I have plucked up the courage to try and change the gear oil in my old Mariner 40 but I cannot work out with is the correct gear oil to buy.
I have been searching old threads and the internet in general but now have got stumped!!
From what I think I have learnt the high performance one is synthetic and the other not so the two cannot be mixed, but I plan on draining the old stuff out so would this matter?
The serial no of the old beast is "6E9 L 407462" if that helps anyone and i think it is a early 90's model.
I have been checking out previous threads and absorbing all the good advice and its sounds simple enough (famous last words
), i plan on getting a pump, heating the oil in some hot water and just pumping it in until it comes out the top...
I have seen this on ebay and it seems like good value?
