This all boils down to user preference. In general racers will not use clutches because of extra losses in the drivetrain. Many sport boaters will opt for a clutch because of it's ease of use...ie: easier to launch, possibility to idle in position, etc...
The clutch will however require a water pump be installed in the boat for cooling the engine when the boat is idling (not moving).
Personally, for sport use I find a boat is much more fun with a clutch. :drinks:
