Strange twin inboard installation

Well not maybe strange but I've never seen it like this before. Can anyone explain how it works?
I pinched the photo off Pauls site, hope you don't mind?

Just had another look, are both engines mounted the same way and one has a shaft going to the drive?

Staggered

Simple really.

If you don't have the width to have the engines side by side but have plenty of length put one further forward than the other.

The starboard engine in the photo just needs a shaft between it and the sterndrive and a bit of extra piping.

Quite common on race boats and high performance "muscleboats". Typically a V8 petrol engine is wide but short.

Cheers mate, seems like a win win situation, ok you lose some space but you gain lots of access to both engines in a narrowish hull.

Do you think it'd work on a SR lol?!

Other reason is to keep the weight in the centre of the boat for stability and drives closer together shares the stress on the drives when flying the boat
