Rasing the deck, question about stringer height.

[hobiepilot]

Hi Guys,

Just started renovating a '69 SF20. We are going to have the deck self drain out the transom, and need recommendations on how high to raise the stringers to keep the scuppers out of the water. On previous threads I have seen guys go anywhere from 2in to 4in. 4in seems like we would start losing gunwale height, but the last thing I want are the scuppers being too low! We are putting a Yamaha 150 HPDI on the transom, weighing 475#'s. Any guidance is much appreciated!
