Tilt stops working as soon as I get back to the trailer...

I have a 1984 Renken 18'4 Cuddy Cabin (950) with a mercruiser 898, and I believe an Alpha 1 out drive. A few weeks ago I got stuck at the dock after a great day on the lake, my tilt switch wouldn't work. Several kind boaters tried to get the outdrive up with no success finally a boater took off the pistons at the drive and we lifted it up and tied it off. Got my mechanic to look at it and found the solenoid had gone bad, replaced and worked like a champ..

Two weeks later similar story...fuse was blown at the solenoid (but not the dash fuse?) replaced fuse, still nothing. Frantic call to mechanic who very kindly walked me through jumping the posts on the solenoid to get the drive up, (Thanks again Wes, you're a lifesaver!) This was not an easy task as the posts face the rear of the boat, so it was really blindly reaching a screwdriver into the darkness right in the most fuel smelling rear of the boat..scary but it worked.

So Solenoid is good, fuse is good, power is there...but no up or down tilt or trim? Where do I start troubleshooting? Believe the mechaniic is coming to fix her, but I hate feeling stupid when it comes to my boat. Are there any books, on-line resources, schematics, troubleshooting charts, etc. that any of you can recommend? I'd love to see the wiring diagram of my boat (I was in electronics for half my life) And would really like to have the equivilent of a Chiltons manual for cars for this boat.

Thanks for being here, and I appreciate al the help so far.

Side note; please if you see someone in need of a hand at the ramp, if you can't help at least be understanding of their situation. I am sure they (me) didn't mean to inconvience you getting your boat out of the public ramp quickly so you can rush back home. Screaming "get your damn boat out of there people are waiting!" is not going to speed the process up...I was doing everything I could...

Was that at Hemmingway by chance guess?:eek:

Too many possible guesses. My "gut" feeling is that if you are blowing the fuse the hydraulic pump motor is dying and drawing too many amps.

I second that.;)

if one is jumping the posts at the solenoid, then you can't rule it out as the culprit...as you're bypassing it all together....

Not sure what your abilities are with using a DVM, but here is a troubleshooting chart that may help you understand your trim/tilt system and find the problem.

Look at the last few pages of the .pdf file I posted.

You might try putting the shifter handle into gear and seeing if the trim works. Engine doesn't need to be running, just move the handle.

Thanks everyonde for the posts, I have been sick with the vegas nasty (colds here are the worst) for a couple weeks and haven't taken a look at it yet. Going out right now to try to troubleshoot it.

Thanks again!

Thanks again everyone, turned out to be over my head. My Mechanic (Thanks Wes!) took care of it very quickly. Turned out to be a shorted trim limiter, so he bypassed that circuit. I no longer have trim (which never really got used anyhow) and have tilt operation at both the tilt switch, and the trim switch. Works for me!

BTW I was wrong when I said it was at hemingway...I was at boulder ramp when this happened. My apologies.
