The old motor died on our recently purchased Catalina 25 and we are looking to purchase a new one. Any suggestions on 20" vs. 25" long stem? Also, would appreciate any motor brand recommendations - we are looking for a 9.9 hp, 4 cycle for less noise and pollution. Finally, any recommendations on easy to lift motor brackets? The one that came with the boat is hard to lift. We would like to use the existing thru-hull holes to mount the new bracket. Any suggestions are much appreciated.
