Peter Nelson Posted September 3, 2019 Share Posted September 3, 2019 Hi All Just wondering if anyone uses an alternative oil other then yamalube in the gearcase. Got a 70h 2 stroke I think around 2006 model. Not sure what viscosity it should be. Cheers Link to comment Share on other sites More sharing options...

Rebel Posted September 6, 2019 Share Posted September 6, 2019 Hi, Yamalube 2M. is the go. Do not use CAR OILS. Look up the Yamaha Website, very helpfull. Cheers. Link to comment Share on other sites More sharing options...
Peter Nelson Posted September 6, 2019 Author Share Posted September 6, 2019 I've been looking at Penrite marine gear oil, wasn't sure if compatible or not Link to comment Share on other sites More sharing options...
Rebel Posted September 6, 2019 Share Posted September 6, 2019 Peter, Be carefull. You don't want to stuff up. Motors are expensive. Cheers. Link to comment Share on other sites More sharing options...

Buy a pump,look after it and it will serve you well. 1 Link to comment Share on other sites More sharing options...
noelm Posted September 7, 2019 Share Posted September 7, 2019 You need to buy an extra bottle to do it buy squeezing the bottle, because you can't squeeze it all out , so you need the extra one, not too sure why you don't use the Yamaha oil if you're worried. 1 Link to comment Share on other sites More sharing options...

Just looking at alternatives since I can by the penrite around the corner. As long as it's got the same additives, properties and is cheaper why not I guess Link to comment Share on other sites More sharing options...

Another option is filling a large syringe and injecting the oil in . I've used both methods for various applications and they do work. 1 Link to comment Share on other sites More sharing options...
kingie chaser Posted September 7, 2019 Share Posted September 7, 2019 I bought a pump recently when I changed my gear oil. Dam it made life easy, so worth the $20 to me! 1 Link to comment Share on other sites More sharing options...
bman Posted September 23, 2019 Share Posted September 23, 2019 Hi Peter, I would stick with the Yamalube. Its GL4 compared to the Penrite which is GL5. I swapped to the penrite and started to notice crunching in the gear box. I drained it and went back to the Yamalube and had no issues. I do have a mid 80's yamaha 2 stroke so the "newer" 2 strokes may be able to handle it. Bill Link to comment Share on other sites More sharing options...
dunc333 Posted September 30, 2019 Share Posted September 30, 2019 please get pump bottle filler sold by merc or yami lube with correct thread. and next oil change using any good quality marine outboard gear box oil you can refill origanal bottle so no air bubbels when filling cheers duncv 333 Link to comment Share on other sites More sharing options...
Nolongeramember Posted September 30, 2019 Share Posted September 30, 2019 (edited) I understand the reason why they SAY to pump the oil from the bottom but what is wrong if you just put in the specified amount from the top? Surely it would all flow down and any air pockets (if there happens to be any) will disappear as soon as the gearbox starts turning. Obviously, if less than the required amount goes in and the top hole is overflowing then you either wait for it to go down or turn the gears until you can add the whole amount. What about when you tilt the engine all the way up and then back down again? Same thing. Edited September 30, 2019 by Hateanchors Link to comment Share on other sites More sharing options...

Yup... you can do it that way. It just takes longer and is more prone to error as you are trying to fill through a small top hole prone to get airlocks... plus getting rid of the bubbles trapped in the gears that you mentioned previously which would take up space meant to be filled with oil, yes you can turn the gears and wait for the air bubbles to leave via the top hole... but then you'd have to meticulously measure the exact quantity of oil and persevere until you have poured it all in being careful to compensate for any spillage running along the lower leg as you try and get it into that small top hole (from which the displaced air is also trying to escape). Much much simpler and quicker to fill from bottom, the rising oil will displace any air, once the oil starts to seep from top hole, you know you are done, screw close the top hole and remove the oil bottle at the bottom - nothing will leak out as you have an air lock - replace bottom screw. Done. Also, if you are paying someone, mechanics charge by the hour ... which method would you rather they used? Cheers Zoran 1 Link to comment Share on other sites More sharing options...
Marrisy Posted September 8, 2020 Share Posted September 8, 2020 Takes way longer to fill from the top. As the air can't escape as well, and bubbles cause some oil to splash around. Link to comment Share on other sites More sharing options...
