Gear case drain plug washers

[pman7]

Can a pack of oil drain washer/gaskets be purchased from iboats? I'm going to buy a couple of the drain plugs and I'd like to buy a pack of washers to have extras but I don't know for sure that I see them listed.

This would be for a 1971 Merc500.

Do the magnet plugs do any good?

TD, any opinion on the magnet plugs?

absolutely necessary,for bottom plugs. they collect the little shavings, and if a problem big chunks of metal.. sometimes the first sign of trouble.

One more question TD. There seems to be some question whether or not the magnetic plug will fit my 71 Merc500. Technical Service at Iboats didn't know and Sierra doesn't know.

The Oldmercs.com site says the following:

"Magnetic Gear Lube Drain screw used on many models 1975 and later. Can also be retrofitted to earlier models which use the 10-79953T2 screw if there is at least 11/16" of clear depth available in the gearcase from the gasket surface."

I suppose I can go ahead, measure my clearance and give it a try but I'm curious if you know within reason whether or not it will fit mine and will it do any damage if I measure wrong?

The Sierra part number for the magnetic plug is 18-2375. The plug without the magnet 18-2244. My original parts list Mercury number for the non magnatized plug is C-10-28634.

i have no idea, i guess it you buy one plug and install it and rotate the lower and everything clears you are good. it's cramped quarters in there.

That's what I'll do.
