Not a "Big Al" but, a 21,000 series engine with a water cooled exhaust manifold.

Ok. Please share how you can tell the difference.

Someone should buy the tug and have refitted into a yacht. I've seen it done before.

Nothing is impossible if it is properly financed

That one's been up, a while, must want too much, fer it...

Big Al was the truck engine. The vast majority made were the 25000 engine and very few (almost none) were the 21000. They were painted either purple or dove gray. Engines painted purple went to Frieghtliner and the ones painted dove gray were shipped to Kenworth. No engines from the Harvey engine plant were "private" sale. All were sold to Frieghtliner, Kenworth or warranty replacement.

At the Harvey engine plant there was a department (department 76) called Commercial Products. That department outfitted various engines for commercial use as ordered from AC dealers. Some engines were ordered for use in a marine environment or a closed in space and those got the water cooled exhaust manifold. As I remember the engines for marine use were sent/ sold to Gray Marine.

In the mid 70's I was the inspector in that department and a unit couldn't be shipped till I inspected it and passed it.

ACJack, I really appreciate your shared knowledge & personal AC employment experience - Thank you. I have only read that AC marketed the 6138I(25,000), 6138t( 21,000H), 6138LT(17,000), 670t(3500), 649t(2900), & 433t(2300) engines for trucks(only a few engines - 6138 & 670?) and commercial (marine, mines, generators, stationary PU, pumps, etc..). I belove the 670 was offered for small delivery truck engines. Was there any other engines offered by AC for truck and/or commercial marketing??
