So, I recently purchased this outboard and I was told it has been sitting for several years. I started it up and it runs really good, except no water is coming out of the exhaust. So I naturally tried to drop the lower unit(to inspect the pump), but after taking all 4 bolts off and disconnecting the shift rod I cannot get it off. It wiggles a little but is stuck on the back side. Did I miss anything that would prevent it from dropping? Also, I checked the thermostat and it was stuck open, but that shouldn't have prevented water from pumping.
