1995 Evinrude 200 - XD-100 or XD-50?

[Classic57b]

Recently purchased this boat\motor. I have never "de-carbed" a motor and I can guarantee you this motor has never been de-carbed. The previous owner never did any maintenance.

So, I assume this motor needs a good de-carb and I'll do that at the beginning of next season.

I have been reading quite a few posts on the synthetics and blends

A couple of questions.............

I plan on changing to either a synthetic or a blend. Will either be a problem in this motor?

Can I mix the synthetic or blend with "regular" 2 cycle oil during the transition?

The XD50 will be just fine for that motor and yes you can mix the oil. I would run it down to 1/4 tank before mixing.

I would also change the carb bowl drain plugs to the newer plugs with a tit on 'em and change #2 carb high speed jet to one 2 sizes larger to keep that engine healthy.

Thanks a bunch. The high speed jet change I assume will help keep #2 cyl cool. Is #2 the top port or starboard?

What is the reason for changing the carb bowl drain plugs? Would you happen to have a part number for the new drain plugs?
