Ok I have a cmc p-130 trim and tilt unit on my 18 foot jon boat.  It only works sometimes.  I can hear the relays clicking and even bought new ones and still only clicking.  Sometimes it goes up fast and other times very slow.  What could be the problem with this and any ideas on how to fix it?  Thanks for any help.

I have no clue what type of lift that is or if it is an electric lift or an electric pump.  But if the relays are new and clicking then the problem is in the lift itself.  My guess is either the wire connection to it is corroded the motor is going out electrically or some bearings are going out or dry since it does go up fast sometimes.  Also make sure you have a strong enough battery.  If it is hydraulic check the fluid and the flow.

Sometimes clicking and chattering relays are an indication of a problem with the ground circuit.

ok it is the motor on the unit.  took it off and put outboard back on the boat.
