1974 85hp Evinrude water pump

[twgoff]

I have a 1974 85hp Evinrude that does not seem to have a piss tube to tell if the water pump is working. I can not find anywhere on the block, heads or body of the lower cowan where one would be. Does any one know if this engine had one and if it did not, how I could tell if the water pump is working.

Some years had the overboard indicator others did not... yours probably didn't. If there is no hole in the cowling you probably don't have one.

There should be a fair amount of water coming out of your exhaust pressure relief ports at idle and even more at speed... keep in mind when you initially start the engine it may take a second for the midsection to fill with water before it starts spitting out the relief ports. If you are at all in doubt of your water impeller or it hasn't been changed within the last 3 years you should replace it.

yours does not have one, but it can be added.

For the 1/8" tapered pipe thread tap, it requires a finished pilot hole using a letter R drill bit.
