The R?surrection of the SeaGem

Re: The R?surrection of the SeaGem

I'm not sure, I would guess it is relay? Where is the switch in the circut?

On a side note, what software are you using for your engine calcs? Is it freeware or did you buy it?

Terry

Hey Terry,

I use the camquest software from Competition Cams, its free here is a link to it download it here

The controller isn't a relay I borrowed this definition from another site

"it is a solid-state device that operates off a boat's 12-volt battery and provides protection by impressing a reverse blocking current that stops the destructive flow of galvanic currents"

what I was questioning is that it looked like the PO abandoned it. I am going to have to re-wire it and test it out. It was hooked up to the bat. but the wires to the electrode was gone. I did find the electrode on the starboard side yesterday I haven't had time to play with it today yet cause I am catching up on some work work

Well Break over time to get back to work

Ahh I see. Goes to show what I don't know! I probably wouldn't stress about it if its a trailer boat. I think more about slipped boats having severe glavanic issues as long as the grounds are well sorted.

Thanks for the link! Downloading now!

Hey Bill,
On mine the black /white and the brown with purple sleeve or dot, Joined on an insulated block and the other just went to ground. The connection was the same as you posted but the block was just the connection point. A butt splice would have worked the same, just would not have held the wires in place.
Hope this helps.
Good luck
Bob

Re: The R?surrection of the SeaGem

Hey Terry, Glad to have been of help .
Don't feel bad on the Mercathode system, I had to look it up too. My other boat don't have one. Right now it is hooked up to power but the transom mounted Anode and electrode are disconnected from it. Its going to be a trailer-ed boat but I am going to hook it all back up anyway and keep my fingers crossed that it works.

Hi Bob, I cant find the brown/white wire coming from the gauge. I am going to look for it again this morning, never got to the backyard to work on it yesterday. I spent most of the day on a building automation system and by the time I stopped work my brain and eyes were fried from staring at a computer screen.

If I can't find it today I am just going to run a new wire right to the gauge. I want to get all the wiring cleaned up before I drop the engine in. The one thing I did see is that she doesn't have a Starboard navigation light, not even a spot where it was. I am wondering if that is that light socket I found just laying behind the stringer, I thought having one was mandatory

Re: The R?surrection of the SeaGem

Bill,
The brown/white wire should go into the # 10 plug on the main engine wiring harness. That is the inner most hole, It is inside the rest of the connection points.
Hope this helps.

Hi Bob,
Didn't have time to work on her today
the schematic is showing the brown/wht wire going to the gauge. the engine plug-in harness is fully intact with all wiring, I haven't even given it a 2nd look. With the others one thing that is messing me up is is the wire colors most don't match the standardized color coding. I'm thinking someone re-wired and used their own without labeling .

Re: The R?surrection of the SeaGem

Hey Bill,
I just went back through my manual and they are all basically the same. My manual doesn't show the one you have posted. If someone rewired yours running new wires may be the easiest way.
Good luck and let me know how it turns out.

Hey Bob,
Now you have me wondering, I got the one I have from the adults only section in Mercruiser here , manual#6 I wonder if the coding changed over the years. Well I am giving it one last look today then I am just going to run new and call it a day. I am going to try to get it buttoned up and get the engine in this weekend .
The only other thing I need to do then is swap a set of gears between sterndrives The new to me drive I have has 1.65 and I want to swap them for the 1.5 set off the old drive which the gears still look good in.

Re: The R?surrection of the SeaGem

Bill the brown wire is for the lightning rod and the blue wire goes to the nuclear disharge amplifier....jeez this stuff is childs play and you are messing it all up

LOL just kidding! hey you're doing a bang up job on that Gem....and heck I would hook up that old merc cathode doohicky cant hurt

 

[vegasphotoman]

Re: The R?surrection of the SeaGem

wow Bill your bilge is looking SANO

on the engine...Im sure you will be fine with the iron intake.... if and when you actually upgrade to a BRAVO........ you can easily replace the intake to the aluminum one and get that 396hp.....

Re: The R?surrection of the SeaGem

Hey Bob,
Well you were right, I traced the wire back from the gauge it was brown/wt right to the engine plug. I still have 2 wires I have no clue what they are for 1 is a 2pair black and brown the other is a single brown . I am thinking they go to one of the hydro pumps. I am going to try and figure it out tomorrow if I have time


Hey Vegas, Welcome back I'm trying man, I already have the lightning rod & nuclear disharge amplifier hooked up. I use the excess power to run my DeLorean Lol . Funny story I was driving beside one one day turned to my wife and said Its a shame what happened he had a real good idea ( meaning SS ) Colleen says "What a time machine" OMG I almost drove off the road

Hey Bill,
Don't say that I'm right to loud. No one will believe you.
Just glad I could help.
I believe that brown goes to the bilge pump.
Good luck

Hey Bob,

The bilge pump and blower are hooked up and working. The trim tab pump is not and the 2pair wire was just laying , someone had spliced it to a piece of SJ cord and the other end wasn't attached to anything. the wiring is a mess, they used regular blue barrel crimps all over the place. Needless to say all of it corroded apart to make matters worse they didn't stay with the same colors. I have blue spliced to green/ brown etc whatever they felt like to add wire. I have the dash pulled apart and tracing from the source. I soldered up a bunch yesterday and gave them a few coats of liquid rubber and heat shrink that I use on outdoor cooling towers & heat trace. I figure that would make a bulletproof connection & water tight seal.

Re: The R?surrection of the SeaGem

Small update,
Well its not even 4:00 here and I am burnt for today. Finished the wiring, the other brown and black wire well the black wire is to ground the brown wire goes to the bilge pump switch. The switch is a double pole double throw switch, the one side already goes to the bilge pump that's there maybe there at one time was 2 pumps one for a backup?

The single brown wire goes to the dash has a wire tag labeled "A" and well I found the corroded off end but no clue where the heck it goes can't find the other side of it . Think I am going to say the heck with the one wire and tape it off, all my gauges, switches etc... are working right down to the windshield wiper lol. So....... I should be installing the engine on Sat/Sun ........Maybe / Hopefully if wifey lets me :redface:

Edit- This is what they did for wiring, here is a small peice of SJ, notice the
connectors

One hot wire turns the pump on to test the pump mostly. The other hot wire ran through a float switch to the pump. Known at the automatic setting it turns the pump on when the water level reaches about 2 inches.

Just my 2 cents

You might be on to something, with auto/manual I looked at the wiring diagram for the pump it shows the brn/wt to manual and the brn to automatic. All the wires are hooked up at the pump from the PO but I bet the brn is hooked wrong especially being that the pump only works in manual. I will check that after my sons baseball game.

Re: The R?surrection of the SeaGem

"A" stands for autopilot. You just solder it to the steering wheel and the boat should drive itself!

Hope to get the single board bunks under her today, bill. I think you are right. The two together just couldn't flex enough. We shall see.

Small update, Yesterday My pal Charlie cam over and we got the engine out of my basement and put the heads on. Today I installed the intake and fuel pump, water pump and painted everything . Here is how she looks now

I also painted the accessory brackets, motor mounts etc... (not shown)

Now all I have to do is find the right dipstick tube for it an auto one won't fit it interferes with the exhaust manifold.
I posted in the Mercruiser section asking for help yesterday, and bumped it today, but so far to no avail .Thank God for you folk or I might be out here spinning in the breeze . The closest I found for a 70ish block with the dipstick on the drivers/port side was a 305 & 327 and their listed as obsolete.

At this rate I think I am just going to make my own by bending up some tubing and sweging it into an automotive dipstick tube end and give up on the Mercruiser section of the forum.

Re: The R?surrection of the SeaGem

Great looking engine Kenny...
I always liked the ford blue or chevy orange blocks..made finding them oil leaks easy..lol
Dont have any magic pills for your dipstick problem...
No wrecking yards around you that you could scavange a 327 stick off of?
Sad day when a 327 SB is hard to find..I had one in my 66 Chevelle
