I have had 4 Yamaha engines (2 50HP, 1 9.9HP and 1 25HP all 4 stroke) on the various boats I have had. Some of those engines replaced OMC engines that came with the boat and I re-engined them. I love the Yamahas. I have found dealer support to be great, parts easy to find, very reliable, I love the freshwater flush port that doesn't require running with mouse ears. I don't think I would ever have an OMC. The Coast Guard used to use OMC engines when I was on small boats, but that was well before the Hondas they use now. We always had boats down. Just my plug for the Yamahas and I can't say I have ever even been on a boat with a Suzuki, so just my two cents on what a great engine I think the Yamaha is.
