Mercruiser Tilt/trim stuck
 

On a used boat I bought recently the outdrive is stick in the up
position. The trim pump turns when the downswitch is pressed and when
the trailer button is pressed, but the outdrive will not go down. The
up switch does not work or turn the pump. The reservoir is about 3/4
full. The trim limit switch is not connected. Maybe it's wired wrong,
or the hydraulic lines are connected wrong, Any ideas? Anybody have a
wiring schematic or link it's an 86 alpha one. Thanks. Tom.

Mercruiser Tilt/trim port side unstuck!
 

Well after looking everything over I decided to drain the oil from the
cylinders by cracking open the fittings, and to my surprise the
cylinders still didn't compress! So I rotated the cylinder piston rods
and tried to loosen them a bit and after that the port side cylinder
works fine! Now I still have to work on the starboard cylinder to get
it to work. Halfway there anyway. I was thinking of trying a ratchet
strap to get it to compress.

The trailere switch normally raises the drive to the full up position for
trailering. The trim switch will lower the drive to the normal operation
when pressed for down. It will then adjust the outdrive up or down but only
within the normal operating range. The trailer switch has to be used to get
the drive fully up for trailering. There is a switch on one side of the
outdrive where it pivots that keeps the trim switch from moving the drive
too far up. The trailer switch bypasses this switch. The other side of the
outdrive pivot has the sending unit for the trim gauge.

You should get a clymers manual for mercruisers.

Sounds like you need to rebuild the cylinders. Mercuiser make a kit put you
may not want to tackle this work unless you are a reasonably good shade tree
mechanic. Check out Aftermarket Marine for parts

Perhaps it is because Ron is local to Aftermarket Discount Marine (they're
both in Louisiana), but the link below will provide you with my mail order
experience with this company.
