need help with broken impeller shaft?!

Hi All! I have a beta marine 20hp (model BD722) and recently noticed a leak around the impeller as you can see from attached link (label A) impeller1 | Flickr - Photo Sharing!

But once I opened the impeller case, to my shock found a bit of the u-shaped head of the shaft broken off (label B). It is a really frail part!

There is a better pic here: impeller2 | Flickr - Photo Sharing!

I tried operating the engine without the impeller as I have a water filter/stainer on the intake and to my surprise found no water gets into the engine (newb!) So I now learnt that the shaft is part of the water pump!!! Any idea if i can replace the shaft or is it the whole water pump enblock?

thanks
Jay

Re: need help with broken impeller shaft?!

The impeller actually "impels" the water into the cooling system. No impeller, no water.
It may be my aged eyes, but I can't detect what you say is broken. Do you mean the screwdriver type slot in the end of the shaft?

Re: need help with broken impeller shaft?!

thanks Mike.

It is the actually the U-shape top part (the head) of the shaft that is broken.

So it is the part which goes through both sides of the pin that lies across the diameter of the impeller.

I suspect that I will need a replacement shaft if it exists and if i can identify the type of pump i have!

cheers

Beta Marine Raw Water Pump for 3 cyl BD1005 Diesel Engine

This might save you a few bucks but obviously there'll be some shipping involved. These pumps are typically Jabsco or Sherwood but best to check with Beta to be sure.

Re: need help with broken impeller shaft?!

You may find the pump manufacturer and model number identified on the pump cover (end plate) -- the thing you removed to access the impeller. If so, you'll probably find the shaft and seals on the internet.

While you have the pump case open you should certainly replace the impeller and gasket. It is good practice to keep a spare on hand and replace the impeller and gasket annually

Re: need help with broken impeller shaft?!

Seawater pumps can typically be rebuilt, but you may need a press to put the seals in. Hard do it yourself job without one. Bad news is they can leak, even when rebuilt, and I've had more than one yard discourage it. By the time you pay the labor and buy the rebuild kit, you are more than half way to a new pump. They are a wear item, so it may make sense to start the clock over.

Re: need help with broken impeller shaft?!

thank you all for taking the time to reply! here is an update ...

the jabsco water pump shaft will typically cost around €80 (inc. P&P) and a new pump (complete) around €300 - I can have one ma de at an engineering shop for around €40 - since the part is not a particuar precision part - I am going to go for this option!

In the meantime have put everthing back together as hoping to use the boat this weekend! Pump is fully funtional with one prong (and one broken off) and the impeller seems to do the job! Unless someone thinks otherwise will use it this weekend until I get the shaft hand made!

cheers
Jay

Re: need help with broken impeller shaft?!

There are typically bearings and/or seals around the shaft. I believe it is very likely that a new shaft will leak without replacing them as well. Even OEM parts reportedly will often leak.

Re: need help with broken impeller shaft?!

Hi there! So I got the water pump shaft manufactured at a local engineering shop and it cost me Ä40 (ca. USD50). Whilst at it, I replaced the two bearings, the two oil seals and the o-ring! Fitted everything in and as you mentioned earlier in the thread, the pump still gives a bit of a leak! My original problem was the leak + the shaft ... at least I solved one and will live with the other which I don't think is a problem!
cheers
