Mariner 4 stroke 90 optimax

[tom russell]

How economical are these? How economical would they be compared to a yam 1988 autoloube 2 stroke?

[CJL]

Optimax engines are 2 stroke not 4 stroke.

How economical they are is largely down to what you attach it to and how you use it.

However I've found they are pretty good on the juice when compared to four stroke engines.

Yeah Optis are about the same as a four stroke, but you have to keep putting oil in which adds to the cost!
