Boat Repair/adding gear oil

Question
I have a 1988 four winns with an omc cobra outdrive. Should I fill the gear casing with oil by squeezing from the bottom; the traditional way. Or is it just as good to add it in the top where the dipstick is? Curious.

Answer
Cobras are a little different than most outdrives.  Most outdrives are filled by taking out the vent screw at the top and filling it from the bottom until it comes out of the top.  A cobra drive is filled from the middle screw in between the upper and lower gear cases.  It should be marked fill next to the screw.  Take out the top dip stick screw, leave the bottom screw in and fill through the middle until you get the proper amount on the top dipstick screw.

Basic boat motor mechanics or boat wiring. I can help the most on mercruisers, merc outboards, and johnson evinrude outboards.

Experience

Mercruiser tech. Started working on boat motors three years ago. I have limited shop time under my belt but have proven myself in our shop and am now the shop manager.

Organizations
I have a mercury tech number and a yamaha tech number if you would like, but i don't think that being a certified tech makes you a good diagnostic pro.

Education/Credentials
Three years of see and learn shop time. Two weeks of tech training at Mercuiser school at Springfield. Two update merc schools at Topeka KS. "gotta love George". Tons of "E" skills classes online. Most of my ability to diagnose came from shop time working out problems.
