Trimmable surface drive system?

[Robbi]

Hi there!

I was looking at Harry Schoells patented trimmable surface drive
at www.pulsedrive.com

I have seen another similar design somewhere, but I just can't remember
the name of the other drive system. Does anyone know what I'm looking for?

The ordinary outboard and inboard sterndrives are so boring. A boat with a jet or surface drive system gets immediately more interesting.

The new Mercury jet drive was a very compact propulsion system.
Does anyone have any experience with it?

Found it!

It was the DBD Marine at www.dbdmarine.com that I searched for.

Would be nice to try it out someday!

Does anyone have experience of the drive system?

I haven't driven either of these surface drives, but from what I've heard they are both rather sensitive to driver inputs and require very careful trimming. Better than sterndrives at the top end but harder to control on a slow plane. As for the Merc jet you mention, it's really not much more than a jet-ski pump with an Optimax powerhead bolted on top. Not particularly efficient but good acceleration.

I stumbled across Arneson's Bravo to surface drive conversion the other day.

I have a Pulse drive 1500 SS like new, low hours, priced new 14,500 USD, it is for sale at 4,500 USD, Interest?
