Part number for a thermostat kit for a Lark III?

[mr-asa]

Is there a kit for the thermostat replacement? Do you just replace the thermostat and gasket?
’61 Evinrude Lark III, 40HP, 35525

Where do you guys find the kit numbers anyways? I can never find actual kits, just individual parts.

Just the thermostat and cover gasket. Unless some genius removed and tossed the black housing and check valve.

Don’t forget the rubber thermostat seal also, yours is probably worn/damaged…

You are so right Frank, no rubber gasket around the thermostat. The gasket is under the plastic check valve cup….D
