    Perfect Fit
    by Wade from Ukiah, California on September 11, 2012
    Fast shipping and fit my '86 OMC 5.7 perfectly. Only thing that I wondered about was the extra parts. I only needed 3 of the 6 parts (thermostat, o-ring, and the round gasket with the two holes). I figure it must fit multiple applications.

    This is exactly what was described and exactly what I needed. It was easy to install and works perfectly. I couldn't be happier.

    Will this fit a 1988 OMC 4.3L?
    No it will not. The thermostat does fit which is part number 18-3554. 18-0398-9 is the thermostat housing gasket.
