Please can anyone Identify this

Looks like it could be a rectifier to me.

Looks like a rectifier to me, the right wiring for one although it doesn't look original to me I could be wrong though. There are a lot of pattern ones available that are perfectly good. I haven't ever seen one like this before myself. Remember what I said at Chichester though Rob, you don't need charging on your engine to keep it running - it has a magneto - so the battery is only to start the motor or power up any electrics on the boat.

Rectifier methinks.Though I couldn't guess what from.Yamaha mariner????It looks Japanese. Two yellow for the stator/alternator.Gray for the tach/rev counter,red +,all to the power pack.Is there a part number on it? Do you know what Mercury it came off?

Saw one of these advertised as mid 80s on Chrysler Force Mercury in the states.

Thanks all, for your replies
cleaned it a bit more and found these No's 817411 3191
So you were all right, (10 points each) it is a 9 amp Rectifier (Now there's an idea for the magazine?)

Unless you are a stickler for originality and rectifier from later model Mercs will do, you just have to connect the wires to suit.
