I can see very little on eBay - is there a source of discount Mercury parts in the UK ?
Best to talk to a dealer, eBay didn't explain that i needed two terminator plugs, one on the engine side, second one one the junction box to make it work properly ...
Got good advice and prices from McAleese marine NI
Ring John for good advice
