Has anyone tamed this beast? Had the motor mounts replaced by an experienced mechanic yesterday followed with a reasonably good alignment. I don't think the alignment is perfect but close. Had this done because the mounts are original and thinking that much of the vibration to the boat is due to the old rubber in the mounts. Unfortunately even with new mounts and another alignment, she's still a bronco in disguised even at idle. The mechanic suggested having the injectors rebuilt or cleaned. He's thinking is that doing this may smooth her out somewhat but that the Yanmar is what it is. My prior boat, Hunter 28.5, had a 2GM20 that was a very loud and jumpy but when I had the injectors rebuilt, it was like a I got a new engine! (it also helped in that boat to replace the 2 blade prop with a 3 blade prop). With the 3QM, am I looking for trouble doing an injector cleaning or rebuild? Has anyone tried this to tame this beastly machine with this. In it's defense, it is very reliable and gets me there and back every time. Any suggestions if the injectors are not the answer?
