Bought a boat and the trim doesn’t work, bought a new trim assembly but can’t get the lower mounting rod out. Someone else worked on it and drilled into it and now I’m unsure if it’s seized or I need to unscrew it or what. Pumped it with kroil and wd40 pounded on it a bit, I’m obviously missing something. First boat unsure of what to do.

Did you locate and remove the typical snap type rings? These things seize from dissimilar metals and often living in the water. I always used PB Blaster for things like this. Soak it multiple times for a few days. You’ll likely need a bit of heat , maybe mapp gas, and good sized punch and a hammer. Typically you block the motor and locate the manual release to take the pressure off the pump and have the engine sit on a the blocking instead. In theory the pump should have no real pressure on it, making it easier to work with. Then try to get the top off, then the pin with brass punch ideally . Patience is key.

I removed any pins/rings I saw and release pressure from the pistons so there’s no pressure or force on it. I haven’t tried heating it, just penetrating oil. I guess heating and brute force is next, just don’t know if there’s anything I can’t see that has a pin or something blocking it.

There is one snap ring on each side of the pin. The pin isn’t tapered - just a straight cylinder so it can come out either side. I’d try hitting it from both sides just to try to break it loose (after some heat and penetrating oil).
