I managed to get buoyancy aids and all that stuff sorted, and took the boat out for her first trip today. Unfortunately within about 30 seconds of leaving the river banks, the shear bolt went and that put an end to our trip for today! Unlucky of course, but could have been alot worse.
I'll let you know how it all goes after I've done my next trip, which will hopefully be a successful one.
I have posted in the engine part of the forum, a question about where I might find the nearest shop which should stock the shear pin for my engine (2.3hp Honda BF).
If anyone has any info about where an outboard spares stockist would be in the Herefordshire/ Gloucestershire area, I would be very grateful!
