300 HPDI on a 23' CC

[caboman22]

Hey guys...I'm new on here..Good info. My uncle has a 1998 23cc and just had a new E-tec 300 30" installed on her and said he's getting top end around 49mph. Not sure of fuel burn. I'm doing my research now for engines. I'm about to start the restoration on my 1974 Potter 23CC and looking at 350 verado, 300 verado, 300 optimax. Raising transom to 30" I have read a lot of great post on here. Both boats are from south Jersey. Good luck!
