Your best bet would be to go to a dealer and see if they will at least let
you borrow the service manual for that motor it has in it how to line up the
pulleys when you put the belt back on.
Or you could have them order you a service manual if they won't let you
borrow it.
good luck Scott

Guys,

I got my Merc 1250 running fine. Then I decided to change the timing
belt which is very loose. While doing this the belt slipped and I
lost the timing.

According to online stuff for smilar motors the timing has to be set
by making the arrow on the distrubutor pully point to the line on the
flywheel.

When I did that the motor idles very high (3000 rpm).

There is a whole bunch of marks on flywheel and pulleys but i dont
know how they have to be ligned up.

Does anybody know? (this is a 1969 I6 motor, Thunferbolt ignition)

Any help appreciated (the dealer wont touch this motor
