Mallory Seal, 10' roll 9-78007

I put the Mallory Seal strip around my gearcase on my 1966 6hp Johnson Outboard motor. I used a line of hardening gasket seal also. I then refilled the gearcase with OB gear oil. No leaks seen. After fishing for a day at West Point Lake ( I caught 20 Channel Catfish and 9 Crappie), I checked the gearcase for water. No water at all in it! Also, I saw no leakage of gear oil into the lake. I am 100% satisfied that the seal strip did the job and my lower unit is sealed.
