DF175 No water from Pee Hole

[mitch]

sorry for being late but did you check the water pressure relief valve as well could be stuck open ?

there is a plug at the top of most engines that you can remove while engine is off. turn the water and muffs on, then remove that big plug , then crank engine. it will flush out the problem that everyone says will cost you thousands to rebuild. flush it out....the top. thats what its for.

The rectangular muffs needs to cover the intake screen as usual but it also needs to cover the two holes (on each side) about 3 inches next to the intake screen. The muffs I have seem to be a standard size so if they make one that is 1" longer, problem solved.

Glad you solved your problem. But for me, that's not been a problem. My rectangular muffs do NOT cover the two holes on each side in front of the intake grates, but cover only the intake grates themselves. When I turn on the water, it shoots out of those holes in front and also runs out of some holes at the front bottom side of the cavitation plate. But still, the motor pees like it should immediately on startup.

Do you think there's a crack in the water pump housing? I've read others having similar issues on their DF motor.

Don't really know, brother. Do you have any means of monitoring actual water temp, such as the SMIS gauges? I flush mine for 10-15 minutes after it levels off at 150°, knowing that the thermostat has opened when the temp reaches that level. I'm reading my engine functions on my Garmin chartplotter via the NMEA 2000 network.
