Impeller/Water Pump Replacement Often?

[jasper60103]

are there any good "how to's" out there? I'm somewhat mechanically inclined, but never have done an impeller job before. any leads would be appreciated along with a good source for parts needed to get it done w/o having to wait on more parts.

TN,
what kind of motor do you own?
Model and year would be helpful.
I'm familiar with OMC 2-strokes, but not the others.

Have an 04 Merc 60 hp 2stroke, bought it new, on a tracker pt175 as a package deal. Never had any problems so far, good stream of water, but this could be a good winter time project for me. Thanks

Well, I'm not familiar with Mercs, but I did some searching on youtube.
Does this look like your motor?. Hope it helps.

that looks like it 'cept mine is a 60hp vs a 50. Thanks, that should get me going in the right direction.

Is there a good source for parts available. Local dealer would probably be alot higher but can use them if needed. Thanks again.

For ordering parts online, I like marine engine, boats.net and iBoats. I found that Boats.net usually has better pricing on OEM parts than my local dealers, even with shipping.

thanks for the help, will start to get the parts together and do it over the winter time.

My first boat had the same impeller from the prior owner (I think I was the third or fourth owner). I ran it for almost three years before I had overheating problems. This was my first motor boat so I can claim ignorance! :mrgreen:

After ordering the lower unit kit to replace the impeller, I found out that there are a lot of other seals in the lower unit. It helped me to get a pilot bearing remover to take out the prop shaft seals and the drive shaft seals in my particular motor.

Ain't it fun?

Another thing to consider:
Some impellers will chip and release small parts of themselves. Where do you think they will go? They will flow into the cooling channels until they get stopped at a constriction. They will then reduce or stop flow of cooling water at that point and further 'downstream'.
Not good, and possibly about impossible to remove if you don't know where they stopped!
Change the impeller while it is still good...make sense? Logical?
I wish I could claim this wisdom but a friend who is an aircraft maintenance guy brought this to my attention.
Makes me want to change my impeller often...at least when recommended by the manufacturer!
