I am looking into buying a new 1650 Fish Hawk. I will mainly be using it for trolling but also I don't want to be so under powered that it has to work too hard. For a manufacturer I've settled on Honda. Do you think a 60hp would do the trick or do you think a 75 would be better? My biggest concern is with a 75 it wouldn't troll down slow enough. It will be used 95% of the time on inland lakes but once in a while when the weather is good maybe out on Lake Michigan - not too far. Thank you in advance.
