I would point out that what is more important than HP is having the right prop. Most of these outboards come with a prop that is better suited to moving a light aluminum jonboat at higher speeds rather than the higher power, lower speed prop a sailboat needs.
Getting the right prop, so you can use the engine at WOT and have the power you need to keep the boat at "cruising" speed is essential.
How much does your boat displace? The typical rule of thumb is 1 HP / 500 lbs. of boat or so. I doubt your boat is 5000 lbs, so 9.9 is probably too much HP for it.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
