Re: 90hp inline 6 mariner not peeing
It takes more than just a few seconds of running to fill the entire block and get water out of the telltale.
If you feel the water discharge coming out of the prop when the motor's running, and it's warmer than what's going in, water is circulating through the block. Also feel the exhaust cover (large, flat cover on the Port side of the engine). It'll get hot very quickly if water is not circulating thru the powerhead.
So, you see there's a few ways to determine, in the absence of a telltale, whether you have water flow.
Your telltale may just be plugged up or merely not running long enough to see flow. You can give the telltale a blast of compressed air and this will usually clear any obstructions. Severe cases may require pulling the hose off the telltale and maybe even the powerhead, to check for blockage.
When you're running on the flusher, apply enough water pressure to spill a bit of water past the muff 'ears'.
Once you start the motor, the spillage should diminish, indicating that the pump is pulling in water. Turn the water pressure up a bit more, so that with the motor running, a bit of water spills past the ears.
This will ensure that the suction side of the water pump is positively flooded.
