Just bought a Johnson 4.0 Deluxe that was intended for use on my inflatable. However, after a test run I think I will put it on my sailboat and use the Yamaha 4 (currently on the sailboat) for the inflatable.<br />The Johnson seems to have more guts and is definitly quieter than the Yamaha. (perhaps because it is a twin?<br />Any comments to this?<br />My questions are What is the difference between a Johnson 4 and a 4 Deluxe?<br />What year would it be?<br />The model # is cj4rdhce<br />Than you in advance.<br />Great site!!!
