Nice Classic

I need to know the exact floor heights that people raise floors. And do you raise it the same from front to back. Thanks guys

like to know the same question for a 74 23 sf???

1 1/2" has worked very well over the years on my 23 with rear scuppers hauling a big 4 stroke. Should be even better now that I'm going with side scuppers.

Id go at least 2 inches on a 20. from front to back.

Deck Height
 

I raised the deck of a 20' 1 1/2" plus the plywood I put on top bringing total height to 2" plus fiberglass. Boat had a 1999 Johnson 150hp. Deck was perfect at 2" height after using the "criss cross" scupper trick where the left side was plumbed right and the right side plumbed left.
