Working on the Tinnie

**Chops** · 22nd January 2014, 06:51 PM

Its been about 4 years since my little boat has hit the water

, and I'm in need of some water adventure

So time to get the girl organised.

So the other week, I spent a day cleaning her. Using a preasure washer, blowing out the leaves, dirt and moss

, and the old matting stuff I stuck on top so I did'nt slip, it was a massive job

, but now its all good. I've emptied out the old fuel, which did'nt look too healthy I might add.

So, after some discussions with a few mates and dealers, it had been sugested I replace the water pump before even attempting to start her.

I dont have any manuals or anything, so in preperation I've checked out a few Tube vids on how the pump is replaced,, looks pretty basic

Today after work, I called into the boat shop on Springvale Rd,, (daydreamed whilst looking at some really nice new boats

,, wish I was wealthy

), then went and purchased a new water pump.
Genuine Yamaha one to suit the 25H,,, $55.

I know you can buy them much cheaper through ebay etc, but they're not genuine, and the previous owner of the boat said he had problems when he went down the "cheap path". So I'm best not to temp fate

Cant believe how small it is though. Not quite too sure how this poor little thing is going to do the job,, but ah well, we'll see what happens. If all goes to plan, will do the fix this weekend

I'll see if I can remember to take some pics as I go too

Any of you guys change over your own pumps often, or do you just send it to the shop to be done?

Good to hear your getting back on the water. I don't think it will be a big job to change out the water pump on a little outboard as you said youtube is your friend. Also check your fuel lines make sure they haven't become brittle. Look forward to your trip reports.

Goodluck with that.
Australia day came a weekend early,will be working on getting mine fixed.Would have been out on the water if I had time to sort it.

in the past I have used the shop, I believe a water pump every 12 months is a good thing, regardless of use, if you wish to go out. So a good exercise there, something I will need to do in the future.
Perhaps some new plugs also.

That feeling of hitting the water is so grand, glad the inspiration has come round for you.

Jason.
When you say a waterpump per year,do you mean the impler???

Thanks Jason,, yeah, the "bug" if you like, has kind of hit me again. It's just work, moving and what seems to be general "life" stuff seems to get in the way a bit. On the river up at Albury, a lot of my time on the water was spent sleeping

. I find it very relaxing in a boat.
So with a few of the right people around you, poking, podding etc, it seems it will happen again, and reasonably soon. Have just finished cleaning out the car, and am about to wash it,,, then will start on the pump

Andy, yep, they mostly seem to recommend replacing the impeller once a year. It can come as a kit which includes a new insert cartridge, plate, impeller. A couple of other things like o rings woodruff key etc should be there also. The kit is probably twice the price of just the impeller, but it ensures all mating surfaces to the impeller are in good condition and working well.

Mine has had 2 impellers during my ownership.Havent quite cracked 50 hours myself.

Been working on the boat today, but had to wait for the sun to go behind the house,, bit hot here today

The first pic is the new pump impeller and associated parts. Looking at it, my first thought was,, "how tiny is that?"
So, I start pulling the leg apart to get at the pump,, all good, too easy. Forgot to undo the gear lever at first, but once done, a very easy job.
So with the leg set up on my table, I start to dissasemble the unit. Looking at it, I'm starting to wonder just how this all goes together. I can see a "round" housing

Oh well,, maybe all hidden underneath,,,,,
Undo the three screws holding the housing,, just knowing where this is all going

Ohh look at that,,, everything is round,,, not square

So ends this part of the lesson for this week boys,,,

On the other hand,, Andy, this is why we do this yearly, bianually if in salt water. Check out the sand in the impeller unit. On inspection too of the impeller, it is shagged well and truely. Quite brittle in sections (towards the tips mostly), and the guys were right, if I had started it without changing, it would have broken off and gone into areas its not supposed to be in.
Not sure if its a problem or not, but I'm seeing the cup section looks to be painted with something, which is disintergrating as well

Dont forget though, my boat hasnt been in the water for like 4 years now, so this time out of "lube" so to speak, wont have done the unit any good at all. I'm not sure if I was to keep it filled with water whether it would change things at all. Like keep it in a rubbish bin full of water. Good excuse to start it every so often too I spose.

So,, I'll finish cleaning it all up, chase down the correct pump,, and then finish fitting it all up
