I am going to put new screws in the 2 drain and fill holes in the gearcase of my 1974 115HP Johnson this spring. Boat is in storage right now. Anybody happen to know the thread size for these ?

Go to a marine store and buy drain plugs for your mfger with new seals, cost about $10 for the two ( or three). The lower plug should have a magnet to catch metal flakes.

Not screws, wishin. They are plugs and special. Do as Jonesey advises.
