Not as much as last year. Life is shifting again so I haven't had the time or reason to put holes in the sky. We are really close to building a house & getting moved back to Wichita, which means a new boat is very close to being a reality too!

Gentry was the first to dry sump a merc drive, the #5 back then. Then the victory team just ran the #6 with little to no oil. Regardless dry sump concept has been around for a century
The vertical shaft has some advantages in your comparison also. Not saying it's not good but just saying don't believe the brochure 100% as there is a reality beyond the hype. The parasitic drag is minimal in comparison to the hydrodynamic drag. The Weismann looks more like a kaama

Truth be told Pat dry sumped the IV drive for Victory long before the VI. Drive looked crazy had hoses externally on the drive to pump the oil. And the reason Merc didn't do a full drysump is you have to modify the gimbal and run an internal oil tank.

As we speak my boat is being converted from Dry sump sixes to Weismann WMD's. The upper gears in the sixes do not last behind the turbines. Usually failing somewhere between 10 and 40 hours. I will let you guys know how it goes.

I'm planning a large project in the future. I'm going to sell the htm ss24 in the future. It runs good now 102gps with 650 hp. But looking hard at the nordic 28ss and putting my new motor in it. 1350hp on 93 and about 1700hp on e85. I think the WMD is the only choice. I just hope it will work well on a single engine 28cat boat like the 26 eliminator Daytona I have seen on the net.
