Volvo SX Trim sending unit test and replacement

[Yawnsky24]

Picked up the new boat this week (204 SSi 5.0 GXi SX drive). During on-water checkout, the trim gauge stayed in full up posiion. Dealer rep and I both assumed that sending unit needed adjustment but did not have wrench that fit sending unit bolt. Dealer rep suggested returning it to shop for repair, but due to scheduling I won't be able to get it to the dealer until later next week.
Since I am fairly technical, I checked the adjustment last night and it seemed to make no difference within the bolt adjustment range. I then removed the sending unit and turned by hand. I could get the gauge to go to full down at the far end of the sending unit range, but any movement in the up direction brought gauge to full up.
I am trying to order service manuals, but they will be a few weeks. Do any of you have the resistance ranges that the sending unit should send secondly, I did not look well, but how difficult is it to route the wire through the outdrive into the engine compartment for replacement?
If not too difficult or requiring special tools, I would rather have the dealer rep drop of the sending unit and replace myself (they are willing to do this if I desire).

Thanks, Jan "Yawn"

Here is how you test and adjust it.

This is how you take the wires thru the transom shield.

Don,

Thanks a ton for the info. Hopefully if the rain stops I'll check it out this weekend and let you know what I find.

Welcome aboard Yawnsky!
Good to see more NC boaters.
What dealer are you using? Are they offering a free repair? I would let them do it. 8)8)

I may have given you information for the wrong drive. When you said new in your original post, I assumed it meant new to you. Now if this is a new boat with the SX-A drive on it, then the information is for the wrong drive.
If in fact, it is an SX-A drive, there are a couple of service bulletins on the trim gauge and sender that should be addressed. This will have to be done by a Volvo dealer.
Have them check out service bulletins 44-5-17A dated 10-2006 and 44-5-19 (same date)

Don,
It is a new SX-A drive and yes the dealer will take care of it, just thought that if it was just sending unit replacement that I would do it myself and save a trip. I will bring it in to them and let them do it. Thanks for all of the help!

Gary,
We bought the boat from Boats Unlimited in Raleigh/Durham. They immediately offered to take care of the problem, I just could not bring it back in after the delivery due to scheduling.
We live in Mebane and Boats Unlimited is the closest Chap dealer to us. So far they have been great to deal with and I can tell you a 35 mile trip to the dealer is a party compared to our first Chap which we bought from Park Boat in Washington NC. They were good to deal with, but a 2.5 hour 1 way trip on a good day. We loved our 1991 1800SL and although we looked at lots of boats before deciding on the new 204 we only test rode a few and the Chap won out easily based on our past experience with Chap.

Thanks for the reply!
