I have a yamaha 25hp 4 stroke, and have had no trouble out of it. I have had it for 3 years, and it runs perfectly. I didn't realize they discontinued it. I had the starter get stuck on it 1 time, but it was an isolated incident. I do keep my boat/motor garage kept year round. I also fish a lot in the winter, pretty much all year. Outboard motors are always best when used frequently. If they are used 2 times a year, you would more than likely have a little more trouble. I love this 4 stroke. I would buy it all over again. It saves a lot of gas, too.
