auto pilot pumps

Anyone know of a pump that runs quieter than the B and G?
On one of my old builds, (sailing) the pump noise is driving them nuts
Any suggestions? pump has been insulated from hull so we have done all we can there

Hey mate, try the one from Raymarine, it is quite acceptable.

These guys supply a number of the big brand names with the kit, so probably cheaper. (Goiot and Jefa amongst others)
