TOPIC: Tell Tail Tricks?

Hi everyone,

I just purchased a 1970 Glastron V-143 with its original Merc 1000. I'm pretty sure it’s a 1968 version, but am still working on confirming that as I'm in Australia, the serial number says it’s a 1000SS (based on US numbers), it does not have the “SS” over the “1000” decal and the main decal colour scheme ("MERCURY" in red) does not match anything I can see from 1968 (or any of the years either side).

I put the hose on it and gave it a 30 second run at idle, but no tell tail. I am planning to replace the impellor and do a few other things, but I'd like to give it a bit more of a run first, to test out what I will need to actually tackle.

So, my questions is… are there any tricks I can do, to try and get the water at the outlet, and/or to test if water is actually cooling the motor?

Thanks,
Aaron

touch the exhaust cover it should be no more than warm to the touch.

Bugs, silt,sand etc can all plug the tube, I usually use a blow gun off my compressor to ck for obstructions , it will most likely need a pump anyway. post a pic so we can see it.

Aaron, A red decal set is what my 1970 1350 has. For as little cost and trouble an impeller is, and the havoc that not pumping water can cause, I think I'd put one in before running the motor for more than a few seconds.
A V143 with a 100 HP Merc 6 will be a pretty sweet little rig!

The early Mercury motors never had an overheat warning indicator or a shutdown system for overheat.

Not sure why any classic motor owner would take a chance on running with an iffy impeller.----Put a new one in every 3 years !!!
