The jack plate just allows you to add the 25 with out filing the transom, but if you are going new, you will not need.

Tanks are stock and one size

I sold my V20 3 years ago, and bought a 23' Sea Ox wa, thats what I just put the 225 4 stroke on, and it weights 600 pounds +!! Not close for a V20!

IMO your 225 is way over kill, and not needed, a 150 will have all the power you will ever need. with out the weight and gas your going to use.

Also make sure you get a good bilge pump and a second one for back up, that boat is before self bailing decks and all water goes to the bilge.

Last unless you are a real good glass guy, I would go from the inside and leave the out side alone. Or use the pourable stuff.
I am not a glass guy at all so I am no real help there.

Good Luck
