Mariner 60 hp 1984

Hi all

I have put my new impeller in the new case and give it all a good clean . Put the muffs on and started the water supply. When I started the engine I expected the water to just come from the tell tale hole but it was coming from the hole and looked like the exhaust aswell as the two small holes at the top of the leg at the rear. Is this normal or have I got a problem


Regards Neil

All normal.

Water pumps up the water tube, into the plate under the powerhead. From that plate, part of it is routed to the two vent holes at the rear top of the leg (this is an "early warning system" to let you know the impeller's pumping even before the tell-tale starts). The rest is routed through the powerhead's cooling jackets, and eventually out the tell tale. Some of the water from the powerhead drains down through the leg, and that comes out the thru-prop along with the exhaust.

Thanks thats a relief . What sort of jet should I expect from the tell tale a small dribble when on tick over or a good high pressure jet .

I do not understand what you mean by "on tick over." Does that mean "while cranking with the starter"?

What you should see is:
Within a few seconds of starting the motor, a misty spray from the two vent holes at the rear; water will start coming out the thru-prop almost immediately, too.
After maybe another 10 to 15 seconds, some slight dribble from the tell-tale while the powerhead's cooling passages fill; even more water out the thru-prop.
After a few more seconds, tell-tale will become stronger as the passages become full, maybe at first looking like it's "pulsating" a little with each impeller fin pulse.
After a few more seconds, once the passages are completely full, a solid tell-tale stream that should hit the ground a good 2 yards or so from the motor.

Tell-tale should stay strong and steady after this. It will be a little stronger at higher rpm's (like if you go up to 1500rpm with the warm-up lever). If it is NOT strong and steady 20 or 30 seconds after starting, or if it "dribbles" or falters at any point while the motor's running, there's a problem.
