impeller change

[oldjeep]

Fwiw, I never have bumped the starter to remove the impeller. I soak it some wd-40 for a couple mins, then use some vice grip needle nose players and it pops right out.

FWIW, the way I got mine out was a set of vice grip needle nose and while I was pulling on it I used an allen wrench on one of the crank to pump bolts to turn the motor a bit. Took about 1/3 a turn before it released.

And just in case anyone is wondering, those Johnson impeller housing bolts are $3.75 a piece. I bought 4 so that I don't have to run over there the next time I drop one

Anyone using brass or stainless thumbscrews like these?

So did you find a place to buy these thumbscrews, Ben?

[formulaben]

Finding them in small batches has proven a touch difficult...but I think McMaster Carr (website down at the moment) will have hem in big batches...*cough* *groupbuy* *cough*

I did find this auction on ebay though. I *think* they are the right size?

[formulaben]

My idea was to get a set and then tether them together and then to the pump with thin stainless steel cable and fishing swivels so that you can't lose them.

According to this, they are metric thread with a standard sized head.

Hmmm...I saw the #10-32 x 3/8" size here:

Looks like I'll have to measure my own just to be safe.

Well, M5/.8 and 10-32 are awful close in size.

[formulaben]

Any reason these wouldn't work?

Still not sure if the screws on my pump are standard or metric...

Metric threads forsure. I'll keep looking for an exact matching thumb screw. Took my other finds down so no one is mislead.

This one is the correct diameter and thread. They have 6mm long, 10,12,16

Subscribed. I'd be in for a dozen if they'd work. Need to do my first impeller change and not really looking forward to it.

Can't believe my dealer just quoted me 180 dollars to do this simple job.

I'll be doing it myself that's for sure!

Did mine a couple weeks ago first time popped right out with the impeller tool I forgot the WD-40 step so It took a little bit but then it popped out looked in great shape I will use it as my spare the tool was nice and you can never have enough tools might be able use it on something else!

Or try doing this.

I may put wing nuts on there if I remember to buy some at the hardware store.

They work but are a little shorter than the original. Not sure if they'll catch with a fresh gasket.

You have a hex head, mine are flat screwdriver head...I wonder if they are different sizes?

I may just take you up on that. I have been reading how much harder it is to get to on a VDrive compared to a direct drive. I changed a couple on my BIL's eschelon and it was a PITA both times. I haven't even looked at where it is on this boat. Isn't the recommended interval every two years? I know it's relatively easy and inexpensive to change but is it worth it to change it early vs. just carrying a spare for if it goes early?
