys and sells old marine engines and they may carry some of these parts. I have seen flathead marine engines for sale in Hemmings.
