Thread: Help

30 seconds should be long enough for it to start pumping. It won't be pumping a lot of psi but I would think it should be pumping within that amount of time. Typically it won't start pumping immediately on a cold start.

Does your boat set out? Could be other things as well, check the pee hole and make sure it's not clogged. Wasps and other things like to nest in there and clog that line up.

Worse comes to worse they're relatively simple to change yourself, lots of places to get step by step process. A mechanic is going to charge you $60 - $75 per hour plus the part.

pee hole is clear took hose off and can blow air through

My merc takes longer than that to start peeing, especially on a hose.

Mine pees just from hose pressure without being started

Never troubleshoot your outboard cooling system off a set of muffs. They ain't designed to be run on muffs. Some motors will pee just fine, and some won't. Before worrying something is wrong, dunk the motor proper and see if she pees.

thanks for info

I always turn the hose up to full when doing the muffs. Can't have too much water.

As long as you have the muffs over the water intakes and there's no kinks in the hose and such, you can run it until you feel uncomfortable putting your hands on the cylinder heads. Harbor Freight also sells an infrared digital thermometer for $20 that is so accurate, you can see when the thermostat opens and closes. I've used mine many times to check my thermostats.
Good luck,
