I think HIN numbers started about '72, plates before that - I wouldn't bother with the bracket without closing it in. Yes 20" transoms, mine has 2 5" starboard splash things on either side of the motor that help as I don't get much water in the splashwell. My Merc goes about 415# and the scuppers will let water in, I have a dive platform and 3 step retractable ladder makes getting in easy and the dog will get up on the platform, he goes alot.
