Loosened the bottom screw on my 1958 Thunderbolt 40hp. Got about a tablespoon of pure water before oil started seeping out. Time to replace the oil!
How much time normally elapses before significant water forms in the gear box? This motor has not been used since 2005 by the way. Last started seven years ago.
So I ordered a new water pump impeller.
Is there a simple way to properly fill gear boxes without the kit? With ten outboards, six that need medical attention, figuring I should just buy a gear oil insertion kit.
EDIT: With ten outboards, a kit that worked on both Johnson/Evinrude and Mercury/Mariner would be nice. Have a Yamaha too.
I don't know what is wrong with these motors. Hoping to salvage several. Figure that water pump impeller and gear oil is almost automatic.
