was hoping I could get some tips on what maintenance you all carry out on your pups.
How often do you grease the nipples? wind down the grease caps? how to check sump level?
how to fill the sump?
any little hints or things to do or watch out for- I would really appreciate the help!

Hi Peter, The following reflects the maintenance schedule of a basically slack Blaxland owner but one who has seldom had any problems with his motor. Sometimes I go for months without using my boat.
I use my boat in salt water and it is stored on a slipway which is a very salty environment.
I wind down the grease nipples about 3/4 turn at the start and end of each trip (rolling the motor over once or twice after doing so at the end of a trip if I think of it).
Other tasks at the the end of a trip:
- Spray the motor down (absent the magneto) with a protecting spray. This is aimed at protecting it from salt.
- Fill the fuel tank - making sure to drain any water (condensation) when I go to restart it and at lerast stirring the fule if not replacing it when I have left it for some time.
- Take the magneto home and store in a warm dry place. When I was a kid my dad used to store them under the stove. Mine survives in my workshop.
I have never done anything with the sump of my current motor in 20+ years but note the manual does specify a small quantity of oil. I know that this must not be exceeded and it really should not need changing but I stand to be corrected on that.
I am basically too slack to freshwater flush my motor because I found the plumbing requirements were too complex and inserting extra fittings means more chances for something to go wrong when you are at sea.
Experience has taught me to avoid running the boat in shallow water and sucking up sand or mud which will settle in the water chamber (look for No. 1 pot getting hot but No 2 running fine).
Hope this helps.

Hello Peter ,
Adding to Laurie's good advice-
I am not so much experienced but enthusiastic .
The sump as such is dry much like your two stroke lawnmower however it is a 'splash ' type which takes the oil (not the current two stroke pre-mix oil) to finely lube and add to sealing for compression .
Some say it is not necessary ?
To add oil to the sump you can drizzle it through the the carburettor horn while at fairly high revs .
It will blow some smoke so head upwind .
Most importantly review all you can see on the Blaxland heading on this site .
You won't be able to sleep for ages !
There are many experts/experienced contributors who can advise later but for now relax and take it all in .

thank you Laurie and Neil- appreciate the advice... i must admit i have been guilty of spending too much time on this site reading old posts! when i bought the boat, he had red marine grease for the nipples and the wind downs, but he also had a small oil drop tin with clear oil next to the engine. i couldn't really work out where he used this and for what reason. unless a couple of drops were placed on the shaft?? and ideas?

Suggest that the oil can was for lubricating the water pump jounal. There is a cup-hole in the big end of the connecting rod for the water pump. if let go dry it will gall the shaft.

Gentlemen, Yes, the oil can is used for lubricating the water pump journal (saddle bearing). There is a small hole in the saddle for a drop or two of heavy oil before starting. The same oil should be used for lubricating the magneto drive (two or three drops). There is some discussion about what to lubricate the clutch with but the most important thing is not to over-lubricate it. If it continually slips I suggest pulling it apart, cleaning it and putting it back together.
