Odd problem

Hi All
My sailing club has several ribs that I look after ,all with honda engines.
Recently a couple of people have complained that they have had an electric shock from the control box of a 2008 honda 40 (carb model).
I just told them that they shouldn't be wearing their wifes underwear under their dry suit !
But the other day it happened to me (and I was wearing a wet suit)
As there is obviously only battery volts dc to the control box I'm thinking that there is perhaps an AC feed from the charging coil that the tacho runs off ?? I know that the tacho is plugged into the control box,and the shock only happens at high revs and is continuous not just a one off jolt like static discharge when you get out of a car.
The tacho works normally and the engine is running fine.
I asked our friendly local dealer that has supplied all the engines and he says that he's never heard of this.(and yes it is under warranty but it means swopping trailers and towing it 15 miles for them to look at)
Any input welcome please.

Check all the connections, on the tacho and any other electrical connections on the remote !!
