My pressure guage stop working, it was fine one day then not working the next week. Sherm said it might be froze, but it was 70+ degrees that day it wasnt working. I check the hose coming out the lower unit and nothing was coming out of it. Is it possible for it to be clogged in the lower unit. Motor is still peeing as normal.. Any help or suggestions are appreciated..

The speedo tube comes out of the lower end.The PSI guage is taken off the block towards the rear.Some newer models have a hose already connected to the block and is simply hooked up from a hose somewhere near the rigging tube inside the cowl.

I checked that tube and no water was come out of it. I tried to even spray water into it to see if it were clogged up with debris or something. If no water is coming out then the gauge is probably ok, the problem is no water is coming out of that LW tube..

It could be clogged or a bad sensor on the engine block. Newer models have a sensor like the block temperature sensor on your car. They just plug into a wire and it feeds if you have Smart Craft. If you have analog with a hose you can easily check that line from the block itself and once you remove the cowling it should be visible on the lower or upper back of the block.

I have a 1996 Mariner EFI, no smart craft. I saw the hoses on the block, it was still peeing out of the telltale. but there has to be a block somewhere on the LW. Its cold out there today my water hose is frozen so I will check it again when warms up. Oh yeah I did let all the water out of LW before temps dipped last night..
