I have the SW-75 (Saltwater version) on my 21 center consol. So far I could not be happier. It's got plenty of power, seems quiet to me and lasts a long time. The best part for me is the remote. The fact that I can run the boat from anywhere is great. Nothing like being in close to boilers in heavy surf and knowing you can run the boat while netting a fish or for that matter while fighting a fish that might take you around the boat. Never used it in fresh water yet. As far as the mount goes it seems solid as I have had it in some rough seas where we were getting full air and it never budged. I do agree that a lock would be nice and I think I may have that figured out. The beep is to loud for me, but It's nice to know I can use the old "nail through the speaker" trick to solve that. I have only used the foot pedal once and it was a little tough in choppy seas but seems like it would work fine on a lake. But never really plan on using the foot, as long as I have the remote, it's just to cool. Oh and at least with the remote, I think the ability to manuver precisely is there in a big way. I had my boat in Newport harbor fishing spotted bay bass and had no issues getting back in the docks and around the boats. Just my 2 cents from the salt.
