change gear oil mercruiser alpha one

[roffey]

This is my first season with the boat. I found the reservoir when I started to take boards apart when try to troubleshoot a trim problem (yahoo, a $80 switch will fix that problem). Thanks spareparts, I thought filling from the vent is a no no. You told me what I thought was the way to go. Correct me if I am wrong but the reservoir is an add on and is there to insure oil is always on supply.
