Have you ever read in any operators manual-
running out of gas will damage this motor?
I never have.
What’s the difference ?
Tubs.This applies more to multi carb motors as the top carb will run dry before the lower carb and no lube or fuel mix will be getting to the upper cylinder. Not so much of a concern on motors with a single carb.
There is more oil in a crankcase than that which is in the fuel.
Besides the surfaces that need lubrication some oil attaches
to the other surfaces like the crankshaft, connecting rods and
the block it self. When a motor sits over night you’ll get more
smoke than normal when starting one for the first time. This
is the result of that residual oil draining off and pooling it the
bottom of the crankcase. This oil gets picked up when the
motor is started resulting in that initial extra bit of smoke.
After the fuel runs out there is still enough oil remaining to
continue to provide adequate lubrication. However if there is
a manual or a service bulletin for any model 2 cycle outboard
motor that states running out of gas will result in damage from
lack of lubrication please share it.
