[skelz]

Hi
I have just this morning purchased a 4.5 glass half cabin with a 70hp 2 stroke mariner on it.

My question is what is the best fuel/oil mix for the old girl ???

As this is my first boat any other tips on mariners or outboards of thios age greatly recieved
Thanks

Congrats on your new purchase you will have a ball I am sure. i cannot give any unique model info sorry only to run the motor on 50:1 TCW3. Yamalube is in my opinion the best mineral oil for the price (gotta be to keep a 2 stroke together for as long as Yamahas seem to last at 100:1 ratio).
If you want to go up in quality try the new full synthetic oils some of these state they can be run at 100:1 in old motors and confidently at 80:1 not sure which are imported in to aust ATM. Evinrude has a good synthetic also. nq
