2020 Yamaha F150 outboard impeller replacement

Time for annual/100 hour impeller inspect and replace on the main outboard that I’m doing prematurely because I power loaded the boat and it ran out of water approx 30 seconds, noted it took just over 4 seconds for coolant water to discharge and it was low flow when it typically discharges in less than a second, has hard stream. Better safe than sorry.

Wow, what a perfect video. Thanks for this! In a day and age where everyone ruins videos with useless rants and nonsense, someone's still doing it proper!

Thank you, Thanks for watching.

Good video. About to do mine, but why remove the propeller?

[@ryanvtec3885]

how did the owner blow the pump soo fast just cruising on dry land?

[@kwikrench]

You could sorta say that. Mainly the engine so quiet forgot it was running when pulling out of water it ran 30-40 sec out of water, noticed next time on the water the coolant pressure dropped from 16 to 10 and the pee stream just spitting at idle. Temp didn’t get hot but changed impeller and restored pressure. Dry land cruising is no joke. It happens fast. Thanks for commenting

Did you have it in gear

[@kwikrench]

No. Neutral. Thanks for asking.

Unfortunately as a marine mechanic myself, there's a few things that you didn't do properly. 1) you didn't replace the woodruff key, why not? Did you re-use the o-rings? Including the one on the impeller housing? It's actually ok to use a bit more grease in the impeller cup. It doesn't hurt anything. I don't understand why you put grease on the o-ring for the impeller housing? Unnecessary.

Dry land cruising with only 23 hours on new outboard. It was out of the water for 30 sec, didn’t get hot so ordered only the impeller and housing kit, the grease was tacky enough to hold the o’ring seal in place for Assembly. So didn’t need the whole 100 hr parts. I went to flush engine in freshwater and noticed the tell tale took forever and just dribbled, coolant pressure was 1/2 the original especially at idle. Now the tell tale is instant after startup and good stream coming out, I’ve put another 38 hrs on since then. Thanks for watching and commenting.

What tool to remove the anode?

[@kwikrench]

It’s threaded. There is a rubber plug above. Pry it out and it will expose the bolt.

I wish I could read your torque wrench

[@kwikrench]

If lower unit torque is what you’re lookin for it’s 34 ft lbs on 2020 Yamaha F150. Thanks for commenting.
