2017 Mondo - No RAW Water Flow Question

[Holdmybeer]

Check the ball valve on the thru-hull where the water is sucked in. If some how it got closed you will overheat quickly.

The water inlet is the lowest point in the system and the hose would have to push past the v-drive and transmission before water would be in the raw water pump. Follow your lines from thru hull up to pump.

A clog will cause this also. Most likely the heat exchanger. Remember if you are clogged upstream you cannot push the air out of the system to get fresh water in. 235 is scary but if that is all you got to, you should have avoided damage.

I see. Thanks. I just assumed the hose from the thru-hull pick up/inlet went directly to the water pump.

I noticed the ball valve handle when looking through the v-drive access hatch. It's currently oriented to be in line with the hose and doesn't look to have been touched, ever. I'm assuming it's in the open position in its current state.

When testing to see if water flows, I started the engine and it ran perfectly fine (only ran it for less than 30 seconds) but still no water getting to the pump housing from the garden hose via the under hull pick up/inlet.

The pump has to draw water through the v-drive first. It takes a minute before coming out of the exhaust.

Are youbgetting water in the bilge? Missing or loose plug would cause some issues also.

Got it. I was hoping the water pressure from the garden hose (using a fake a lake) would push water through the system and come out of the pump housing since I had pulled the cover and impeller. Instead, the water was just spraying along the bottom of the hull where the fake a lake meets the hull. I didn't see any water in the bilge area.

Ideas on the next steps? Start pulling hoses to see what I find?

Where does the heat exchanger fall into the mix? I assume it's also cooling oil so I would need to make sure I am pulling the correct hoses.

Where does the heat exchanger fall into the mix?
Follow the large hose leaving the V-drive and the next thing it connects is the transmission heat exchanger. Pull the hose off and use your finger to clean out any debris.
