1999 Evinrude 8HP 4 Stroke (E8R4EEM) One last dumb question?

[TaperSteve]

OK.... I say dumb question because before I started to break down my motor I forgot (or should I say didn't know) that I was supposed to pay attention to the direction the "cam pulley" and "crankshaft pulley" where lined up.

What I have noticed is that the "cam pulley" has the smallest little marking on the top of it on one of the teeth. When I turn the "cam pulley" it doesn't seem to line up with any noticable sequence with the four valves.

There aren't any noticable markings on the "crankshaft pulley" but what I did notice is when the "crankshaft key" is facing towards the cylinder case both pistons are compressed all the way also towards the cylinder case.

Which way should these two gears be lined up or what can I do to figure it out? Obviously these two gears run together via the drive belt and I've been told these two gears have to line up a certain way for the motor to run properly.

One major concern of mine is is it possible to damage the motor if I try and run it and these two gear aren't lined up properly? Otherwise I suppose I can try it one way and if its not running good or working at all I can re-adjust the way the gears line up and try again until the motor runs correctly.

Any help would greatly be appreciated!

Thank you!

Steve

Did you find a mark on the flywheel ?? You found the one on the camshaft pully.

OK, yes I can see the arrow on top of the flywheel and it lines up with the crankshaft key as seen in the first picture.

In the second picture it shows the small marking on top of the cam pulley.

Put the belt on the crankshaft and then put the flywheel on. Seeing the mark is on the inside of the flywheel, you may want to mark the outside of it. Then put the cam shaft pulley on. Get the two marks in alignment (across from each other} and install the belt. Put some blue loctite on the screw that holds the camshsft pulley and torque to 84-106 in pds. Make sure you get the belt timing correct as I don't know if this is a free wheeling mtr or not. If it's off you could damage the pistons or valves. I'm tired of typing LOL.

Steve, the only dumb question is the one you DON'T ask. You're v-e-r-y lucky you caught that before you reassembled and tried to start it!
