Greetings From out in the Marshall Islands, I am refitting a Ramus’ (1975) engine – the standard Volvo with a Yanmar. Cannot seem to find any way to connect the new 2inch hose onto the old exhaust thru hull which is 2 5/16. I don’t want to replace the thru hull if I can get away from it since the transom is already painted! Anyone have any ideas/sources? Thanks,Jon
