Small amount of water getting

Small amount of water getting into lower unit. Manual says tighten both upper and lower oil screws and "gaskets". Don't have any gaskets or even "O" rings in sight. Also could be seal around prop shaft I suppose. Ronny
 
"Drain lower unit, re-install

"Drain lower unit, re-install one of the screws (drain or fill), then apply 7 to 12 psi of pressurized air to either the drain or fill hole.

That should reveal the leakage area by sound and/or sight."
