You need Merc manual 6......well i went out yesterday and checked the outdrive out, my old boat i had water that came out the exhaust (prop) warm water, but the new one has two holes one on each side of the gimbel, the warm water comes out there, if the water impeller is bad would warm water still be coming out those holes?
Yes, water pressure from the hose will still push some water through.......
Im more than likely going to replace the impeller anyways, but just curious on how the impeller works. is it hard to replace the impeller, and any important things i need to know upon doing this? Thanks for your help guys
sure, observe the temp gage, or, let it overheat. then ya'll know.....and ya'll still end up taking it apart to repair it. + ya'll get to go find as many pieces of the impeller that ya can find hopeing chunks of it don't find their way into the cooling passages inside the engine, where ya can't go get them, let alone the other rubber parts that will get smoldered too....
when on the bench, it's easier to R&R the impeller. however ya can take just the lower off too. but it's much harder to put it back, but not impossible. if ya remove the drive like hm says, ya can also do other pm that yer supposed to do yearly too. like grease the coupler splines, lub the ujoint, inspect the bellows, check alignment.......
