I have just purchased a 17ft day-fisher Dory type. It came with two engines an evinrude 50hp (model no e50belcta; serial no. b004108) and a evinrude 4hp (model no:be4brcde; serial no. b0033017)<br /><br />First question is what are the years of these engines?<br />Second - the 4hp motor start fine and revs up lovely for the first 3/4seconds then cuts out, dispite multiple attempts at different choke and throttle setting the outcome is the same - any advice?<br />Third - what is the optimum prop of the 50HP motor and this boat?
