UV18 Silent Submerge for sale

I have Silent submerge UV18 + (2 inch longer) . Made in 2005 or so, Motor was replaced in 2010 by Rodney, so it is one of the fast ones turning 1400rpm. This is a last ones from large SS i have left. Ready to sell it :(, so it can see some caves..finally.

I can sell it with 40AH LiIO battery for 2200 shipped in continental US. Battery is nicely home made about 2 years old holds charge and have may be 200 dives on it.
If u dont want a battery deduct $300.

What is the recommended max continuous run-time on this faster motor before it needs a pause to cool off? A normal Gavin motor has always been said to overheat (start melting things inside) if you run it more than about 45 minutes on full speed in Florida cave temperatures. Would this have more like a 30-minute recommendation..?

Thank you,
Andreas
