1973 20' MA - New Bracket, Self Bailing Deck, etc.

[plusone876]

I currently have a 2003 150 Merc. saltwater series efi on an armstrong bracket (enclosed transom). Currently my deck is not self-bailing and that is my main concern as I fish offshore often. My batteries are under my console, so there is not much weight to move forward. My scuppers go straight out through the transom. I am debating on getting a hermco flotation bracket (maybe one for twins) in order to capitalize on the aft flotation benefits. I am also debating on getting a four stroke while I do this reconfigure as well. Any advice, suggestions, concerns, experience about the flotation bracket, what four stroke to get, weight distribution, re routing the scuppers.

Thanks in advance!
