You guys are always awesome. Thanks Rich!

Ok... here's where I'm at.

Got the engine mounting sorted properly (The double spun lock washers).
Tackled the rest of the wiring (Except the Tilt/Trim... that is soon and should be relatively easy)
Got the Tach working, Temp working, Volt meter working - verified I am charging.
I think fuel gauge is working, but I won't know till I put more gas in it... only a gallon in it.
Outdrive is on, with a new gasket kit.

Ran on the rabbit ears and all seemed well. It ran about as good as it did on the ground in the garage... just need an idle adjustment.

Water was flowing. Gears engaged forward and reverse. Temp was good. Oil Pressure was good. Volts good (14ish)

Shut her down. Checked oil. ....

Dun dun dun..... water in it.... all milky....
Now.. this thing has sat around a lot... and I know it was exposed to rain and got water in it just sitting......

SO - next up for tomorrow:

1) Change oil... run some seafoam and maybe some heat in with the oil? Get her flushed out... running with no water briefly.

2) Change oil again..... run it some, on the ears/water. Check for water in oil.

Leads me to my next line of questioning.....

Compression was good on all 4 cylinders. All 4 between 125-128

If I flush it out and she's still getting water in her.... is it still possibly the block? Water jacket?

Could also be the manifold... I know that... so I guess it would make sense to get a couple manifold gasket kits?

I have a spare manifold... so I could change gaskets - look for cracks - run it... if it's still wet, change em again and try the other manifold? and if it's still wet..... ummm..... find another motor and do this all over again? lol

I could use some fresh insight.... and emotional support,,, long day to end up with this... crossing my fingers that it's just water that collected in the engine while it sat outside for 2 years... and also that it didn't crack the block... dang...

Nooooooo

Compression is a bit low, should be 140-150 so that engine isn't going to have as much power. A bad head gasket will also let water into the block but I would be checking for cracks from freezing.

Shorty · « **Reply #23 on:** June 26, 2015, 09:35:14 PM »

The compression gauge I used was pretty janky, and the schrader on it was a little leaky too... so I wouldn't be surprised if it was reading a bit lower than it should..... but, I'm also not confident in this engine anymore.... so... there's that

So the Q now, is, should I bother with a head gasket and manifold gaskets.... or just wrap this project up and move it along.... hmmm.... I suppose it's worth popping her open, taking a peek, and maybe tossing gaskets in it....

This certainly isn't good. Check out this oil.

That isn't good! Sorry Shorty!

GO TEAM!

When testing it on the ground in the garage I never had it running for long. Probably 20-30 seconds at a crack....

My buddy made the point that it wouldn't really circulate everything in that time...
So, running it in the boat for an extended period could finally turn it all over and suck water.

This engine sat outside for a long time without the fuel pump on it, no carb on it, etc... so definitely could have gotten a bunch of water in it that way.

Drained the oil and left the plug out for a day and a half.... threw in fresh oil AND FILTER ... ran it on rabbit ears for about 45 minutes.... all good.
Checked oild throughout the run time. All good. Checked through filler into valve train. All good.

Let her sit a while to settle... checked oil level. oil clean. no water. Level good (no raised level from water getting in)

Went to start her again an she smoked the impeller in the outdrive... which I was waiting for lol... thing sat for a long time so I was sure it was gonna go (have a kit on the way monday)

So, we then ran her with the hose feeding right to the water inlet at the stat housing... ran her for another 45 minutes or hour.
ALL GOOOOOOOOOOOOOD

We also let her sit with the hose on running for another couple hours. Still no water in the engine.

Tadda.

Got shift and throttle all dialed in.

So, this week: Impeller. Tilt & Trim electrical connections, fill, bleed.
Then.... water test!

Almost there!

I'm a little uncertain still, but I threw a lot of water at it and none of it is in the oil.... so... uh.... crossing my fingers

Hello Ladies & Gents

Got the steering hooked up. Got the Tilt & Trim wired up, filled, bled, and working great.

Now to my final hurdle before water testing tomorrow.

My control box keeps disengaging from the shift cable.
The inner cam and outer shift 'cam' assemblies fall out of sync and when it 'slips out' it won't realign to neutral.

Anyone have any ideas on why this would be happening? Is there an adjustment situation that could cause this?

I do have another control box, with a bad throttle cable... so I think tonight I might swap the box out and see if that takes care of it - like, maybe the cams are worn in the one that's in it now.... but I'm not sure why this is happening.... so, any pointers or ideas would be great!

Thanks guys!

I've only had a Morse control for my jet apart and they are different but someone previously had it assembled wrong and I did replace a couple of bolts. This stuff is old and wears out. Maybe the cams or whatever holds them on?

Shorty · « **Reply #28 on:** July 01, 2015, 11:34:56 PM »

I tend to move sorta quick on stuff sometimes.

After I posted I tore into it... stuff was pretty well worn in the one... so I swapped a couple of the 'cam' components... the whole assembly the handle turns, and the lever the shift cable attaches to ... wish I knew the correct terminology for these parts so I could sound smart... but anyway, they were worn bad and I swapped em with good ones from another unit... all seems good so far.

Tomorrow, Ian (EMS) is coming out and we are gonna take this beast out for a water test, and spend some time on Goldie (his CV16SS)

I'm stoked. Crossing my fingers on this motor

Uh oh, there's a second Goldie in our midst?

Shorty · « **Reply #30 on:** July 02, 2015, 06:04:32 PM »

I may have misspoken on the name. lol

Successful lake test though. Couple very minor things to tidy up next week.

Lookin good so far!

Shorty · « **Reply #31 on:** July 02, 2015, 06:55:01 PM »

A shot from the cruise.

Surprised how well she performed. Jumped right up on plane with no effort at all. Didn't open her up. Only about half throttle out cruisin. Baby steps. Taking it easy.

Jason · « **Reply #32 on:** July 03, 2015, 10:15:20 AM »

Awesome! Sure is nice to see that boat back on the water. Nice work Shorty!

Rich_V174SS · « **Reply #33 on:** July 04, 2015, 09:03:57 AM »

Very cool!

Plugcheck · « **Reply #34 on:** July 04, 2015, 10:38:08 AM »

Easy smeezy, beat her like a rented mule! Just kidding, looks like you did a great job getting her back on the water. Hope she treats you well the rest of the season, enjoy!

Shorty · « **Reply #35 on:** July 09, 2015, 09:53:56 PM »

She sucked water. Runs out like an absolute champ, but, sucked water so I shut her down...

Had her at 38MPH GPS at 4500 RPM... not sure what redline is on these mercuiser 140's (3.0) ... I forget. I'll look it up... could have gotten more R's but I was nervous about her still and hadn't checked for water yet....

so... tomorrow the head comes off (Gaskets are in)

Rich_V174SS · « **Reply #36 on:** July 09, 2015, 10:28:07 PM »

That engine should be turning 4500 at 45 mph but 38 aint too bad. What prop are you running on it? I had my old Mercruiser 120 running 40 mph at 4600 rpm in the V174 using a Quicksilver stainless 21p prop, about 36 mph with an aluminum Black Max 21p prop at the same rpm.

Shorty · « **Reply #37 on:** July 09, 2015, 10:31:43 PM »

Haven't even looked at the prop to see what it is yet. It's not enough prop then, cause I coulda ran her up quite a bit more yet (Probably coulda got another 1000 out of her). bet I coulda popped the motor if I wanted to...... I'll dig through the stack and compare.

Thanks for the info

Might be hard to see but check for cracks in the head from combustion chamber to water jacket. The guy rebuilding my 140 told me he's seen a few crack....Not sure about mine yet. I would also check the flatness of the head in case it warped at some point.

Those are decent numbers though!!

Ditto on the cracks in the combustion chamber. the 140 i rebuilt had that issue too. BTW I have a good head from the 120 if somebody needs one.
