The livewell overflow whether thru hull or not needs to be above the water line...at rest, underway, all the time, etc...

I recall other 170s leaking from the rigging trough on the starboard side of the boat. Also,as mentioned check all hoses on the thru hulls. Have you inspected the livewell to ensure there is not a hole or crack? Check the fittings in the livewell as well. I have also seen instances where the livewell leaks from the top where the inner tank and the outer shell come together.
If his thru hull outflow fitting is below the waterline, which i doubt...then livewell outflow would not exit the hull into open water. Simple physics.

Simple physics. I'm I misunderstanding something?The overflow drain "tube" as well as the drain/live well bottom are both above the waterline in my 91 therefore water will drain as long as the discharge point (thru hull) is below that elevation. Is the live well bottom in the 170 below the waterline on this model? I doubt that because you would need a pump to empty the well. As long as it's above the discharge point, it's going to drain whether the discharge point is underwater or not.
175 might have a livewell factory installed.
If the livewell drain is below the water line the livewell will still drain since the livewell itself and the water in the livewell are above the waterline. With that said if it is below the water line even with the livewell not in use there will be water in the drain hose up to the level of the water line. I would double check the hoses, clamps and thru hull fittings. I have seen the nylon thru hull fitting dry rot and fail just inside the hull. This happened to my buddies 215 Explorer that he bought. you could see into the hull thru the 2" thru hull fitting. And it WAS below the waterline.Problem is some of those fittings were plumbed BEFORE the deck was placed on the hull. So getting to them may be difficult or impossible. You may have to cut a hole and install a deck plate to gain access. I've been on a 175 but I haven't looked at how the plumbing was installed.
