Good evening all.even though our 225 vro motor is in good condition (recently serviced and tuned ) but it smokes quite a lot when started in a test tank, the vro has been disconected and we run a straight 50:1 If fuel is kept for a few weeks, will the petrol evaporate off making the remaining fuel even more oil rich causing this excessive smoke, secondly what sort of consumption can be estimated from this motor, mounted on a 20 ft deep vee cabin boat using a 14 1/2 x 21 pitch propellor we are able to hit 5300rpm to 5400rpm quite easily.we have been told that the VRO supplies less oil at idle and very low rpm ? maybe that is why the motor smokes at startup ?
Kind Regards William Wright
