Tank and console location

[Barryc26]

I’m doing a rebuild on a 1977 17
Deck is off except for 2” flange all the way around- kept casting deck in place
Raising deck 3”
Putting in new 35gal Moeller
Will install 50hp 4 stroke
How far back from casting deck should I place tank in bilge?
How far back from casting deck should I place console?

Thanks

I have a 2000 17’5” center console, later today I could get measurements and post , there’s a 33 gallon tank and I have a 60 hp 4 stroke which does very well
