I recently purchased a 1988 O'Day 322. I am very pleased with the boat. But the boat seems over prop'ed. Can I ask those of you who have an O'Day 322, what your prop size, manufacturer is, and it's performance and you happiness with it.
My prop is the factory standard Michican Sailor 14x14 two blade, which yields 3100 rpm max throttle. The the Yanmar 18 should give 3600 rpm at max throttle with the prop engaged. Clearly the boat is overprop'ed.
CDI Prop recommends their 15x11 (15 diam by 11 pitch) which seems like it would bring the RPM up a bit and add power. Same engine in an O'Day 302 recommends 15x10.
