I remember Mastry Marine had designed an inner transom match for Yanmar diesel to a Bravo drive some years ago. In fact, there used to be a cat with this setup in Key West that would take 10-12 passengers on a tour around the island. Seems like it ran 60-ish?

Re-inventing the wheel?
The Yanmar engine has an SAE industrial fly wheel set up. There has always been off the shelf parts to hook up SAE industrial flywheel set ups to Bravos.

The boat you are refering to is the Sea Rocket. there have been 15 or so built so far, and with the exception of the first two that were not built as sea rockets,we have been involved at Mastry with all of them. These boats all run 6LPs and bravo ones. The boats run in the 55-60 range.
To answer the question about the sterndrive package for yanmars, yes Mastry is the one who created that package. We had a casting made for a sterndrive bell housing that would allow the 6LP to mate with the bravo drives. We have also done a few boats with the 6LY engines and bravos, however those engines really have too much tq for the bravo drives. The only real success we had with the LY bravo combo was in a 36 Spectre cat with 2 speed transmissions and bravos. The boat ran just over 100 mph.

That is one of the boats we did about 2 years ago, if I remember correctly.
stirling, I know we used to have a casting that would bolt the LY engines to a bravo inner transom plate.
29firefox is right there is a way to adapt the inboard version of the 6lp using a jack shaft setup, or we can covert them over to a sterndrive application.

It will be "accurate". Just "proportionally" lower. Just mark the zones on the gauge so the operator can understand whats going on. I use automotive decal vinyl around the outer edges of the bezel it sticks to the glass real good. Operators don't always read the numbers on gauges right. Anything important like oil pressure, coolant temp, pyrometer etcetera get some green, yellow and red so the operator can tell at a glance what his status is.
