leaking manual bilge pump

[iSailor]

I was preparing the boat for the spring and noticed that the manual bilge pump was leaking (at the pump it self). It was still able to pump the bilge out, but I want to address this issue before it is a big problem.

Not exacatly sure where it is leaking out of yet, maybe around the diaphram. The plastic mounting collar around the diaphram appears cracked as well.

Anyone replace or repair these?

Thanks,
iSailor

Yes, I replaced my pump.


One day I drained the water heater into the bilge........used the hand pump to

pump out had a real sore arm after and realized if I had a leak

I am not a big proponent of Paulj's approach. I get what he is saying about the manual bilge pump being difficult to pump while single handling and that a larger electric could be a big difference. But I am in the process of installing a second electric pump without removing the manual.

As far as the manual goes, I believe we have the 11.4 GPM manual pump and the replacement is available at Catalina Direct for $80. They also have a 28 GPM for $190 that is a drop in replacement.

I found a 28 GPM at a local marine consignment store for $20.

I would have to agree you should always have a manual pump ready in case of you are in a situation that you lose power and need to pump. I hope none of us are ever in that situation.

At the end of the season when I pump my water system I just use a pump that I hook up to my hand drill to clear the bilge.

Along these lines I recall someone saying you can add a Y valve to the water intake and use that as a backup pump. Has anyone done that? Would come in handy when winterizing the engine too.

I did this. Allows me to winterize the engine, flush freshwater through the engine every month and use it as a bilge pump in an emergency.

In not sure why somone would suggest this when,.. if its forgotten for just a minute or less, after the bilge is clear of water your impeller blades are at extreme risk of damage. Almost a certainty...

There are too many ways to connect a secondary bilge pump without putting a difficult to change and a very important part of the boats operational system at risk.

If the purpose of a second bilge pump is for safety and redundency, make it a dedicated stand alone system so it can be used as such and not dependent on another system of the boat to operate it..

Some may feel this is an extreme view, but it my opinion that if the primary and secondary bilge pumps are both battery powered, and the battery system should ever be shorted or otherwise compromised during the flood or event that caused the excess water, you wont even have one bilge pump in operation..

Years ago I did not pass the Coast Guard safety inspection because I did not

have a bailing bucket on board..............

The wye in the engine intake is pretty much a myth. Handy for flushing the engine, yes, but not so much as a bilge pump. The GPH on our little diesel raw water pumps aren't that great in the first place, and when the pump plugs up with bilge debris, now you're sinking and dead in the water. Not a good combination. As the saying goes, "The most effective bilge pump is a frightened man with a bucket."
Back to the original question, was water allowed to freeze in the pump body? With the temps we had this past winter, that could have happened where it never happened before. That would crack the pump and it's a spot that you might not think of winterizing.

Jesse, When you upgraded to the 28 GPM pump did you use larger hoses or just use the hoses that were there and also did you have to drill the extra holes?
Thanks

It takes the same hose.
