Coincidence or not, I just checked the oil yesterday and the level was midway between low and high on the dipstick.
As I was running late (as usual) I did not have the time to take cowl off and check. Tomorrow when I get gas at the marina I will check the level>
Any thoughts?? Engine is a 2009 Yamaha 150 4 stroke with maybe 200 hours. Tach was actually just installed a month or so ago by a Yamaha dealer, but it has worked fine.
