Model 406B64R Serial B4246

40HP i believe, 2 stroke, twin, manual start with non toothed fly-wheel.

I would like to know year, HP, cc, what series?

Also, does it have a thermostat & a tell-tale as I think it overheats. I have removed the impeller and it look old, but ok.

Any help greatly appreciated..

Your model number is for a 1976 40HP Evinrude.

You will find the parts catalog on the BRP site: http://epc.brp.com/default.aspx?brands=ej&lang=e

Thanks for the quick reply. No match on BRP site. Do you know if this would have a thermostat?

i looked at the diagram and parts list, and did not see a thermostat in the crankcase diagram. i believe you have a motor made in the Belgium Plant. the diagrams an parts should be the same.

The models in the parts catalog sites have slight variations like rope start vs. electric start or long shaft vs. short. Find the one that best matches what you have. Both linked sites above show the same models.

If you are going to work on the motor you will want a factory service manual. The following link is a very good deal on a used one: http://cgi.ebay.com/ebaymotors/JOHNS...ssoriesQ5fGear

There is no thermostat on a '76 40hp.
