Question edited for a lot more clarity and correct spelling of the maker.

When checking the compression on an outboard motor... you aren't looking for the final number as much as the percentages of variation. There are so many things that can vary the compression numbers, like throttle position, air temperature, and even the tilt of the motor on a four stroke, that the manufacturers don't put the numbers out. What you are looking for is less than 10% variation between all cylinders. So if 3 cylinders are giving you 120 psi and the forth cylinder is giving you 105 psi, that hole has a problem. In the old 2 stroke days what we would find is people were using air cooled 2 stoke oil, which has a much higher burn temperature, and fouling the piston rings with tar.

I don't think mercury has changed their engines much in the past few decades with the exception of the newer high tech & 4-strokes. You can probably get the procedure from a shop manual that covers their 2-stroke 65hp from the 90's or later. The easy part is that with it being a 2-stroke there will only be 1 top dead center as opposed to a 4-stoke which appears to have 2 until you figure out if the rotor is pointed 180 degrees the wrong way. The only other thing you need to know is which cylinder is #1. Bring that cylinder all the way up. The markings will be on the fly wheel and the engine block. What's left... a few degree before or after. You should be able to get it going with some trial & error & maybe fine tune it by ear. I did this with a Mercruiser & found out I had it perfect 5 years later when I got the shop manual. Good luck.

Do you mean it clicks and starter not turning ? if yes then the starter solinoid wires are loose or it needs replacing ! more info needed !

Quiksilver marine dealers !

check the coil maybe it needs replaced

I have a problem with my 2 stroke 20hp mercury 1989,when I run 10-90% throttle it's works fine but when in 100% its only runs in 90% and doesn't sound normal like it's not burning right.
