Hello, I am new to the Forum but it looks to me like a great place where boaters help other boaters.

Problem: I recently bought a 2000 Maxum 1800sr (3.0L Mercruiser) in great condition. Everything has been fine over the last few weeks, she runs great. Anyways the other day we went out in the Gulf and it was very choppy, so much so that we decided to head to the backwater, but not before we ran aground on a sand bar with the trim almost all the way down (we were going very slow, no other damage, but the lower unit definitely hit the sandbar). When I went to raise the trim it was stuck (no up or down, just made clicking noise). So we limped back to the dock, and luckily it wasnt all the way down so we were able to trailer it. My friend (who's good with boat engines) figured out that we had torn loose 2 wires from the trim motor. Just by touching them to the trim motor we were able to raise it up. Now we cannot seem to find where these 2 wires are supposed to hook into permanently to the trim motor. (looks like no place for them to hook into anywhere on it). Worse, however, is after we got the trim up, we went to flush the engine and it would not start. (battery is good becuase all other things worked blower, radio, ect.) So bottom line is I need to figure out where these 2 wires attach to the trim motor, and also we must have done something messing around with it to screw up the ignition, since it wont start (i get nothing, doesnt try to turn over, makes absolutley no noise and does nothing when trying to start) Unfortunately my boat guy went back up North, and I really need some help (do not want to take it in to repair). I see so many of you helping out other boaters that I feel like this is the best place to ask. Any help would be GREATLY APPRECIATED!!! thanks.....

I'm trying to figure out how you could dislodge trim motor wires by hitting the skeg. Do you have pics?

Well I'm not sure that I did, but there was just 2 loose wires that looked liked they ran to the trim motor (i will take another look when i get home and tell you what color they are), and when we touched them to the solenoid the trim worked again. So maybe I could have done something else? (the trim motor is very loose in the engine compartment, but my friend said thats normal with saltwater boats.) I will try to take pics tonight and post them tomorow. Thanks a lot for the help, this forum is great...

When you turn the key on, do the gauges come to life or is that dead also? Have you checked the main circuit breaker on the engine? There is also a square fuse mounted on the starter terminal. If you shorted something while messing with trim wires, that would be "the" place to check.

Thanks for the response Oracle. Yes, the gauges come to life but thats it.

Thank you so much Oracle. I used your trim motor manual to make sure everything was connected correctly, and after checking everything I had 2 blown fuses, one for the Trim and one for the engine. My boat now starts and the Trim is working correctly thanks to you guys. This forum is great. I do have another question though: The 2 loose wires coming from the engine I mentioned earlier (one is black and grounded to the engine, other is red and I can't see where it goes. They both have the little metal ends like they connect to something (this is why we thought that they came off the Trim motor, but now I'm starting to think they don't do anything. The reason we thought they had something to do with the Trim is because when it was stuck, we touched the red wire to the Trim Motor and it started working again. I would like to know where these go (if anywhere), but at least boat is working properly. Thanks so much and if you have any idea about these wires I would love to hear them.

Hi, and thanks for the help. I don't have a picture but there is a black wire that looks like its grounded coming from the engine block, and a red one coming from deep in the engine somewhere, and it looks like they might have slipped off this little square box thats actually attached to the top of the engine compartment. I'm thinking this is the cause for the motor shutting off when I use the Trim. Please help..
