Looking at the Weston UK Marine Engine site I noticed that their range of marine engines have water cooled back plates. See: http://westonuk.co.uk/westonuk2_101.htm

Anyone come across water cooled back plates before? Any major advantage? Any opinions?

Can't get the link to work on my fone but found the site.
Anyone on here using Wundabond?

Yes I've got a old OS max 10 & 30 with water cooled back plates.
Don't know of any advantages thou

Water cooled backplates will improve overall efficiency. The charge through the carb goes via the crankcase & up into the ports. By cooling the backplate you'll increase the charge density increasing the performance. A side benefit is that if the exhaust is that side then you'll reduce the temperature gradient across the cylinder which improves the piston fit & reduces the chances of a hot seize.
