Yeah, and at over 40 knots!

Very interesting.

I'm not sure I believe this part:

In the high-speed scenario, the leg and pod will shear off flush with the
hull. The lower bearing carrier has been engineered specially to break at a
point below the O-ring seal between the fixed and steerable parts of the
drive. As the leg bends backwards, the vertical drive shaft simply pulls out
of its spline. The inside of the transmission is now open to the ocean but
no water can escape into the boat and the vital mounting joint between
transmission and hull will remain not only intact but undamaged thanks to
the energy absorption of the big twin O-rings.

Leading with the prop?

That should work well in the log infested waters up this way. (not).

I assume that Tiara will offer this as an available upcharged option, not as
standard equipment?

Every so often, somebody tries to reinvent the wheel.

And hearing how much parts for Volvo's cost, this should result in an
undamaged hull, but a really damaged checking account.

And, like most things that have Volvo stamped on them, incredible and
astronomic repair bills because the damn things are over engineered.

Tiara is going to use it.

Forward facing propellors with no protection eh?

That ought to be interesting the first time you hit something solid at 40
knots.

Oh yeah, I read the part about the leg shearing off and not puncturing the
hull. Uh huh. And if that seal fails? Exactly how big is that mounting
hole? Bet 'ya can't jam a wooden plug in THAT slot.

Wouldn't it also throw debris upward into the hull as well if it caught the
upward spin of the prop?

That'd be delicious.

Your leg shears off cleanly, but the drive unit flips upward and punctures
the hull on the way off.

Forward facing props unprotected by any sort of skeg, with the units
coming out through a hole in the bottom of the boat?

Fascinating!

You didn't finish reading Harry.

While I applaud any advances in technology as applied to marine
propulsion, I see a few points that really bother me.

1. Despite the review's attempt to sell this as equivalent in
simplicity and maintenance as a straight shaft drive, it has far more
parts, and more closely resembles an outdrive than a straight shaft
drive.

2. Unprotected props pulling the boat? Again they attempt to put the
reader at ease when the obvious question of striking an underwater
object comes up. But I doubt that there are any guarantees. If that
drive sheers backward at 40 MPH, what's to stop it from punching a
hole in the hull directly behind the mount? Even if the drive sheers
off as designed, it's not going to be a cheap fix.
