yup i used hardwood... and yup i recessed them..but i filled the recessed area with 5200..was gonna wait till it hardened..then sand flush with gelcoat and then cover with marine tex....while the 5200 is rubbery..think i should drill out the recessed area that has 5200 in it now and fill it with marine tex?
heres some pics..
jackplate with all corrosion removed, greased & ready to go...
