Stick with the two stroke.

TWO STROKES RULE!!!!

Dont have to tell me, I have 200 s troke HP powering my boat

Look here for a chart 2 stroke vs. 4 stroke

I know I'm kind of slow, but what exactly is that chart supposed to
illustrate?

it shows that if you use your motor very little (which you shouldnt!)
you will have used less oil with the 2 stroke as you had with the 4
stroke.

It also shows that about 55h run time a 2 stroke will use AS MUCH oil
as a 4 stroke NOT MORE. This is based on 200 HP Merc optimax vs 200
HP Merc verado and a few other assumptions.

It shows a (who makes them now?) ETect which uses almost under all
circumstances less oil as a 4 stroke.

This is all based at 4250 ROM average and does not show anything else
like environmental or cost issues.

I looked into this to find out if I have to feel sorry for buying a 2
stroke and burning ****loads of oil or if there is little difference.

I am happy with my decission to get the DFI
