most likely a leak in the check valve in the cylinder or pump. I do not think there is a rebuild kit available probably cheapest to look for used trim.....
First thing change the o rings in the tilt and trim cylinders, if this doesnt help replace the valve body. Good luck, bret<br /><br /> If you need further assistance please email me @ forcepower01@yahoo.com. thanks,Bret
Search this site. The pilot check valves causes the leak down 99.9% of the time. You will have a pump with 2 snaprings or 2 allen head screws. These are the check valves which can be removed without removing the pump. The pump pilot check valve seal number is 820719 from Merc dealer.
