MHZ has been constantly backpeddling about the power capabilities of the S6 drives. Once they were thought indestructable with a Rotax Max 125cc cart motor driving a pair through a gearbox. Since those days I think it is anyones guess what an S6 will take.
The Hunter my buddy Phil built with the inline 70 was a touch overpowered. While the S6 drives were working hard - the power reaching them was also being run through a splitter box at a 30% overdrive (if my memory still works). Which to my understanding would mean the drives are seeing at least 30% less power though more RPM.
If I were tacking a hunter build I would think an inline zenoah/RCMK or blata/polini a good way to get her moving. She wont break any speed records but should certainly have some authority on the water.
Here is a link to Phils Hunter -

I have a MHZ Reckless which is a little bigger than the Hunter - powered with a pair of zenoahs to a pair of S6's - another way to go. Wish I could report how well she runs (I have yet to get her wet I am embarrassed to say) - some pics from Thomas' build may also be of help -
