Hello everyone, I purchased a boat with a 1991 115 Merc on it. Purchased without lower unit and now have one on the way. New problem is that while playing around with the motor I realized the tilt pump is dead. Tried hooking pump directly to the battery already. My problem is that it is stuck in the down position. Am I missing something on how to get the pump out so I can get one on order. (Can't order a new one until I get the numbers off of the current one.) Is there a release somewhere on it? Do I need to relieve pressure somewhere? I have the motor off of the boat now as I bought it for a replacement for my boat. Please help. Somewhat lost here. Thanks.
