Full StarEmpty StarEmpty StarEmpty StarEmpty StarMissing parts
by James from Cascade, Colorado on May 17, 2015
This product did not come with the appropriate Gasket, which it should. Which made it junk to me. Wrote it off as a waste of money, because It would just cost more to me to send it back.

by Joshua from Camden, New York on June 23, 2013
This thermostat failed to open and my engine overheated. I have never been disappointed with Sierra products until now. Now my engine is running poorly and I'm hoping the head gasket let loose before the rings got cooked. 1973 Evinrude 25HP

Full StarEmpty StarEmpty StarEmpty StarEmpty StarWrong Thermostat Kit for Mercury Outboard
by Anthony from Key Largo, Florida on August 26, 2011
According to the iboat website, this thermostat kit is compatible with my 1993 Mercury 150HP outboard...it isn't! Save yourself the aggravation of water spraying out between the thermostat housing and the valve covers and being told that the parts are not refundable unless they are defective. I'm certain that these thermostat kits do work in some engines, just not in the outboard iboat's website references. Too bad this review does not allow criticism of iboat's customer service... I'm still waiting to see if I'll receive a refund due to their error!
