I have been looking at a lot of pics of Gray 4 cyl engines and I have not seen one where the distributor actually sticks up THROUGH the head.

Do you mean that it actually mounts on the top of the head or do you mean mounted straight up out of the crankcase just to the rear of the cylinder block?

If the former, does someone have a pic?

The standard contintal farm/industrial engine has the distributor sticking right up through the middle of the head.If you look close you can see the the round casting mark where it would go on the grey marine engines.Apparently grey wanted the engines shorter so on the ones they used the distributor has been moved to the rear either laying down or standing up.I don't have pictures,but there are plenty on farm tractor sites.i have an engine here or go look at the drake tail at CMM.

I cannot pass up a coment on Larry's comment on the "Drake Tail" hull at CMM. There were actually two common names for that hull style around the Chesapeake bay. It depends on what area of the Bay or its tributaries what these nifty hulls were called. In the northern area of the Bay they were called "Mule Hoof" Sterns and in the lower portion of the Bay "Drake Tails". Myself I learned "Mule Hoof Stern" having spent years around the Annapolis area. To me the stern design looks just like a horse or mule foot. As I understand the basic hull design they were long and narrow hulls which permitted at slow idle with an NR-1 or ZR-1 a crabber with little need for agressive steering to follow a trot line picking up crabs as the line passed over a roller fixed to a midship plank sticking out from the side about 18". The rollers were often discarded wringer rollers from old wahing machines. The aft section of the hull was designed to keep the hull from squatting in the water when underway. These hulls are no longer common on the Bay and like a lot of industrial tools they were great for the intended purpose but not much good for any other use hence their demise. I will say that trot lining is a great way to catch crabs if there are any to catch which has become another sad story of pollution. Curent speculation is this will be a good year for crabs. I hope they are right as the last few years have been a disaster. I was told a few days ago Good crabs are going for $150.00 a bushel. A long ways for $10.00 a bushel thirty years ago.

Well, I saw a little Clark forklift yesterday and lo and behold it had a Continental motor in it with the distributor coming out through the head. The cast-in number on the block and head were F400. The rebuild tag riveted on the block said "Model: F4124" and "Make: Conti 1262".

I have a couple of Express 244s with the distributors mounted aft. However, the location where it would go up through the head has been filled with a take off for a mechanical tach. Yes, straight up through the middle of the head.

It was common for the distributor to drive the oil pump, so if it was moved they still had to have a rotating shaft there, a nice place for a tach drive.
