I believe there was one in ski racing years ago but it was specially built and had a massive gill bracket on the back as the transom isn't wide enough. I doubt you will be able to convert an existing one though

Did the Gill bracket not cause issues with the massive amount of setback? With the amount of glassing going to be needed to strengthen everything up, having to widen the pit won't be an issue while we're there...

Saw a 20 (or 21?) over in Jersey some years ago with a pair on it (Johnsons I think).
Looked a beast...

Wow, that speed would be nice,   thank you all for the input,
So would I have to jack up the transom to put both engines on?
or would they still have to have the gill brcket?

Dude as i already said the transom / well isn't wide enough for twins on a P20 so you would have no choice but to run a massive gill bracket!! just run a single or sell it and get a 21
