Re: New to these engines
The model ID 'DT' says Two stroke whilst 'DF' is Four stroke.<br /><br />The 9.9 comes in plenty versions and I think it is safe to say the oil tank in yours is for an auto-blend system.<br /><br />When you start it you'll see a white smoke (especially when cold) which is a sign of oil in the gas. If you see no smoke at all, the oiling system needs cheking ASAP. I haven't heard of any weak points in Suzis' oil mix'er though.<br /><br />It takes nothing more than normal care to use an outboard: When starting keep rpm at idle or just above for approx one minute. Allow it to idle for a short while before engaging gears (which should always be done in one, firm but gentle movement). If your prop is right, you won't be able to turn it at too high rpm even at full throttle (your prop is right if it runs within rec. rpm range at WOT).<br /><br />The manual will state best practises for use etc., but one point so focus on is that you must supply plenty cooling water whenever starting the motor. Either by muffs, running it in a barrel or, ofcourse, at sea. It should show a tell tale to let you know water is pumped around inside the water jacket - if not, the water pump impeller needs replacement. On muffs or in barrel no more than 1500 rpm (high idle) is advisable.<br /><br />Other than that you can run it, at least until you get the manual.
