Force 15hp water in lower gear unit

[pecheux]

This outboard motor had not been use much (less than 25 hours) since it was born (1997) and had not been used at all for the past 3 years.<br /><br />bought it freshly tuned. like new mint condition. I know the ex owner.<br /><br />After using it for approx 8 hours both at WOT and trolling, I decided to change the gear oil for my personal curiosity and found a few drops of water to exit followed by the gear oil.<br /><br />Are there any additives that can be added to the gear unit in order to tune the seals ? Or will using it weekly cure the seals ?<br /><br />Tx

Nothing will cure the seals, but perhaps it is only the gasket on the fill and vent screws.<br /><br />Replace the gaskets and fill it up with lube.<br />Inspect for water intrusion after each of the next 3 outings.

roscoe ... Tx for the info. Is it possible the seals would dry after 3 years storage ? ANd if so could regular usage cure it ? (I hope ...lol)

Best to replace them, when the seals dry they crack and thats where you get H2O intrusion. Seal kits are inexpensive but you may need to get a seal insertion tool. I don't have my manual in front of me so I can't tell you what the part number is for the tool. Any merc dealer can get you the tool. I see seal kits on eBay all the time!
