Ok, I was jsut hoping for a quick reply. I noticed a guy a few threads down replaced the lower unit grease on his 4.3 Cobra and toasted his drive. He referred to draining it from the bottom and filling it from the bottom and it failed in five minutes.
According to my book, there are THREE screws on the starboard side for the lower unit grease draining and filling. The bottom drain by the skeg, the middle VENT and the top dip stick.
I open the top dip stick to get air and the bottom drain to drain it. Then, instead of the vent, I screw the little pump for filling it into the drain by the skeg and pump the thing full. The unit calls for 64 ounces and I make darn sure I pump 64 ounces into it.
So, am I risking anything pumping from the bottom instead of filling from the vent in the middle of the drive? Heck, when I'm done, the gear oil registers exactly full on the little dip stick so how can a guy go wrong? Unless it's me. Thanks, Bob
