Tiara is going to use it.

This is going to be a nightmare. Look at the schematic and
read what will happen to the drive under impact.

Yeah - I really want the drive unit to break off and sit
on the bottom.

Are you sure it's not April 1st over in Sweden?



So, what happens when you hit a rock or log at 25 knots with an Alpha or
Bravo drive?

The drive and trim rams are designed to "give" backward to absorb much
of the shock. At slower speeds, you might get away with only prop and
skeg damage. Higher speeds have been known to punch a hole into the
nose cone. I also had a friend who had an unfortunate encounter with a
rock at high speed and it pretty much sheared the drive off at the
gimbal mount. In this particular case, water started to seep in
through what used to be the shaft bellows, but it was not enough that
the bilge pump couldn't keep up until we towed him in

But without that built-in "give", something WILL break.

Even with the give, something will break.
