First you'll have to establish whether you just have a rectifier and this behavior is normal, or if you have a rectifier/regulator assy and there's something wrong with it.

For motors with a rectifier, there's no regulator and although the output is generally limited to about 10 amps or so, with light load the battery terminal voltage will tend to rise. A good marine battery will handle this no problem.

A simple solution is to leave the running lites on which will provide enough load to keep the voltage to reasonable levels. Or, you can retrofit a rectifier/regulator assy, although that's rather $$pendy. It'll keep your voltage in check, although you still won't get more than 10 amps out of it.
