replacing water impeller

[coreynov902]

I have a 1999 175 EFI. My question is, how difficult is it to replace the impeller? I'm not too mechanically inclined, but my father-in-law is a mechanic, and he's done quite a bit of stuff with his 115 4-stroke. What kind of cost difference would I be looking at if I do it vs. having it done by an authorized Mercury mechanic? Are there instructions online for how to do it? Lastly, just to show my ignorance with motors, is there a difference between a water pump and a water impeller with regards to outboards? Thanks!

Pretty straight forward, only hard the first time. Usually changed annually, if its been longer, I suggest whole kit and not just impeller.

I bieve there is a walk-thru under sherms tips on the left side bar. Has pics...etc. if you get the kit, dont freak out when you have extra gaskets/hardware, just match what you have and take pics each step to get gaskets in correct orientation.

If your going to do your own maint, please get don to order you a manual. Must easier, pics, step by step...etc

Impeller is the part that spins and pumps inside the pump, whole pump includes gaskets, plates, and housing. Price difference is minimal, $20+ for impeller and $40ish for whole kit. After taking the time to remove the lower unit, it only makes sense to replace the whole pump. Parts to replace will cost less than $50-$60, paying mechanic is usually $150-$250, can't remember exactly what I paid last time, been awhile.

Thanks for the info guys. I'm new to the board, so I don't know who Don is to ask him about a manual.

Also, where do you guys recommend getting the water pump kit from? Thanks
