transom leak

[alldodge]

Not fully understanding the comments. The gimbal bearing is in the gimbal housing, and the weight of the motor is supported by the transom plate and the 8 studs. The gimbal housing is inserted with all studs in place. The transom plate is installed and nuts are torqued to 23 ft lb, then its ready for the motor

Dodge- guess what I'm saying is when the transom assembly goes back in, it's not going to be 100% where it was originally.And, it's more important that the motor is aligned with where the bearing is sitting and level to the transom assembly than matching the holes where the front motor mounts are. I can adjust the front of the motor up and down and make sure the motor is sitting on the inner transom plate correctly and the bolts for the rear should slide in and out easily. I should not twist the alignment of the motor to match up with the holes for the front motor mounts. I left the motor mounts attached to the engine. I want the weight of the motor 100% resting on the front and year mounts and not binding against the transom in any way that I can avoid. I'm having a hard time finding the part numbers on my trim senders- I looked on both parts web sites and it looks like they are showing the same one for either side with my transom serial number OW139887, what am I missing? It sure is not very clear. I find what I think i'm looking for on ebay, I can use the part numbers back on the merc site but it does not tell me which transom they are for and they are not the same p/n's when I look by my serial number, what is up with that??

If the transom assy does go back in slightly off from original this will not matter. The rear of the motor can tilted lower on one side and it still would not matter. The rear of the motor is fastened firmly to the transom plate, the front mounts are adjusted to match the rear mounts. The gimbal bearing will be in perfect position once the front monts are adjusted to the rear mounts.

Only thing that can throw this off is if the rear mounts on the transom plate have been damaged or have compressed in their position. The difference between where the gimbal housing was originally and where it will be on reinstall is negligible

The issue with the sender/switch is your not able to find just one or the other, you can only find a kit which contains a switch and sender. The part number is 805320A03

got ya, thanks!

don't know if this link to ebay comes thru, but, what are those two little wires for?? https://www.ebay.com/itm/Fits-Mercr...7JZmwJC:sc:USPSFirstClass!32773!US!-1&vxp=mtr

Those are for the trim limit/sender

 

[rickasbury]

nah, not the main wires...the two little short wires shown kind of at the bottom separat the bottom?

OK, couldn't quite figure what you were asking either.
Those are cable adapters, they change the bayonet to ring type terminals. The older sender wires use to be attached by terminal boards or screws and nuts.

 

[rickasbury]

ah, got ya, that makes sense....I guess these senders work for a variety of age/style out drives. thx

OK, so making progress getting everything cleaned up, got a boat load of parts and pieces ordered, couple of items yet to find and order but pretty much everything was ordered last week. So today, thought I would get the three parts cleaned and sprayed down, degreased etc. The one part I still had to get apart was the manifold for the trim- one of the hoses I could not get off, the one that goes through the transom from the pump to the top of the manifold and had to cut it to get it apart. I have ordered that hose. So, where the mercathode wires come through the manifold I could not really find a plug or part- there is a lot of corrosion I guess I would call in on that side- I did get the hose connection off and cleaned it up. But, where the wires went through, I just kind of dug it out with a small screw driver, was not a "plug" there that I could just pull out. So, when I get my new one will be anxious to see if it comes with what ever plugs and and what it looks like and if it will even seal. I did not want to get a new manifold mainly because getting those trim lines off looked like a real problem and I don't want to have to buy 4 hoses and a manifold if I can help it- any input what the plug was? I sprayed it down with penetrating oil and hopefully the corrosion will come out of it but it don't look so good,.....

 

[alldodge]

The wires just go thru without a plug. There is a O-ring (item 5) that goes between the Mercathode Anode and the manifold

[rickasbury]

hmmm...well mine must have been leaking some as it was very corroded up...wires I could not get out until I dug them out with a small screw driver. I do recall seeing a O ring, mine was not just a 0 it had a different shape but I do recall seeing both in the different manuals.....interesting! I will have to re evaluate the manifold I have then and make sure it is going to seal....thanks Dodge.

 

[rickasbury]

manifold looks fine..here is my mercathode and seal...looks a little different than what the book shows, assume they are the same and since I'm replacing it not a concern...guess also would not hurt to put some sealant on that rascal as well...don't know that it was leaking through but obvious it got wet from the inside if nothing else and corroded up pretty good...

site shows two different versions with the same pn?

 

[alldodge]

Your at a competitor site so no show

 

[rickasbury]

so....I think I figured it out....looks like there were two different versions of that seal....but, the mercatode has the wire harness with a plug that plugs in to the inside...how does that plug get thru the little hold in the manifold?

 

[alldodge]

Use a wire to fish it thru

 

[rickasbury]

Dodge- first my mercathode did not come apart all together as I had to cut the wire off, burned off some of what was left and a mess...I'm looking at the picture of the mercathode with a harness and a big connector on the end of it that, as near as I can tell but must be wrong, has to pass through the manifold somehow to get through the transom assembly and on to that connection....how does that happen, does that harness disconnect from the mercathode and then plug back in or something? I have not bought mine yet so perhaps it will make more sense when I get it in my hand...

 

[alldodge]

The Mercathode comes with 2 long wires and both have ring terminals on them. The ring terminals go up thru the manifold and then connect to the module. Here is the instructions for install

My research tells me that AD what is for the older units. When looking up part number of the latest MC part # for the Merc Cathode 8M0085692 I found a pic showing the connector ships off and is installed on the wires after being install through the transom. Just web search by the part number. I am sure it is in your thread but having the year/serial numbers help match the right version of the required parts.
