The two-cycle engine is much simpler, and lighter. Indeed, you will smile broadly when you open it up to see what's inside. In it's simplest form, the prime mover will have 3 working parts.... plus the gearbox, if it has one.
The two cycle will use more fuel than the four cycle.. about 1/2 as much again, particularly when worked hard. A two cycle outboard, like the motorcycles, realy drink heavily when thrashed.
If you are not going far, I would stick with the two cycle, certainly for use with your tender.
If you are going far, and not in a hurry, the four cycle is where it's at.
