Re: how do you ID an engine???????
Chrysler went bankrupt in 1983-4, was sold to US Marine.
Brunswick (Mercury's parent company) bought them in late 1989 and started producing their versions of them in 1990.
So you have a US Marine Force engine.
Mercury is handling all parts.
Contact any Merc dealer for parts.
A good online dealer is Crowley Marine, or Dougrussell.com
Most consumable maintenance parts are available here on iboats.

If you find a model number, it will look like
857F9C
In this case, 85 is the hp
9 means 1989
C means production version C
If you talk to someone about parts without a model number, they will give you a blank stare.
You have BLUE CD module ignition.
You have the old style 2 stage fuel pump.
Hope this helps.
