I am running the upper half but solid bottoms on 800 + HP
But my boat doesn't jump out of the water much.

I would not use those in anything over about 450hp unless you bolt them to something like this

not really = not handy
They are just bigger
again my boat is a cat so it doesn't jump big waves like my Scarab did.
But I had the same mounts on my Scarab without any problems.
I solid mount my engines. The mounts on my Daytona don't have any rubber.
That and I have the rear mounts locked down so the engine can't twist or move.

the feet walk even on the stringer mounts Grif posted. The torque of the engine is one of the contributing factors. - Rough water is another, also harmonics of the engine and so on. The bigger the torque of the engine the worst it is on the feet -

Feet = what the OP posted in the pic
