Looking for a Mercury thermostat housing off of a 1998-2000+ 454 or 502. The merc p/n that I am looking for is 861006A1.

Thanks,
Jon

i think this is off a 2000 or 2001

Thanks for the reply, but this is the style I am looking for. Usually the small barbs that run to the exhausts are push on not thread in like the picture.

If your looking for new, these stainless steel housing work well.

Will you please PM me your best price on these housings? Are they the Sierra 18-1989 housings?

Thanks,
Jon

The Merc part is too expensive - I'd go with the stainless ones!!

I have used those .....they work well ......m

I "think" the Merc part is stainless also. It might be one of those pieces where they were originally made in stainless but then switched to iron at some point?

Jon, I believe I have a Merc take off like the one that you need. Send me a PM if you still need it.
Thanks, Curtis @ Billet Marine
