Anyone know where I can get some decals? I'm getting desperate now.
I think your best bet would be to write a nice letter to EP Barrus, quoting the serial number of the engine and enclosing the picture of the boat. If their customer care is half decent - I'm sure you can come to some arrangement to purchase a set of decals. Normally these can retail for over £100, given they can be quite complex designs on top-quality UV resistant vinyl, with a number of over-printed colours.
