The world of outboard motors has moved on apace over the last 50 years. As computers have developed and got smaller they have moved into every aspect of our lives. From the washing machine, to the car and even the mobile phones and cameras that we use every day. Computers are everywhere. The outboard motor is no exception either. On the one hand, engine management units give us improved fuel efficiency, but on the other hand failure of these units can cause breakdowns that the DIY mechanic has no chance of repairing. This being the case it is vital that we can have confidence in our supplier.
