This pump will fit most MerCruiser, OMC, and Volvo Penta 4cyl engines, 4.3L V6, 5.0L V8, and 5.7L V8 engines.
It will also fit some 7.4L models - please compare return line location. This will fit models with an o-ring on the steering hose (majority).
To determine simply pull your high pressure line and look to see if there is an o-ring at the end of it.
A replacement for this o-ring is also included.
The pump body can also be removed and reinstalled in your reservoir if you prefer - all the new o-rings can be transferred over and your reservoir used if needed.
