As for the Pee problem, either run something through the pee hole, make sure its not clogged. More than likely, you need to replace impeller.

I don't know how trim and impeller have anything in common other then voltage, but I would start with wire through pee hole try and see if dirt dobber is in nest, end with making sure you didn't melt the impeller..

Trim tilt start withpressing trim up helping motor up, top off with fluid lower raise top off lowerraise top off etc try and see if you have milky fluid(water intrusion/could mean salt intrusion) and or bubbles, end with pulling trim motor and cleaning it up and maybe changing out the brushes and contacs and cleaning with brake cleaner or something then bench test re assemble and resealing...

I am having issues with my trim and tilt rn zuk df175 and I have damn near rebuilt and replaced both of them and still having issues trimming up under power. I may just say screw it with this stimulus check n get a new ptt manifold and see if that fixes it.. really pisses me off IV disassemble both of them blew out with clean air and still won't trim up under power... Very frustrating and im about $1800 in with new gaskets and parts so far.i have been advised that the gaskets around the Rams may have deteriorated and gooten stuck(or some small salt crystals) in one of the passage ways and it's impossible to clean out...

Idk what else to do.. either

I had the exact same issue with a 200 Merc. My issue was a relay on the trim unit. I believe it has two, one for up and one for down.

Put a length of trimmer line in boat for this, probably relay on tt.

First, I would say that those hose earmuff things do not always maintain a solid pick up of the hose water (I have to physically squeeze them constantly to make mine pick up). Secondly, I would get piece of weedeater line (heavy mono) and feed it through the pee hole as far as you can wiggle it in there to check for dirt or other obstructions (keep it in the boat for when you go through some mud). Third, If you determine that you just have bad flow, I would get a barrel so you can run the engine with recirculated water and vinegar. I did this two times on my Yammy 150 because I kept overheating. The vinegar dissolves a lot of salt/dirt deposits in the water jacket. On the trim, I would start by greasing the rams and running the trim up and down several times; use white lithium grease. Good luck.

Trim is knocking because you need grease on the top of the ram where it hits the striker plate.

If you haven’t changed the impeller in a few years, best bet to just go ahead and do that. Or just change the whole kit if you never have, not that much more. Just did my lower unit seals, oil and water pump Sunday. Knock while trimming is most likely where the rams hit the striker plates. I put never seize there and it cures that.

Stepped into the shed to grab my phone and noticed the pee stream was less then it went away all together. In span on a min or two.

Check the ears on the hose make sure it’s sealed well on the foot of the outboard. Also check for kinks in hose reducing pressure.

Happened to me recently on a Yamaha 2 stroke and it was just the lack of sufficient water pressure to push the water up to the impeller
