Hot Telltale

Hi guys, new here!
I've got a pretty weird problem with my 15hp evinrude late 80's or early 90's iirc.
It has had problems with cooling, the waterways were probably filled with salt residue, the engine was 99% used in the sea, it has been flushed out regularly, but it was sitting up for a few years due to lack of funds

The waterways were cleared with diesel by my mechanic and it worked fine for a few days, then it stopped pumping water again
I tried using a foot pump up the telltale pipe to force air through the system, and it is pumping water again, but if I have it running for about 2 minutes the telltale starts to get pretty warm, as does the block.I haven't had it running for any longer than that incase blows up!
The engine was fully serviced not long ago.

Any help is appreciated!

Hi Neil

Have you tried salt away not sure what the dilution is but you could run it for short periods until it clears just keep the water spout clear.

I've heard of it, but know nothing about it!
I'm guessing it's some additive you put in a barrel of water with the engine running?

Well I was told about it by Craig of costal pro seats to keep salt at bay works ok I used it on my 90suzuki at the end of the season as part of the service just to flush around in the test tank you will only know if it works for you if your problem gets better its worth a try before a strip down

Good luck

Thanks, I'll give it a try anyway, any idea where I can get it?
There's very few boat shops anywhere near me.

Impeller was replaced not long ago, I think the thermostat was removed to keep it cooler as it's an old enough engine.

Get a new one and put it back in.
Without it the water flow around the block may not be as intended.
