How do you find the 9.9hp? I've come across a 9.8 tohatsu which is another option... any feedback on the Tohatsu would be welcomed.
Before I got my current SIB I had an Avon S250 (70cm shorter and 15kg less than your S300). With the 9.9HP and 2 onboard it would plane quite happily.
My current SIB is a quite a bit heavier than yours. It would still plane 2 up with the 9.9HP, but it took a good few seconds to get on the plane.
Now with 15HP, it is noticeably quicker to plane.
I don't have any experience of the Tohatsu 9.8HP, but a browse of the forum would indicate that they are well thought of.
