Offset and cav plate height
I looking for advice from all who know about these things , I am about to have the transom beefed up a bit due to a previous owner cutting the transom down to accomadate a short shaft engine , my engine is a long shaft and we have run out of transom to put it in the correct position it is also not mounted true so we have a slight list at certain trim angles .
What I need to know from all the experts is the correct amount of offset (do I ask Humber? ) and where should the cav plate be in relation to the bottom of the hull ? Above level or below?
The new transom will be made from welded alloy sheet with suitable infill material to restore the transom to it origional shape . This will enable us to re drill the holes as at present it looks like swiss cheese with so many holes that have been filled !
