To be honest chops on smaller 2 strokes for my use i will usually remove the thermostat altogether. They will run a little cooler but up here thats not an issue and the thermostat by its very nature limits good flushing.


Pilbara that is some good going build up you have in your cooling passages. I would be yanking the leg and power flushing the system from the draw tube with those anodes and the thermostat out to flush that stuff. Perhaps even consider some Salt-X or equivalent?

Steve leg was dropped and was all done this week. To much use and a little bit of abuse. Will try a bit harder this year to maintain along the way.

The killer in my experience is week long camping trips.
Engine gets run usually in pretty average coastal waters with mud and sand thrown around
And then doesnt get flushed till end of the trip!

Yours looks like a grey powerhead, so Im guessing a yammie 4 stroke.
At least you can rest assured the pro operators run them for upwards of 2000 hours with minimal servicing and never really getting flushed so the anodes likely do the job of prptecting the bits that count. But regular servicing with liberal use of antisieze makes servicing quick easy and painless

Alright my learned friends,,

Have done everything I can think of in order to preparing her for starting, as in checked plugs, drained and re-primed fuel etc, bucket of water to sit the prop and water intake in,,, but now I have a problem with the tiller handle .
It seems to be jammed in the "Up" position.
I have pawed all over this, and can see/feel nothing. Theres no cogs to get jammed up, the throttle control is cable, and works fine, goes in/out of gear. Its just stuck up.
Frustrating, as I need it down in order to try and start her. (Its a "hanging on/leverage" thing)

Any ideas.

I forgot,,
It hasnt been getting tight or anything, it just seemed to go up, then wont come down. Its almost as if its been locked up by some kind of connecting lever or something.

Yeh that exactly what happens I'm home for a week at a time and my engine only gets flushed once when I put it away so that's a fair bit of running on the flats in not the best of water. In saying that I have over 700 hours on mine and it hasn't missed a beat 115 suzuki. Most of the guide boats hear also run the suzuki and have well over 4000 hour. The problem most people have is opposite to what they think is doing the righty by minimising there run time on the motor keeping there hours down. I would buy a motor with 1000 hours from a guide over a engine the same age with 200 hour that's been sitting in the shed.

Can you take a picture of the tiller arm ?

Chops,
does the tiller pivot have a grease nipple
could it just be seized up crusted grease
straight petrol will dissolve old grease quicker than most other things, just dont use a lighter for illumination

A couple of pics.
Theres no grease nipple that I spotted for this hinge. Prior to it locking up, it moved very freely with no signs of catching/scraping or anything, quite loose in fact.
Its a bit hot out at the moment,, she's sitting in the sun, so when it goes over the house I'll get some CRC or something and give it a spray.
