Aqualoy A19 Marine Propeller shafts undergo more quality controls than any competing brand. These prop shafts are used in a wide variety of applications such as work boats, pleasure craft, naval vessels, and pumps. The Aqualoy® process produces a rounder, straighter, stronger shaft. All of our A19 shafts from 3/4" - 4" diameter are precision machined in our Mazak Nexus 350M CNC turning lathe to insure all machining is within .0005".

Single Tapered Shafts A19
All single tapered A19 stainless steel shafts will have a propeller taper machine according to SAE J755 specifications, unless other instructions are given. In addition to the propeller taper machining, a single square keyway will be machined for the coupling end of the shaft. The dimples for the set screws can only be machined with the coupling in place. If you purchase a coupling from us, there will be a $115.00 to fit and face the coupling to the shaft and during this process, the dimples for the set screws will be completed.

Double Tapered Shafts A19
All double tapered stainless shafts will have a propeller taper machine according to SAE J755 specifications, unless other instructions are given. In order for us to machine the coupling taper, we will require either a drawing of the coupling taper or the following dimensions must be specified(as there is not an SAE standard for coupling tapers and these tapers do vary); length of taper, small end diameter of taper, and length and size of threads.

Just order it!!! You'll be glad you did.
I will say that I grew up in a machine shop. My Dad was a Machinist in that shop for over 40 years. It's in his blood so much so that he bought one of the lathes and hired a crane to put it in his garage. And also has an xyz Mill. So he's still machining. The Deap Blue Yatch shaft I ordered was perfect. FLAWLESS. Keys, keyways, taper, threading... Spot on. Nice job. We received it pretty darn quick as well. Oh and pricing was even better. Pay for the fit and facing service if you're away from your home and your personal machine shop, it's worth every penny. I didn't. I fought that new split coupling and shaft for several hours, finally located a local Machinist and got it done. Great products. Super fast answers to questions... And there are no dumb questions. Thanks Mike !!! Oh I have ordered the whole left side of the menu with these guys. Top notch. Great prices, quick shipping, and excellent service, can't ask for more.

Experience Couldn't Be Better!
From my initial contact with Mike Heller to the moment I installed my new prop shaft, I couldn't have been more pleased and satisfied with my purchase experience from Deep Blue. Mike responded to my inquiry immediately and my order was shipped in four days which amazed me since I had a custom request for an additional keyway. I wish all vendors could be as responsive and professional as this company. Highly recommend!
