better choice 2 stroke or 4 stroke?

Which is exactly why I cautioned about powering in big seas. Many of the older Mariner 2 strokes were available with low pitch props too, just ideal for pushing workboats and large displacement vessels.

Regards, Andrew.

 

Typhoon,
No, a larger area for a larger propeller and lower gears would be necessary to get to "ideal".
Frosty,
We've had a real mild winter here in Alaska so I'm not even frosty. The old two stroke motorcycles Suzuki built had the most sophisticated oiling system. They injected oil directly inside the engine to many critical places and varied the quantity relative to both throttle and rpm. The effective ratio went from 20-1 to 200-1 and they would smoke a bit under really heavy load but by then you were goin so fast the screamin air just about sucked the helmet off the top of your head. And Wynard, when they first came out we too were premixing also but soon stopped as oil injection quickly developed a reputation as bullet proof.

Hey Easy
Have you looked where a late model E-tec injects...

 

Power,
No but I'll bet it's opposite and directly across and very near the plug.

Sorry I meant the oil in reference to the Suzi post.
Etecs now also direct the oil to the crank like the old jap oil injected engines
but they have a computer driving the pump these days

 

Power,
Thanks. I'll be happy if the pistons get enough oil high on the exhaust side.

Here's an article in German about modern 2 stroke vs. 4 stroke, for those like Frosty who can detect a little Austrian
