Not sure of his thoughts.
Jim Dyke used them in there race program
Said you had to drain the water from the case
Constantly to keep bearings healthy.

Merc has down shafts internally.
Weismann does NOT run down shafts
Everything runs in line... No weak points.
Mercury bands everything Weismann makes
Because it works better.
Weismann was the first to drysump and were
Banned. Shared there design with Mercury and
Mercury changed it to a partial dry sump.

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

The rules are for the most part merc out drive only and believe me merc loves this more than anything as it gives and projects the feeling of superiority in the market. Why is this this way you ask, because the racers themselves are so ignorant and fearful that they approved it. When the Aussie team kicked butt in kW the racers were quick to ban the boat and the setup as they were afraid to put it simply. No one wanted to build a new boat they said to convert to a different setup so it Was easier to eliminate the issues than to face it. Resultant of this is that everyone thinks the merc is the only thing as that's what the racers use when in reality they believed that originally themselves but then realized they couldn't face their fears and made a rule change. Kinda like religion in the old days.
