Design calls for 165 inch shaft, the shaft I'm talking about is 155 inches and 2 inch diameter.

A ship is safe in the harbor, but that is not what ships are for.

I changed the engine in my '53 Studebaker in about 1973. The machine shop would cheerfully shorten my driveshaft, but not lengthen it. (I had the pieces to make either happen...) Must have been a reason for it.

Being a cheap b**tard myself, saving money is always attractive. But, a lousy $1k to do the job 'right', after how many thousands for the rest of the project?

Larry that's the cheapest AD prices. Considerably higher for your size boat/engine. I hope I didn't imply it was necessary. Certianly isn't. I don't have an AD and have no intention of putting one in my present boat. I put the AD in my last boat.
And now that AD's patent has run out there are several similar alternatives. But if I had a bank roll and was building a boat I'd include an Aqua Drive. And actually after you get the AD installed it simplifies things.

Sorry but if you are building a new boat why frig about to maybe save a few dollars to end up with a redneck job , just do it right, get the new shaft made to suit.
Job done, no hassle AND if you ever go to sell the boat, no problems.
