I have an 1988 17 Custom , had an 85hp Evinrude that came on boat when new . Repowered in 2009 with 90 hp Yamaha 4 stroke . Plenty of power , but handled like a dog , transom sat very low in water , plowed bad at lower rpm's (pre-plane ) . Took the 90 4 stroke off , put on my pontoon , bought new old stock Yamaha 2 stroke 90 hp , and now the boat handles like a Porsche . Cruising just above idle speed , the boat sits flat in the water and does not plow . Gas tank (24 gallon ) is mounted under console . Both motors 3 holes up . Much quicker to plane off . I have run that motor ( 2 s ) like a rented mule and it has been FLAWLESS .
