wiring slave solenoid

[jhande]

Letting the oil sit is fine. We used to use Marvel Mystery Oil and let it sit a few days.

I'm assuming the motor is an inboard?
If it is, try getting a socket on the crank shaft pulley bolt. Using a 1/2" breaker bar see if you can turn the motor over clockwise. A full 360 degree rotation is what to shoot for. If you can't turn it at all only hope is to keep soaking the cylinders.

If an outboard, try turning the flywheel.

If you can't turn it by hand the starter won't do it. Keep soaking the cylinders with something that helps eat rust and keep trying to turn bu hand. The motor might just end up being seized and needing a rebuild.

If the outdrive has not been removed, then do remove it.

Turning the motor using the crank bolt is a way of snapping off the bolt

ok ill do that when i'm done decided to go the hard way and pull everything off down to the heads good thing to because on off chance it turned i probably would of messed things up worse the the block isn't crack have got the heads out yet but they aint bent around the heads just got to check the legs if alls good i'll just clean out the areas and give it another go

Nobodies suggesting jumping on it.
Just a normal amount of pressure. I've done close to hundreds and never snapped a crank bolt.

its a inboard 260 mercruiser v8 and its locked tight i may have to hammer out the pistol heads and sand blast the block any ideas? please tell me i'm not wrong and i can treat it like a car motor?

For the most part yes, treat the block as a car motor. But sandblasting the block isn't the correct way of fixing it especially long term. Have you ever rebuilt a car motor?

 

[shannonbrimer69]

yes but never had rust issues like that what should i do just soak the block?

 

[jhande]

I'd start off tearing the motor totally apart, marking where each piston goes and all other parts so you can reinstall in the same place. Then you can inspect everything for how much rust and sludge is inside. Personally I would have the block hot tanked to make sure all the insides are clean and like new. Regarding the rusty cylinder walls you might get away with having it honed or worse case bored. You'll need new rings as they will be rusted up. Everything depends on how bad it's rusted. If it has noticeable pit marks that another issue.

I wouldn't want to take short cuts with a motor, especially one in a boat. Should something go wrong you could be stuck floating.

You said using a 1/2 breaker bar, that is enough to snap the bolt if its stuck. A 3/8 short ratchet would be ok. Best to use the belt to turn it with plugs out

Do agree, if your going to rebuild, take it all apart and have the machine shop tank it. Depends on how much your going to do, but cost it out before starting. Might be cheaper to buy a long block

got the final pistol out inspected that and the arms that dont look morphed or rusted the rings look fine too its the top parts on the cylinder walls that are rusted is there i cheaper way to get rid of the rust everything but rust on 3 cylinders the top parts of cylinders are rusted i guess i'm asking if the a cheap way i can do i myself without have to take it to a shop also thats no cracks in the block its all looks good except the rust

p.s never realized how stupid i sound when i'm exhausted lol

Get a cylinder hone and attach it to a drill. PB Blaster and have at it. Cheapest way I can think of.

Like I said, I've never snapped a bolt using the 1/2" breaker bar. I just don't reef on it.

 

[alldodge]

Look close at the top of each cylinders and see if there is a ridge. If there is it will need to be removed or better bored. If no ridge hone the cylinders or at least use sand paper on the rusty cylinders

I hope you marked each piston as to the bearing cap and piston or are keeping them as sets. You don't want to mix the cap of one to another. Same goes for main bearing caps

 

[shannonbrimer69]

i did i forgot to look for firing order but i markers the with whiteout as to what piston got the what cylinder like 1-1 2-2 3-3 4-4 so on it should work

ok got all my wiring redone except the black wire from the diagram i have i can't tell some insight from someone who know more about wiring would be great i think it grounds between the mounting bracket and the slave solenoid but not sure. also is it possible that if the black ground isn't mounted there that it can cause my slave solenoid to just click and not turn over the engine?

I've had like this with a boat before. Check for a voltage drop across your starter. IF there is no voltage drop then try turning the engine over and see if you get continuity across the solenoid. If it reads O/L the replace the solenoid and it should be fine.
Side note: I saw you mentioned a solenoid looking thing on the starter. That's most likely a start up capacitor for the start motor.

sorry for the late reply wanted to make sure this solution worked a friend of mine told me to do one part gun oil 3 parts wd40 penetrate i do it and the motor is free i cleaned it put it back together and now its turning over thank you all so much for lending me a helping hand and giving me some knowledge of stuff i didn't know about.
