Hmm Gasket wouldn't do much good. But Cav plate should be about an inch or so BELOW bottom of tinny in most cases. Sometimes more.
Normal 15in transom cutout suits motor clamp depth. Drop motor to sit on aluminium and tighten clamps.
Mine a 20 in. Does same thing.
Only some bigger motors when you racing etc do you play around with wedges.
Flush motor after EVERY trip if in salt. and replace impellor EVERY season. Regardless. (cheap insurance).
Carrying the old one or new one as spare. along with spare plugs and a file for when you scrape/snap off the bottom plate on gearbox. We all do at some time or other.
I popped a gearbox of a 30hp yrs ago in Coorong, coral bar, shallow water 25+ knots.
Thank god for Johnno 3 1\2 hp reserve.
we about 25miles from ramp at 3 in morning.
Some impellors come as a single item some come as a kit. or choice of. every coupla yrs if kit avail. Buy one. the salt corrodes everything and stainlesss sleeve makes it work better.
