Hello;
I just got a 24-ft 'toon with this merc on the back. It appears to have power, but I noticed that when running, there is a rattling sound (and changes intensity at times), it?s not when moving slowly, or if I reeve the engine in neutral. If it were a 4-stroke, I would say it sounds like valves. Could the shaft / lower unit gears be loose/worn and wobbling? (or would that prevent the thing from running at all).
It appears to run OK, other then this rattling sound. (I do recall the Mercs of that time were loud- we had one when I was a kid ? late 70?s) I looked inside, nothing loose, but noticed that the insulation on the cowl is missing. When you put you hand on the cowl when running, you can feel the rattle vibrations.
If there were issues with the lower unit, would I experience other problems? (Like I say, it has power, and moves the ?toon at a good clip- 20MPH 5000RPM WOT). Don?t know the prop pitch. And its missing that fin that sticks down behind the prop. It?s a brass prop I think.
Could it be the insulation is missing, and it?s the cowl that is rattling?
I also go through 5 gal of gas traveling 17Miles. And that?s at ? throttle! ? I?m getting a bigger tank!
