Keep in mind that there may be a problem with your wiring/battery contributing to this problem. I am assuming you are basing your judgement on high boat voltmeter readings. This engine only has a 6 amp system, so it’s not likely to cause a high voltage/overcharging situation unless there are no other boat accessories used, or perhaps the battery is under-sized for the application. Check the battery connections/wiring, high resistance could help build up voltage in the system. Be sure to check the battery acid levels, low levels will cause high voltage as well.
Needless to say, there is nothing wrong with adding the regulator kit others have spoken of, or just turning on the lights while traveling at high throttle settings, as Casey mentioned. But, just wanted to mention other problem areas, a bad battery/low acid levels could explode.
One final thought I should have mentioned first….You dash voltmeter may be inaccurate.
