I have a Yanmar
3GM30F. Last checked the gear
box fluid 1.5 years ago or so, and was right where it should have been on the dip stick...just under the groove. Checked again tonight, and was barely registering on the stick. Is it normal for the fluid level to drop, needing occasional top offs, or do I have a leak? No fluid visible under the box or engine
runs fine. A bit worried because have not ever changed the engine
feet, and seems it vibrates a lot. Perhaps blew a seal with vibration?? Planning on replacing the feet next month during haul out
. Any thoughts?
