I have a wm7 Super 10. I can't find service or exploded view docs with speed. Therefore I am uncertain of what to expect when I gut the motor.

Is there:
a detent to secure flywheel (crank nut) or does one use a strap wrench?

to remove lwr cowling does powerhead come off also? 3 studs per side under lwr cowling hold tiller bracket and 2 fasteners for fuel connector. is the power unit then free? is there a spline coupling between vertical drive shaft and crank at top or bottom> or what?

is water pump in vertical shaft housing or lower unit? it looks as if lower unit unbolts and slides out from vert shaft housing. Again, is there some splined coupling.

What is point gap at TDC? Plug Gap? What type of ignition wire do I buy to replace? Is there a fuel pump rebuild kit? Any merc point set drop in?

What SUPRISES should I be aware of before they happen???? rogerdavis1956@gmail.com
