It should be 2 Cycle oil mixed with gas. You wouldn't have any oil to change unless your talking about the oil for the gear box.
on the cowl of my 1993 DT2 suzuki it states 100 to 1 mix.

enough oil is what you need
The ratio is 50:1.
The magneto point gap on a 2hp Yamaha outboard is 0.35mm, or 0.014".
Factory says 100:1 but reccomended by users is 50:1

How Old? I have a 1980 2HP Johnson. The Ratio is 50:1
You can generate electricity with a 27KVA alternator, a big wheel, and a 2HP motor, but you will not be able to even come close to generating 27KVA. The best you could hope for is about 1KVA or so, because a 2HP motor can only do about 1.5KW of work, and efficiency and power factor losses will make the output be even less.
12/2 with ground.
It would depend on the efficiency and design of the motor, as well as the operating conditions such as load distribution and friction. In general, a 2HP 4-pole motor may not have enough torque to lift 300kg vertically, but it could potentially move the weight horizontally on wheels or a conveyor. It's important to consider the motor's continuous duty rating and consult with a mechanical engineer for a more accurate assessment.
