    1981 MerCruiser 120 tick/ squeak

    i just looked into that rocker more. The push rod for that one is bent. Coulld this be the cause of the issue or a result from bad lifter?

    1981 MerCruiser 120 tick/ squeak

    Hi all. The season is here and finally got her out of storage. 2 cranks and fired right up. Cold compression readings prior to start cylinders 1-4: 150, 125, 120, 140. Compression readings 1-4 after engine is warm: 140, 120, 125, 125. Shakes at idle but doesnt seem to be missfiring. Adjusted...

    1981 MerCruiser 120 tick/ squeak

    Okay I will do this as my first steps. When the tick first started I removed the valve cover on the lake and didn't do a very good inspection but tried to do a running adjustment (loosen until it starts to clatter then slowly tighten till clatter goes away, then 3/4 turn more) but it was hard to...

    1981 MerCruiser 120 tick/ squeak

    Do you think I could buy new lifters and change them with the engine still in the boat as a last ditch effort for next season?? I really dont have the time or money right now for a rebuild unfortunately. Put her away in storage this past weekend it might be a long one if i cant figure something out.

    1981 MerCruiser 120 tick/ squeak

    I was able to get a video of it running. Seems to be getting worse. What do you guys think it is? The video with the engine cover off is right after start up. The video with the engine cover on is on the way in after running it for a while.

    1981 MerCruiser 120 tick/ squeak

    Loss of two quarts is my fault there was an oil leak I let go on longer than I should have coming from the valve cover gasket. The two quarts was lost slowly as the oil leaked out after about 8 rides. The oil leak has since been fixed but I neglected to check the oil being in a rush when i fixed...

    The temp gauge still reads a nice 140F when at full operating temp. Can the water pump be bad and still run normal temp?

    1981 MerCruiser 120 tick/ squeak

    Hello all, Im back again with more 120 mercruiser problem solving. About a month ago I was on the lake cruising around 4000 RPM when I heard a change in exaust note. The engine exaust noise seemed to increase so I stopped the boat wondering if a hole had developed in the exaust manifold. When I...

    1981 Rinker 17 foot I/O open bow loose steering

    The steering on my 1981 17 foot open bow has been getting worse and worse over the last few years. The steering wheel has significant slop back and forth and the play seems to be coming from inside what I believe to be the rack and pinion under the wheel. I was wondering if there was any way to...

    Hello all, Been hitting it hard this summer trying to get out as much as i can but ran into some trouble the other day. Was cruising at about 3800RPM when all of the sudden the engine started to backfire terribly. Came to a stop and started to poke around when i removed the vale cover i noticed...

    1981 120 Mercruiser idles rough when hot

    Success at last. When i felt how hot the coil was i ran to the autoparts to get a new "stock" coil, reconnected the ballast resistor, and it ran good for over 20 minuets! Like they say shes fixed for now we will see what happens when i put it in the water this weekend. Thanks for all the help
