my mercury engine started knocking, with about 80 hours on it. and I don't have a lot of cash to have the shop rebuild it. so I had to fix it myself. this was my first engine, to ever rebuild. I took it to the lake, ran around for about an hour. it ran great. I thought some of you guys, may be in the spot I was in. if so and you want to try it yourself, here are some tips that may help.
don't be afraid, it really isn't that hard. it took me three days to rebuild mine, but I read and double checked everything I did. if I was doing it again, it would be a weekend job. just think of it as reading a roadmap, and going someplace you have never been.
if you know what the parts are that make up a engine, like the block, the head, the carbs, the crank, pistons, rods, rings and bearings. if you know what these parts are, you will have no problem rebuilding a 2 stroke motor.
first thing to do, buy you a repair manual, read the part on rebuilding your engine, using the manual. tear the motor apart, use different colored tape, and tape any wires you unplug. with matching tape colors.
and use plastic cups, and write on them the kind of bolts that you put in each cup. like head bolts, crankcase bolts, rod bearing bolts and so on.
when you start putting it back together, the marking wires and putting different bolts in the cups will make it easy.and remember to mark your rod caps and rods. each cap and rod has to stay together. they are mates.
when you get it tore apart, the manual will have pictures of different parts. that have gone bad, and what they would look like. to help you find your problem.
order yourself a repair kit, { Iboat has kits } mine was 555.00 and it has everything you will need.
just go slow read and double check everything as you put it back together, and you will do fine.
I was reluctant, to try mine. and after I did it. it was easy. saved myself enough money to fish on a couple of years.
ps...my motor went bad, because of piston not getting enough oil. after I got it rebuilt, I unpluged the auto oiler, and mixed the oil in the gas tank myself. now if the pistons get gas, they will get oil.
I hope this helps someone.
