Yamaha 20hp

[SeanM]

Hi all, this is a great forum. Very informed people here. thanks for all the knowledge I have already gained.<br /><br />I have a couple of questions though. I recently obtained a 20 hp yamaha (2yr old)wiht very few hours on it. I was looking at Yamaha's web site and noticed they say to mix oil at 100:1, is this for just the 2003 models or should I be using that for mine to?

Yamaha says 100:1 since 1983 or so. <br /><br />What is your problem? <br /><br />Check your owners manual for the proper mix. No manual? Call your local dealer.

Hi SeanM<br /> 100-1 fuel ratio only with YAMLUBE!.<br />most other makes of 2 stroke oil are for 50-1 ratio.

Thanks,<br /><br />I find it does seem to be running rich at 50:1. ie. too much smoke. I have not been using yamlube, does it make a big difference?

On my yamaha's I use Yamlube at 100-1,when I did<br />use some fuel mixed at 50-1 for my murcury using<br />Quicksilver oil it smoked lots.
