Hi guys..need a fairly fast answer on this...pulling my hair out...even after reading other posts with similar issues.

we have a 888 ford 302 in a glastron sierra (1975 I believe) serial in the 4's. anyway... trim goes down fine..motor sounds fine...won't come up. checked the oil...filled. checked the switch..its getting power.. no clicking when i select up. looks like a single solonoid..and I really don't have time or money to go buying parts..any way to run a jumper to swing the motor in the other direction..for the time being??

I can lift the lower unit (grunting of course) by hand...but its gonna get old fast. I don't have the chapter on troubleshooting this from the merc book..only the first 5 chapters...grrrrrrrrr

Re: merc 888 trim not going up

I had the same problem with my boat but it is a '96. It has 2 separate selenoids. One for up and one for down. I had someone activating the up switch and down switch and I used a multimeter on DC to see what was happening. I found that juice was getting to one side of the up selenoid but not going through it. I saw on the down selenoid how it worked when activated so I knew where to jumper it. I did while my help activated the up button normally and it worked...with no blow fuses. :)

good luck

for any interested...i did get the drive up..but had to jump the up connection to the red (positive) connection on the unit... works well..for a temporary fix. im prob out to get a solonoid this week.
