A needle nose pliars works great to remove the impellar. Grap one of the blades and wiggle slightly while pulling out.

Typically the gasket comes with the new impellar, if you need just a gasket they should be available at any MasterCraft dealer or authorized Indmar service center.

Skidim also has them...think they run around $20 w/gasket. Sometimes those impellers can be really stubborn. If you work some liquid soap in around the vanes, and in through the hose connections, pull the safety lanyard and crank the engine for a couple short bursts, that should free it enough to grab with a couple needle nose pliers. The old paint can opener trick somebody mentioned on here has worked for me too. Get two paint can openers (they look like a bottle opener on one end, with a small hook on the other) - you can fit the hooks in behind the impeller - one on each side - and wiggle it out. You can also put a couple screws into the rubber near the brass hub and grab onto those with a couple vise-grips. As a last resort, there is a commercial puller available (around $50) that works 100% of the time. Should have good luck with methods mentioned above, just be patient and keep at it. Be careful you don't put too much lateral force on the impeller housing, so as not to damage the seal in the rear of the unit. Good luck -

The impeller and gasket can be bought as a set and I wouldn't recommend replacing the impeller without a new gasket.

my impeller went out today in the middle of the lake, it cooked the gasket.
the only way to get back was 1 paddle, and a 3 minute idle in gear every 10 minutes...
the engine was hot, but I needed to get another mile and a quarter back to the dock.
I am going to check the oil to check for water in the oil to be on the safe side, then change the oil again to be safe.
I hope i didnt hurt the engine.... :( :confused: :mad:

When you do buy a new impeller and gasket set, buy 2, 1 for a spare to carry in the boat. Plus, a small tube or jar of vasoline or grease to lube it up with and it is only a 10 minute job. I have changed 3 on the lake for other boaters over the years and they can't believe how simple and inexpensive job it is and they all now carry a spare.

Be gentle with those 4 cover plate bolts - they're brass and very soft, and it's unlikely that your hardware store has replacements. Also, be careful how much yanking you do to get the impeller out. Off-axis torquing on the raw water pump can asymmetrically crush the seal on the pump shaft. They seem to be a little on the delicate side.

I would be really surprise if that 351 got hurt.
I doubt it.
Me think you're fine...:)

The cover plate bolts don't use a special thread but if necessary, stainless can be subbed. It's just better to use brass so the hole threads don't strip.

Once it starts to squeek when it's tightened, it's time to back it out and replace it. That's the sound of brass shearing, either threads or the screw's body.

thanks...
one other question, does the inside of the raw water pump housing have one side that comes in a little? (like not a perfect round hole?)
thats how mine looks???

bigmac
11-11-2006, 07:37 PM
Yes. That circular eccentricity is what makes the pump work. It should exist between the intake and output.

thanks, im going to try and fix it tomorrow, and check the oil for water... (God I hope not)

I know my local napa has marine parts, can i get the gasket there? I found a spare impeller in the boat, but it looks like the gasket isnt in the package?

DooSPX
11-11-2006, 08:56 PM
also, I would love to hook up a red light in the panel for over heating reasons. the alarm is not really audible when running the boat.
is there a way to tap into the wires from the sensor for the alarm and hook up a light?

Hoosier Bob

I already have the light but as far as the pulling of the imp I use two small allen wrenches and vice grips. I suppose two needle nose pliers would work just as well. Anyway good luck and replace often as it is cheap insurance!
Take care,

I found a spare impeller in the boat, but it looks like the gasket isnt in the package?I've never seen that impeller sold without the gasket. If there isn't a gasket, you might be able to get away with using the old one, or maybe you could make one, or form one out of silicone. Personally, if my local dealer didn't have one, I'd use the old one and order one (or more) from SkiDim for $1.82 (http://www.skidim.com/prodinfo.asp?number=68-5008) and put the new gasket in when it arrived. At the same time, I'd order another impeller (http://www.skidim.com/prodinfo.asp?number=RP061018), some Johnson Impeller lube, and some spare cover bolts (http://www.skidim.com/prodinfo.asp?number=68-5005). I'd think about an impeller pulle (http://www.skidim.com/prodinfo.asp?number=JAB50070-0040)r too, just to make sure I was never one of those guys that posts here on TMC about how they can't get their impeller out with the paint can openers or the needle-nose Vise-Grips.

If you're looking to get it locally, the pump is likely a Johnson 68-5001 and uses a Johnson 812 impeller. Malibu dealers are also very likely to carry it.

If you can find a schematic from a 93 you should be able to locate a sending unit, part number and led that can be mounted anywhere. I will look through my info and if I cannot find you will have to wait until spring when I can get to my ride. Yes she is in my garage but she is packed and covered! I am sure we can come up with something!:D

PS. I remember being a kid and hearing my dad b**** about "IDIOT" lights! He said the lights told you when it was too late and the gauges warned you so follow your gauges! The light that appears most important is the Trans light as it has no gauge. Just check you gauge every once in awhile and forget the light. You will see it coming. We have old rides so one eye on the water, one eye on the skier and one eye on your gauges should work just fine!;)

Your temp warning buzzer should be 12 volts - can't you just hook up a 12 volt red warning light across the poles to that?

HI Guys,

I'm also looking to replace the impeller on my 96 Maristar Vee-Drive, and found on Indmar's site that the replacment impeller number is 985009. My problem is I can not find that number anywhere to buy a new one. My local marine store told me to take the old one out then bring it to them. Personally I'd like to get all my agrevation into one day (changing the impeller) and not stretch it out into 2! LOL! Does anyone know what the replacement number is?

Thanks in advance!

IIUC, Indmar 350's have always used Johnson raw water pumps. You'd have to look, but if your particular pump looks like the drawing in the Indmar owner's manual, it's going to need the same standard Johnson 812 impeller that is used currently. Should be available at any marine store that caters to inboards. If not, any MasterCraft or Malibu dealer should have it. Note that it uses a spined shaft (or multiple flats, anyway), not a keyway.

Here's a key question though....isn't Indmar part number 985009 the thermostat?

Thanks for the help bigmac! I really appreciate it. I thought that was supposed to be the number on the impeller, but maybe I'm wrong. I do know when I google that number it comes up in Indmar's website that its an impeller. But when I tried t find that part I couldn not find anything about it. Hence my question on here. I will try that number you gave me!

Thanks so much for your help!

Looks to me like 985009 is a thermostat (see attachment below, from the Indmar owner's manual).

Look at this page (http://www.skidim.com/prodinfo.asp?number=RP061018) on SkiDim's website, see if the description fits your engine.

You're absolutely right! I will check out the website and order the impeller!
