I have a 1976 seahorse 115 hp which is stuck in the up

Customer Question
Hi, I have a...

Hi, I have a 1976 Johnson seahorse 115 hp which is stuck in the up position.i have installed a new tilt trim motor, it's full of oil and if I unbolt the tops of the 2 outer Rams they open and close fine. I am not sure what the other 2 cylinders between these do but I suspect that the left one is stuck in the open position. What can be done to restore function and does this motor have an up lock somewhere I haven't found. Any help appreciated regards Paul

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the Marine Mechanic should know?

I have also loosened the large nuts on the long bolt from which the motor tilts and this does not seem to be stuck.

Chances are one of the check balls in the valve body is stuck. Did you notice any water or corosion in the unit when you changed the motor?
