Had a major gear failure gear failure in my E series lower unit.Lools like finding parts is going to be hard.I am going to put a standard AQ 1:61 lower unit on the boat.the boat is a barrel back 18 2+3 has a small block chevy approx 375 HP. I ran a 14.5 + 23 RE mazco left hand thru a 1:45 ratio with the E drive. The best it did was 73 mph at 5200 rpm.The question is what props are available for the standard lower unit.Any information would be appricated!If you guys dont know nobody will!! Thanks
