Currently has a 13.5 x 20 Raker. It's a little crappy (not horrible) out of the hole and does okay on top end running around 5300-5500 rpms. Not looking for strictly speed but not looking to sacrifice any either to get a bit better bottom end. I'm thinking 13.5 X 19 maybe? Anybody know what a popular size/pitch is for this engine? No jackplate, just the 6" factory setback built into the transom of a 17' R70 Ranger. Normally just me and not a lot of gear in the boat.
