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

Perfect fit for 2008 Tahoe Q4 with Mercury 3.0 engine.

All good

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!

Fit perfect

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

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

Perfect fit

Very good

Perfect fit same a original!

Works good
