  • Trim Switch bad?

    Hello everyone. Well, Im 95% done with one problem. I did take the fish box out to get at that zerk fitting for the steering and I also rubbed grease on the steering ram. When I went to raise the outdrive to check for marine growth, the trim switch will work to lower the drive but when I tried to raise it....nothing. I think I hear a click from the transom when I try to raise but it doesnt raise. Any ides. It is a 98 CC25 Volvo Gas. Thanks.

    Check yor relays. There is one for up and one for down. I have had the same problem several times. The relays that Volvo use are prone to fail. You must remove the red cover off of the trim motor to access the relays. It is kind of difficult to get the cover off. There are three phillips head screws holding it on. The relays just unplug. Sometimes you can tap on the relay and it will work again. If this does not work you need to replace the up relay.

      Thanks for the reply. I was actually down at the boat today and I happened to jiggle the wires going to the trim pump. All of a sudden the trim worked again. Then it didnt work, so I jiggled the wires again and it worked again. I next proceeded to take the cover off which I have determined is impossible. Would somebody please help me get that cover off without taking off the 5" exhaust pipe or worse yet the jackshaft. We have a 1998 boat and the cover is white and somewhere in the neighborhood of 9"x9" and 3" deep. It will not come out. I think all I have is a corrosion prob that needs to be wire brushed, but I cant get in there. Tips??

        The cover will come out without removing the jackshaft or the exhaust hose. Some of the covers are red, some are white but they are all the same pump, and the same size, you just have to turn it the right way to remove it. It is a very tight fit. The first time I tried to remove mine, I also did not think it would come out. It will trust me. Some force is necessary to work it around the jackshaft, but it will come out without breaking anything. Sounds exactly like one of your relays is going bad. Sometimes just by tapping on the cover, or jiggling the wires, I could get mine to work again. I went ahead and replaced my up relay and have not had a problem since. Good luck!!

            Blackbeard....I am going to pick up 2 new relays because they are cheap enough. Any idea what the Volvo Penta part #s are. I know you said you replaced your up relay. I dug up #3858809 but wasnt sure if that was the right one. Thanks.

              DSmith 1178,

              The Volvo part number is 854357. You can go to www.marinepartsexpress.com and order the part. This site usually has better prices than the Volvo dealers. You can also go to some auto parts stores and get them to cross reference this number and match up the relay for you. I think Napa has them. The up and down relays are the same relay. One is for up, one is for down, but they are the same part number. A phillips head screw holds the relay in place if I recall correctly. Simply remove the screw and unplug the relay. Good luck!!

                Thanks for all your help blackbeard. I was finally able to get that cover off, you were right, it was a pain. I then found that the wiring harnesses on the trim relays seemed to have vibrated loose a little and the relays had some corrosion on the terminals. I wire brushed them off and put some di-electric grease on all of the terminals and reinstalled. She works like a champ now. I will order a new relay to keep as a spare. My father and I are also working on a modification to that trim pump cover to make is easier to get out.

                  most of the time you can simply cross over the relays volvo used to a bosch or potter and brumfield spdt relay at 40 amps, 12 volt coil. about 6 or 7 bucks at a auto supply house or go into any car stereo and alarm shop.

                    Thanks for the tip....would sure be cheaper than the $40+ that volvo wants for one of them.
