Welcome,
Under the cowl is a tag with model and serial #s
You can post them or go to Mastertechmarine and figure out what you have.
That motor is ALL Chrysler and just has a "fancy" name.
The Tracker used some Forces and eventually Mercury.
The "hard" parts can still be found, service is another thing??
About the only places that will work on them are the guy's with shade trees.
Not many dealers will touch them.
It's going on 35 or 40 years old so be careful and if it comes from a state with salt water?? Think about it?
