View Full Version : New to team talk - old to mastercraft - Quick Impeller question

Hi All,

I am a proud owner of a 95 ProStar 205. I bought it two years ago and have enjoyed it thoroughly with family and friends. We put almost 200 hours on the MC over 2 years!

I have browsed team talk many times but finally became a member given that it was free. So needless to say I appreciate all of the helpful hints and tips that more seasoned owners have shared.

As soon as I figure out how to upload some pics - I will.

My question is in regard to installing a new Impeller. It seems like a pretty straight forward install but I was curious to whether or not there was anything I should watch out for, avoid, etc.

Thank you!

My Stars and Stripes is sufficiently different from the newer stuff that I won't give any specific pointers other than to change it every year with the hours you are putting on it.

Here is one of the many ways to post pics on this site.

1. Click Paperclip icon
2. Click Browse button
3. Locate the picture in your computer and click on it
4. Click Upload button ( to the right of the Browse button)
5. Once picture is uploaded (it will take a moment or two) it will show as Current Attachment
6. Click Close Window button
7. After you have entered text, use Preview Post button to make sure you selected the proper picture.

Welcome to TT. Do have the standard TBI motor or the LT1?

It's about as simple as it looks. Nothing special on that one

just get the impeller vanes rotated in the correct direction

SW MI .... anywhere near Paw Paw Lake? my buddy is there

Yep, pretty easy on a direct drive. Undo the 4 screws, carefully pry out the old impeller, put a new one in and put the cover back on with the new gasket.
Only hitch may be the old one might be a little tougher to get out if it hasn't been replaced in some time and/or the splines weren't greased.
You can use an impeller puller or grab the vanes with a couple needle nosed pliers, or pry out with a couple screwdrivers. If it's really stuck, undo the hoses and the brace that keeps the pump from rotating and rotate the pump back and forth while prying or pulling. Same can be accomplished by bumping the starter (disconnect the kill switch) between reounds of pulling or prying.
Coat the splines/shft with some grease or anti seize before installing the new one and next year it will pop out easily.

Direction of the vanes doesn't matter during installation. Once you bump the starter once they will all be in the right direction.

I keep to paint can openers in the boat to put it out. Works great with those little hooks on the end

Here are a few tips in addition to what has been mentioned.

1. Remove plate.
2. Using a spray bottle, squirt soapy water all over the old impeller and inside the housing.
3. Pull the safety lanyard and bump over the engine a couple of times to get things moving.
4. Use either paint can openers to get behind the impeller or a pair of needle nosed pliers on the hub to get it out of there. If you get it out in good condition, toss it in a ziplock bag and put it in the glove compartment as a spare.
5. Lube up the new impeller with a water based lubricant (yeah, that kind) to make things easier getting it in.
6. Be careful not to scratch the inside of the housing when removing or installing the impeller.
7. Use a little lube to hold the gasket in place on the cover plate.
8. Be careful tightening those brass screws. They are soft and break easily.

I recommend changing your impeller before the beginning of each season in the spring. It is cheap insurance. If you want to go longer, remove it at winterization. If left in during layup, the vanes can become formed to the odd shape of the housing, making it a less efficient water mover.

What I do is spray WD40 all over the old one and turn the motor over a couple of times. Impeller comes right out.

The only thing I can add is don't get too excited when opening up the package with the new impeller and gasket. I have torn up two new gaskets in the process.

Just a FYI, never use petroleum based products to remove or install impellers (says right on the instructions) Glycerin is what comes in the Johnson boxes I get. Easties method with the soap is the best.

Using WD40 to remove it is fine if you don't plan on reusing it. Which I dont.

The WD isn't good for the rear seal in the pump, it's made of the same stuff as the impeller. Use this for the install.

Any suggestions to make it easier on a v drive? I pulled the cover off without any problems but I have zero visualization. Any suggestions would be appreciated.

Well...if you have left over KY you know what you can do with that :D

Same here... that's the advice I got from Joe at MCOC when I couldn't budge it one time. I was using needle nose vise grips and couldn't move it. Popped right out after that.

Wire pulling lubricant might be another alternative. KY works really well though.

The warming kind or cooling kind?

I've heard that before. But Joe from MCOC was certified from MC, Indmar, Seadoo and a few other places. Knows his stuff, I can't imagine him steering us in that direction if there would be a problem.

All these teak and impeller threads are great, but I think I need to start a new oild thread.

Thanks to all for the helpful tips to all!

Quick question and this may be a dumb one - the boat is still winterized with eco friendly anti-freeze. Should I take it out first and run it for a bit before changing the impeller?

Nope, you might want to summerize at the house though. If something needs to be work on you can do it at home.
