Where as the Yamaha has thousand of parts.
A 9.9hp is probably a good solution for powering your cat, but I'd be concerned about the weight if you ever plan to use it on your dinghy
(which I'm guessing is reasonably small) as 50 kg is a handful ashore and you'd need a outboard crane or similar to lift
it on/off the dinghy
If being able to use it on the dinghy is a requirement then maybe you could consider the Tohatsu Sailpro: http://www.tohatsu.co.uk/tohatsu-mfs6-sailpro.html
Easy to get parts for and at 6hp and 26 kg it should be fine on the dinghy, especially if you bring along a (standard) high pitch
prop for use on the dinghy.
It's possibly underpowered as an auxiliary for the cat (depending on where you sail, and what your expectations are for an auxiliary.....)
