not with the 2stroke, the you could probably get 5hp from the 4hp (same engine). The 5hp 4 stroke is the same as their 6hp, so you could probably tune that one.

I think that 16.4knts is a very good speed for a 2.3m inflatable anyway.

I'd try playing around with the engine height and possibly a coarser pitch prop. Good luck!
