and when was the last time you checked the valve clearance??
A few thoughts
Well there's what I'd say is normal vibration from a running engine. The engine moves a bit on the mounts, meaning it's not rock solid, it shimmy's at idle more than a car engine if that helps.
The only thing I would say is that when I shift into reverse to decelerate, after pausing in neutral, there's a shrudder and then it settles down. There is a variprop 3 blade on her, so I assumed the shrudder is normal as the blades move into reverse pitch, but....?
Also, you can see in the video with the transmission engaged that the stuffing box and shaft move ever so slightly. Not a vibration, more a swaying motion. No idea if that's an issue...
I also seem to find a couple of cups of antifreeze in the bilge, and the overflow bottle is empty in the spring after the winter. Engine is full of coolant, and I just top it up and it doesn't happen during summer months. Can't figure this one out. I've tightened all the hose clamps I can see.
No I don't think the valves have ever been checked for clearance. I know I haven't done it in 3 years.
Sorry, there's a number of points here!
