I assume you mean the only place local to you that had one in stock because there are many sources online that stock the pump for immediate shipment.

Since the 4-108 was used in lots of applications besides marine (I have a tractor with a 4-108) you can find parts at tractor and equipment dealers, often at a significant savings since the parts don't say "Marine" on the box.

Westerbeke 46 IS NOT a 4-108 clone.

It is a 2.1 Liter Mitsubishi 4DQ5 manufactured in the 80's and early 90's.

Here is the problem with Westerbeke Parts Dealers. They have territories, so one can't sell outside of their territory. All of the dealers mentioned are good dealers.

That being said, for a coolant water pump, you can find the bearings fairly easily by calling a tractor shop and telling them you have a 4DQ5 as a last resort when Westerbeke can't run down the parts for you.

PM me if anyone needs any used parts for a W46.

Is the seacock open? Thruhull not blocked? Is the impeller turning?

I know nothing about your engine but on my Volvo there is a hard plastic key that connects the water pump shaft to the gear, apparently to protect the engine if the pump jams. I have been advised to carry a spare and I do. If your engine has a similar design, this key may be broken. With a broken key the impeller does not turn and the pump does not pump water.

The other possibility is that there are broken vanes from a previous impeller blocking water passages somewhere.

Penny,

Work forwards. Chances are it is in the strainer or clog at the through-hull with something growing or getting sucked up in there. If you are sure the impeller was installed correctly with a new gasket.

1. Check that the through-hull is not clogged.
If the seacock is operating correctly and in good shape, close the seacock and remove the hose. Open the seacock and if water is coming out, go to the next step. Put the hose back on and replace the hose clamps with two new ones. If water is not coming out, unclog the through-hull. You can sometimes blow it out from inside the boat.

If you have the grate strainer type through-hull, you need to dive the boat and clean it out from the outside.

2. Check the strainer. Close the seacock and unscrew the strainer bucket and remove it. Clean it out and put it back together.

3. Just to be sure, raise the hose from the output of the sea strainer and fill it with water and look at the pump for any leaks. If no leaks, install the hose back on with two new clamps.

If the engine was running hot before, then you may need to clean out the heat exchanger. But again, no water, fresh impeller installed correctly, usually clog before the pump.

Also check the following one by one:
Heat Exchanger
Exhaust elbow
Water lift/muffler

Any of the above could have a blockage.

I've just had the same problem in my Paguro gennie (a Faryman engine with a Johnson waterpump).

First thing I checked was the impeller, obviously, which seemed OK. Then through the whole system looking for blockages, even back-flushing the engine. No joy.

Returning to the impeller, I find it IS knackered. Although the rubber impeller was whole, the threaded cross-pin was simply ripping inside and not really turning the impeller at all.

Worth double-checking?

[Have tried to attach a pic of the unserviceable, free-spinning impeller...]

As an aside (and not wishing to hijack this thread) has anyone else had this problem with Johnson impellers?

It seems a very cack-handed way of securing the impeller rubber.

Now I'm just waiting for the next one to go the same way...
