I have a 16 foot semi deep v aluminium boat with a 50hp honda and a 2hp honda super loud kicker. I like that kicker very much except for the noise. I often go in shallow water and the 2hp is great because I can go slow and the cost to if i hit the propeller is very low. I would like to replace it with something quieter, what do you suggest? My transom is 20" With the honda bf2 i was able to go at 5.6 knots easily.
