@@natanieljames1026 thanks so much for the nice comment

Thanks so much for complement. Super glad I could help. That's my goal. Don't forget to subscribe 😁 I have lots of boat content

The Volvo Penta is the same block, with some different bolt ons

Thanks so much for the compliment! I've been working really hard, really giving KZfaq a shot. It's pretty common for these engines do blow the head gasket in that spot. Being that you don't know the full history of the boat I'm willing to get it overheated at one time and started to hurt that gasket. How low was the compression? If it's below 80 it could be causing your acceleration issue.

@@daleofalltrades Confirmed today with a separate compression tester the #2, #3 cylinders are at 65-70, while the other two are at 130. The prior owner even told me the only time the boat left him stranded was when a thermostat went out, so I think we have the culprit. I plan to begin the teardown tomorrow.

Yeah definitely not a bad idea. Order the parts online now. Took about a week to get my parts. Ordered mostly from Amazon. I bet when you get the head off you'll see some signs of stress on the gasket. Good luck. It's not too bad. While your in there check your exhaust flapper. They can get wore out over the years... Mine were gone.

@@daleofalltrades Thanks for the flapper tip, I will definitely take a peek!

@@daleofalltrades Confirmed! I had the exact same failure as you between #2, 3 cylinders. I have to clean it up and hope it's within spec, but I've already contacted a few area machine shops that have about a 2 week lead time.

Yea well unfortunately mine was cracked prior to my ownership. At least I'm not to blame.

My Four Winns engine cover splits open from the middle. Didn't think anything of it when I bought it, but boy what a dumb design, the engine gets soaked. Trying to come up with a panel I can put above the motor to keep it dry.

Thanks, it's been a fun adventure!

You got it!

Thanks 👍

Thanks. Good suggestion I'll try to touch on that in the future

Thank you! Sorry for your misfortune. Water in the cylinder while an engine is running is never a good thing. Take special care when inspecting the valves and push rods. If hydro lock occurred it cand bend things in there. Also while your in there check the exhaust flapper. I would figure out how water got in there. Thanks for watching. Best of luck!

I have a lot of history with automotive engines but this is my first marine engine, thanks for the tip on the exhaust flapper…there wasn’t one, ha! Found the metal rod it used to be on but I assume the rest fell apart and went out the exhaust, Hopefully it ends up being that simple.

Mine was the same. If it worried take the prop off and make sure the exhaust passage is clear. I had a metal piece of the flapper stuck sideway in mine. Worth a check for piece of mind. I'm in the same boat as you (pun intended) I'm learning as I go.

I did off camera, probably should have mentioned that in the video My bad.

I used this kit for the manifold (keep in mind there are 3 different head styles, this is the more common however.) www.amazon.com/dp/B0001CLFHY/ref=cm_sw_r_cp_apa_glt_fabc_8QKGZBSB3XY0CXFVBKD9?_encoding=UTF8&psc=1

And I used this head gasket kit (this should work no problem on any 3.0 mercruiser.) www.amazon.com/dp/B000CMGSDE/ref=cm_sw_r_cp_apa_glt_fabc_HT57FDD9MPP21MT7JZ5H?_encoding=UTF8&psc=1

Thanks for the compliment, glad I could help.

@@danlee1904 perhaps. Sounds odd

I had my wife tap the key and used the starter. Otherwise there is a special tool you need and you have to remove the front motor mount

Thank you.

@@daleofalltrades I used a remote starter button and it went much smoother than I was anticipating. I have a slight valve cover leak now though that I can't seem to remedy. I'm torquing to 40 inch pounds. Is that what you are going with? I hear people saying it feels like too much and can't help but think they are going 40 foot pounds. I'd like to know what you did and are you using any sealant or just straight cork gasket? Thanks a ton!

@@vdubluv222 I re used the rubber/silicone gasket that was on it. No leaks and they tightened snug. No torque spec used on my end.

@@daleofalltrades thanks again

So did I. I have a follow up video doing all this over again.

Only way to check valve lash is to loosen all of the back up and start over. Did you move the distributor around? Sounds like it got out of timing. Or the plug wires are installed on the wrong order

I did have a tad milky oil. It can cause damage however I believe it was caught soon enough as it's been a year now with no further issues

@@daleofalltrades Thanks.

@@donens9310 side note I did just recently purchase a used stripped block for a rebuild in the future just in case. My block is also cracked (prior to my ownership)

At 2:10 I cleaned the surfaces and at 2:19 I had put the head gasket on off camera but you can see it sitting on the block. Just didn't record placing it on. It's pretty straightforward, can't do it wrong. Make sure and check out my updated video that touches on some commeon questions I've gotten and more tips on replacement as I had some more issues a few months later. Lots of good info in this video. kzfaq.info/get/bejne/ppuhZsl2p763gWw.html thanks for watching!

Thanks. I didn't do a full year down so I didn't clean the pistons, nor was there enough water in my oil to matter. I used acetone to clean both mating surfaces. It's actually funny you should mention all this as I will have an update video coming out on mine. My gasket blew again. But the block isn't worth rebuilding cuz it has multiple cracks that have been repaired. So I do a Band-Aid fix in the video.

Well if a lifter "tappet" is broken then that is why your valves are out of adjustment... You'll need to replace the bad/broken lifter's or replace all the lifter's. I'd replace the rocker as and push rods also. Lifter's can fail. Although it's not super common it does happen

How did you get on 2 years later

Still running great

I should really do an update video

You have to remove it or use the starter and bump the key. But you can't do that once it's tore apart. Or you can put it all together and adjust the lifters the way I did at the end of the video

Once you loosen a rocker arm you have to adjust them regardless one re assembled. Also check out my follow up video here kzfaq.info/get/bejne/ppuhZsl2p763gWw.html

Yes, it's a pulling prop, you lose a little top speed but gain how quickly it plains out. It's a quick silver highfive

I used an unorthodox method which is why I didn't show it on camera. That being said I can't actually remember how I turned it. This was 2 years ago now. Honestly it's easiest to adjust the valves snug and then doing the rest buy ear like I did at the end of the video

You want the front cylinder (cyl 1) all the way to the top with both the valve closed. That is the compression stroke.

Hope that helps

@@daleofalltrades yes it does. Thanks! Your videos are awesome. I am doing the exact same thing Tuesday to mine. Head gasket, water pump, and all impeller and lower unit water hoses. Got a big overheating issue. I didn’t cook the head gasket, but it seems easy enough to change as long as I’m doing all of that to it. Thoughts?

@@daleofalltrades I should add, I bought the boat after it sat dry for 15 years. All the seals and stuff got to be rough by now. I have a whole gasket set to replace… worth the trouble?

Worth the trouble maybe. Worth the piece of mind definitely!

I don't quite understand your question, but here is part 1 kzfaq.info/get/bejne/esBppcaklqvNXYk.html

Been a bit since I did it..... If I remember correctly I used a pry bar on the webbing of the pulley. I'm a tag figgy how I pulled it of it's been almost 2 years now.

Yea it was a mistake on my part. But at the end I ended up adjusting with valve cover off and engine running. (The way I'm used to doing it)

However excellent video

All of them

@@daleofalltrades thank you!

Also, do I have to move each cylinder to TDC before doing it or just the first cylinder, leave it there and tighten?

If u want my honest opinion just get them snug all on tdc (top dead center) and then run the engine and adjust like I do at the end of the video. That will give you the best results.

Yes or a crack in the head or block

@@daleofalltrades thanks for the reply! So I did some more sleuthing today. Oil on dipstick looks new, no sigh of water there. I pulled the block water drain plugs and that water was clear. I drained the driveline oil and it looked good (no water as well). Is it possible that it hadn’t been run in so long there was a ton of carbon and what not to be blown out and that’s what made the exhaust water so black and smelly? I didn’t let it run long after I discovered that for fear of not knowing what it was. I’m planning on draining and changing the engine oil as well as driveline oil to see for sure. Gonna check compression and the plugs. Also gonna change the water impeller, no telling if that has ever been done. One more question, I didn’t hook up water to the driveline intake until after I got it to kick over/start. I never let it run for more that just 15-20 seconds. Could that have disintegrated the impeller and caused the black? It had been sitting for at least 2 years, maybe more, so I could see that being highly likely. I didn’t know about some of these things to do on a boat that hasn’t been running for a while till now (my first boat!), was just treating it like getting and old beater car running.

@@dkhallal if the boat has been sitting a long time the water will look pretty nasty Coming out of the exhaust

I believe so. But I can't be 100 percent sure. A simple Google search for you specific engine should verify. The head gasket is definitely going to be the same as the block really never changed on the top side

Pretty sure it's the same block. Can't be fore sure but I'm sure it's close

Any fine grit sandpaper will do

kzfaq.info/get/bejne/ppuhZsl2p763gWw.html Addressed in this video

It's also not 2/4 it's 1/2.... Keen eye. Yes I'm aware. Wich is why I had clatter on 1st start. Little mistake.

@@daleofalltrades 2/4 = 1/2 😂

Just being a smart A$$. All good fun.
