HB and voltage regulation

[Skidz]

Hey guys, I'm about to get a new fish finder for the boat and I was wondering what would be recommended to regulate the voltage coming into the unit. My old finder would say 'voltage high' when I was at WOT, and I have read that a regulator is needed to keep the voltage at the proper level.

Any ideas or suggestions as to which one to get?

Thanks,
Skidz

What kind of motor do you have?

2000 Johnson 25 hp. It doesn't have a regulator built in.

I would check with your local marine dealer for what they recommend. Just make sure that the amperage rating is higher than what the current draw of the unit is.
