Every other season. They come out looking pretty good.

 

[Blubyu]

Every year, weather it needs it or not. Cheap part that can ruin a whole weekend.

Every year.

 

[BHC Vic]

Yearly even when I only put 10 hours on the boat

 

[Rondog4405]

Yearly.. Why not.. Already at the shop might as well get err done.

 

[4Waters]

Every 100hrs or every other year

 

[cofooter]

I gotta do my outboard just to be cautious but the pisser has not changed in years, if you don't suck up sand they last a long time.....

 

[Allwaysbroken]

Every year, including changing the oil on the cam the drives the fuel pump.

 

[dribble]

The last time I went from 2011 with a new Hardin Marine stainless housing to 2016 and it came out looking great. I'm doing it this year before the season starts.

With sea pump mounted fuel pump it is a must. Oil is always fuel diluted.

 

[Riley1]

Every other. 496HO. This will be the start of my second season on this one. This will also only be my 4th season with the boat. So not too much history with this method.

 

[redone76]

Every other year

Every other year. Never had a problem.

 

[Echo Lodge]

Every 18 months on both of my rollbar boats. I carry spares and can change on the water if I have to. On my Nautiques I get a slight warning as the boat will run 10 degrees hotter when the impeller gets tired.

 

[milkmoney]

Every year with service . Like said, it us a cheap insurance policy compared to what the damages it can do ....[emoji41][emoji202]

[DWC]

Yearly, before first trip of the year

 

[PlanB]

Every other year on the Verado.

 

[farmo83]

Every other year. I carry a complete rebuilt kit and spare at all times though.

Unless yours is on a Hamilton 212! Lol

 

[oldschool]

Beginning of every season. Cam driven Magnaflow pump.

 

[Flying_Lavey]

Every other year. The 2.4L Mercs tend to go through them faster than their larger brothers.

I forgot to add that I have Vessel View Mobile and can see a whole lot of details on both of my engines, water pressure included. I usually check it at the beginning of each day. As long as there is about 32PSI of water pressure at idle, good to go. If that number starts to drop, it's impeller time.

 

[mash on it]

Only when it breaks, by ingesting gravel or rocks.
But it is a ditch pump.

[USMC2010]

Every other year, I've never seen one degraded at that length of time.

 

[Bigbore500r]

Every other year. I have a crank driven brass sea-water pump, it’s a 502 Volvo. The housing is circular, so the impeller doesn’t conform to an oblong shape like the mercury pumps. If I had a merc sea water pump with the oval shaped housing I’d do it every year, they like to shed teeth and blow apart after sitting all winter stuck in one position

 

[Icky]

Every year, use the old one as the back up as it still is in good condition

 

[Willie B]

...I have a rubber impeller still in its original plastic bag...am I going to use it...hmmm???...maybe not since it is probably 14 years old...

...Glenwood has lold me..If you bend the blades and there is no sign of cracking...use it...hmmm???...Dunno???...

 

[Socalx09]

What are you guys paying for an impeller service assuming you don’t do it on your own?

That’s bad ass to know, being i just bought a VVM, can’t wait to get it and play with it.

It's pretty nice. Gives some peace of mind being able to see exact numbers on things. If you have twin engines, it's a bitch to get set up. Have to get junction boxes and all sorts of cables. Also had to reprogram one of the engines to read as a port engine instead of starboard (or maybe the other way around, can't remember which). All of that fun added about another $500 to that little project. But if it's a single engine, pretty much just plug it in and go.

 

[Chris Lapoint]

Yearly on the flatbottom v-drive and I always have an extra one in the boat box
Every Other Year on the wake boat, mostly because it's a pain in the ass since it's also a v-drive the raw water pump is up against the transom/exhaust hoses.

 

[HowardRC]

Yearly. The old ones always look fine when they come out, but I just do it for peace of mind.

 

[Done-it-again]

every other....502 mag

God the Volvo impellers are SOOOOOO much easier to change.

I've never had a Mercruiser impeller come apart after sitting all winter.. or ever. This last one I changed last week was in the worst I've ever seen on any of my boats. It just had some visibly worn edges. I had to stop the boat in the shallows at the mouth of the river last season and sucked in some sand.

Def a design Merc should copy.

Helped a buddy of mine change out his.
Mercruiser direct drive ski Malibu.
He found one in Kingman in stock, but not Bullhead. Looked like it was on the shelf for 15+ years (in the Kingman heat). Greased it and everything, lasted 10 minutes. Came apart like cookie crumbles. Ordered one online, rubber was still very pliable. 4 seasons so far, never a problem. ~35+ hours a year.
