2 stroke / 4 stroke advice
Are you off your meds again :-)

In any engine with loose lube oil inside it, you can only tilt, carry and store it in certain locations. If, for instance, you were to store it so the oil ran up against the bottom of the pistons, oil would get past the rings into the top of the cylinders, after a time as they are not hermetically sealed. It could become hydrolocked with lube oil, which would bend the rods trying to get it past TDC on the compression stroke with the valves closed. If the oil in the crankcase ran out the crankcase vents in another position, what a mess. Cranking that would be running the engine way low on lube oil, the oil that ran out now missing from where it is needed. The permissible carrying and storage positions designed into the portable 4-stroke outboards is defined in the owner's manual. Check that before buying them. They are also much more complex and heavy than the simplistic 2-strokers with no valve trains, camshafts, etc. a 4-stroker must have. How far down the beach did you say you had to carry these beasts? It's also an issue. I tried to quote from Mercury or Evinrude from a downloaded owner's manual, but both websites tried to force me to install Flash players so they could run code on my computer to spy on me, which I will not permit, and, once that was bypassed, informed me I had to already be an owner to download an Evinrude owner's manual, making me question, "What are they hiding?", as it costs them nothing to let me have a look, being a potential customer.
