Weird issue I have never seen. I changed all fluids last spring and monitored throughout the season with no issues with loss at any point. Changed the oil and filter in the fall and left the trans and vdrive until this spring. I got a 50 degree day today so I decided to crank the boat for awhile. After I ran it I checked everything and vdrive is bone dry. Any ideas where the oil could have gone? The bilge isn't oily.
