My Islander 32 MKii is on the hard and we are in the process of changing the thruhulls(head inlet/outlet, engine inlet, and head sink drain) does anyone have a good supplier of thru hulls besides the usual suspects? These thru hulls are flush-mounted and it seems that the flange diameter is larger than the Groco/perko etc. the flange diam is 2.75 on a 1 inch thread and 2.25 on a 3/4 inch thread. Any help would be appreciated.
