I was changing my...

I was changing my impeller on my outboard I had just purchased this year and have run into a problem. The motor is a 1990 40 hp. classic. after looseing the three nuts that hold the Lower unit togeather there was a forth bolt under a plastic cap on the back side of motor. I have tryed all different size sockets both standard and metric, and can"t find the correct size CAN YOU HELP IN ANY WAY.

Mechanic's Assistant: How many miles are on the car? Is it an automatic or a manual transmission?

NOT A lOT

Mechanic's Assistant: Are you fixing your Classic yourself? What have you tried so far?

I THOUGHT i EXPLAINED THAT IN MY FRIST MESSAGE

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No JUST ABOUT THE BOLT UNDER THE PLASTIC COVER
