Have an AQ231A in my 89 baretta phaser 230 cuddy. What model stern drive came with this - 270, 275, 280, or 290? What is a good prop? I have a 14x19 aluminum michigan. Hole shot isnt great with a load. It tops out at 43 mph.
Impossible to say which model drive you have. There should be a tag on the upper gear box right below where the helmet attaches that should give you the drive model and serial numbers.
