A.A Thermostat Housing Sleeve Replacement For Mercury MerCruiser 23-806922

Good OEM alternative. Fits my 1990 Alpha 350 Mag Mercruiser. If youre changing the thermostat, you should change this part while you have the housing open. Dont forget the gasket kit too!

Came quickly and was as described.

Worked for my 2005 Centurion Enzo SV230 with a mercruiser 5.7L black scorpion. The old one was hard to get out and broke during removal. Im glad I spent the few extra bucks to have this one on hand while doing the repair.

Perfect fit for 2008 Tahoe Q4 with Mercury 3.0 engine.

Part fit perfectly on my 2002 Glastron with a 3.0l Mercruiser 4 cylinder engine. Opens at 160 degrees. Holds engine temp at about 155 consistently (Fresh water use).

Exactly like the OEM one I pulled out. So far everything is running great.

Perfect fit same a original!

Very good

Works good

Hesitant on this product at first, but it fits perfectly and has the notch to assist with install. Installed on merc 7.4l.
