Thread: Working on the Tinnie

Just plug the hose in at home and save a trip to the boat ramp for when you have the rods and bait handy.

I have a set of them for cleaning.
After chatting with my great mate Graz Im looking for some sort of tub to do my testing with.
With muffs you wont know if the impeller is stuffed as the water is pressure fed.

Yeah, I've got a set of muffs, but have only used them when I've been camped somewhere I have access to fresh water,, van parks etc.
I normally just use a 60lt rubbish bin filled with water at home.

Chops I know you have it all apart now but a suggestion for perhaps next time or for others.
Annual look at water pump is usually a good idea.
One thing to include while you have the lower gear case off. Find the water draw tube, most will allow your average run of the mill garden hose to slide over. Slide the hose over the draw tube.
No take off the two bolts that hold the thermostat housing (make sure you have a new thermostat sealing rubber and new gasket they will need to be replaced)
Now tuen on the water (do not run engine) water will flood the cooling passages and poor out the thermo housing giving it a proper flush.

Now is the time to also change water jacket / head anodes if fitted.

Trick with installing the water pump is that the drive shaft generally always turns clockwise when looking down. So have the impeller pinned by the woodruff on the shaft with a new wash plate and new o-ring underneath. Slide the water pump down the shaft then with a touch of anti sieze on the impeller blades turn the shaft clockwise and slide the pump over the blades. They will slide into position.

Probably enough rambling

Thanks Steve,,
Bugger, I wish you'd said that a tad earlier

Next time I will do as you sugest. I've been trying to find a manual online, but havent had any luck so far
In all the times I've run it, I've had no problems with her other than a flooding issue, and it was my own fault for not paying attention to how I tried to start it. I have to hold the handle juuust right,, well,, sometimes when your keen to get going onto the next spot, you tend not to really concerntrate

We'll see how I go in the morning when I try and kick her over.

Good advice Steve.

These are the head anodes that come our of my engine after a year.

Hi guys,
Is it possible for one of you to take a pick of where these are on the motor please?

Most two strokes are very similar in design, so even if its not a Yamaha you take a pick of, I should still be able to check it out. Mines only a 25hp, and very old, but it's done next to nothing in salt water since it was fully rebuilt several years ago, so I'm not overly stressed, but would like to check anyway.

Thanks in advance if you can help with this guys.

Marcus,do you have the original owners manual????
I looked here,the oldest online version is 1998,it may help.
