    Jumping in late on trying to noddle this issue that is perplexing and get the OP back on the water. To help with that below is a summary to date with some items that are perplexing (perhaps only to) me. Bought late last season all was good and ran WOT at 35+ MPH. Did a bunch of maintenance...

    Help with early 80s mercruiser 140hp

    Quick follow up: if you are planning on maintaining your engine / boat yourself I encourage you to get some basic hand tools and a dwell meter to properly set the points. For old school guys like me that means (at the time) an expense Craftsman Dwell Meter. Fortunately, these days they make a...

    Help with early 80s mercruiser 140hp

    As you are probably familiar with there are three basic ingredients needed for an engine to run: compression, spark and fuel. Many other items needed, like correct timing but those are the basics. Given the mechanic’s expression of good compression and that the engine starts but sputters out -...

    Mercruiser Setting Timing on 3.0L

    Hopefully it has been clear to you based on my posts that in addition to guidance I also try to instruct. Said differently it is in my nature to teach. Perhaps you have heard the expression: "Give a man a fish, you feed him for a day; teach a man to fish, you feed him for a lifetime" I know you...

    Mercruiser Setting Timing on 3.0L

    I will try to answer but not in the order asked. I will start off showing my age with a quote from the past but with an element of modern times. Here it is: I put your comment of “Also, as for the head. I took it to a machine shop today” into the latest AI ChatBot and asked for a translation...

    Dan, Congrats on getting this far, you should be proud! So now for some additional How Tos. 5.1 Flatness > already explained and need to compete. 5.2 Cracks > I will provide a brief explanation but I am suggesting jump to 5.3 first as if an issue with valve sealing and needs to go a machine...

    Mercruiser Setting Timing on 3.0L

    Quick reply as I must run: Bolt color does not matter. Follow Sept 5.1 of post no. 29 to check the straightness of any straight edge you buy. Try to buy one at least as long as the head. And while your initial measurement of 0.04mm is promising, you really need to follow all of the process for...

    1981 MerCruiser 120 tick/ squeak

    Thanks for the additional info. I am jumping to the assessment that this is like a member of the family with a lot of great memories. I envy you. As you may know oil in an engine provides more than just lubrication > it’s also a cooling agent. And unfortunately, when the oil is down that low...

    1981 MerCruiser 120 tick/ squeak

    Your ticking noise is more then likely a lifter as AD suggests. However, I suspect a deeper issue and that is the loss of the 2 qts of oil. Can you provide a history of how long you have owned the boat along with what maintenance you have done this season and when (like last season when...

    Congrats!!! I love the way you tagged the pushrods ;-) Regarding the head bolts > there are a lot of opinions out there and ultimately it comes down to ‘are they overstretched’ > a bolt stretches for the clamping force and if it is not ‘overstretched’ it will spring back and can be reused...

    My only objective was to raise your awareness I try to be careful in my posts, but I get surprised by Mr Gates sometimes… maybe I should try a different software :-) I too have kicked myself there and as much as it hurt, I do not forget the lessons.... I know it can be frustrating, but I am 100%...

    Mercruiser Setting Timing on 3.0L

    KD, Holy Cow Batman! Expensive lesson. Dan, More on what KD is talking about with respect to valve lash (aka valve adjustment). Your lifters that sit on top of the cam that the pushrod seats into are hydraulic (vs solid). Literally a little cylinder with a piston inside with a spring underneath...

    Mercruiser Setting Timing on 3.0L

    Awesome step by step > I am going to copy that and save it! Of note is that you may not need to take to machine shop > post those pics as suggested and then clean and then check for flatness. No issue if do, that is the safest route but is $$. The acetone will also work for checking for valve...

    2012 3.0L TKS runs great with muffs, but slow on lake...

    While good to keep watch on the temp, the impeller is probably cavitating like heck and thus may burn up / become less effective. Also, the temp rise on the risers and the downstream rubber connections, etc., will see a spike in temp long before the motor temp sensor. Recall the water flow is...

    2012 3.0L TKS runs great with muffs, but slow on lake...

    A note of caution: do not run your motor past a high idle when on the muffs. While a burp up to say 2000 is ok you run the risk of overheating your engine and/or ruining your impeller running it up to 4500.

    Lou, that is a great side by side picture. Makes my arms ache looking at the OEM. I now have the perfect suggestion for what the kids can get me for xmas! Better then tools (well almost :-) )

    Mercruiser Setting Timing on 3.0L

    Its looks good. This is great pre-planning. But prior to getting the torque wrenches get the torque specs for your engine to make sure they are in the right range. On the low end will be things like the valve cover and riser to the manifold. High end will be the cyl head. Ideally torque wrenches...
