Re: gas/ratio 1990 Yamaha 85
Hi,<br />Just as a side note:<br />If the oil injection system is disconnected it is in most cases 50:1 (fuel

il) that can be used.<br /><br />But when oil injection is in use there is usually a variable fuel

il ratio. For example most Suzuki 2-stroke outboards with carburators has at idle 150:1 and at full throttle 50:1.<br />So it varies with RPM.<br /><br />When You mix oil in the fueltank yourself You will usually get a little more oil then needed at lower RPM. That can for example be a slightly negative thing if you use Your outboard much at lower RPM like trolling. The spark plugs do not like that if I'm not misstaken.<br /><br />/Bo
