My first one (75W-24-60), that Terry now has, was fairly quiet... they do have a good "werrrrr" sound to them when turning and the the annoying beep.. beep.. My new 70 inch's turning motor is louder than the first one. Gonna have a boo inside it when I get a day at the lake. 3yr guarantee on everything.. so no rush. Lifetime on shaft, and that's a good thing we've already found out, as Terry shattered his on a stump and got not only a new shaft.. but most of a lower unit/new built in sonar etc for free and fast service. Make sure your motor is mounted out far enough that the shaft has clearance from the gunnel... so the top unit springs can do their job and not have the gunnel as a pressure point.
