Suzuki DF90 water pump service

[limeydal]

Just got "Bayshots" back from a water pump service and looking at doing more of the maint; myself. Mainly due to the cost Just spent $350.00 on a new pump service ) They replaced the impellor etc.. and also the thermostat.

I was a little concerned as I had the impellor replaced at the start of the season and it had already failed and the engine had overheated.

So my question is,is the water pump technicaly difficult to service.? I checked online and it seems like just dropping the lower end to access the pump housing.
$45.00 for a repair kit seems much more bearable than an annual $350.00
The full repair manual is about $60.00 for this model, so maybe that would be a good investment ,now I have about 500 hours on the engine

The first thing I would do is find another service dealer. That job is $50 parts + 1 1/2 hours labor. A factory service manual is always a great investment.
First time you do it it will probably take you about 3 hours.

Water pump impellers are very easy to replace and yes go purchase a manual such a Clymer manual.
You might want to consider replacing your impeller every year.

Another easy item to accomplish is a lube and tune as mentioned in this cross post. http://www.sandiegofishing.com/buddy...t=changing+oil

Craig,
thanks for the link. Some interesting local stuff on there. Surprising what's around and you never know.
Only a couple of Suzuki dealers here in San Diego, so definately be doing more of my own maint: going forward. (just got lazy in my old age )
Sending of for the manual right now; should be useful as I have the complete spare lower end from a previous "mishap" so have a few new spare parts for the future, that may come in useful.

If you've got a reasonable amount of mechanical knouse then the cheap CD manuals from ebay are worth a go. All the ones I have are scans of factory manuals and more useful than Seloc paper manuals-though Clymer are still excellent.

Changing the water pump isn't a hard job BUT Don't use the antiventilation plate as leverage whatever you do. It'll break. As well as changing the impeller and gaskets you need to inspect the inside of the impeller housing for scoring and replace it if badly scored.

The hardest part is supporting the weight of the leg/gearcase whilst you undo the bolts and disconnect the speedo pipe. Putting it back together is simple, but it canbe hard to line up the gearchange rod and slide it together gently.

What exactly happened with your overheat? Was it the impellor, and how did it fail? I had a couple of overheat probs but the impellor always checked out fine.

Erin,
I do a lot of idling ,while drifting around getting shots. So several times at idle, the alarm came on and the water out the pee hole was obviously greatly reduced and extremely hot.
Once I was up to speed, the flow increased and cooled the engine down quickly. I saw the old impeller and the vanes had "bent" quite a bit in the 9 months since new. So not sure if I just got a bad one !
Nos/ thanks fo the ti! will be sure to take my tme the first time. (hope that wont be for a while though !)
cheers Dal
