temp. for 1992 Mariner 150 Magnum II

[Blue197320]

they are 2 different things. the poppet valve goes on the bottom of the block on the starboard side. its about in the location where your harness connects to the motor. should be less than 15 bucks to buy a new one from boat center. the stats are a few bucks each from boat center. its kind of a pain to do the poppet on your motor because of the lower cowlings. i think you have the same thing as i do. it might be easier to split them at the bottom and get to it.
