200 hp Mercury EFI won't accelerate past 1600 RPM's

Would this be the stator? Its EFI so I'm hoping its not fuel....

I would think it would be fuel related before electronics . I have never seen a motor with a bad stator crank. fuel pump filters plugs etc start with the simple stuff first.

Better check fuel system first as stated earlier.

what year 200?<br /> the system changed slightly over the years.<br /> have you made sure the vapor seperator is actually getting fuel? any other running symptoms? drain a sample from the vapor seperator and check for water.

hello again<br /> have you done the basics of two stroke tests? compression and spark. verify them first before doing anything else. actually its a basics forALL internal combustion articulated rod desighn engines. its a must.<br /> suck,squeeze bang and blow.<br /> its worked that way since the 1800's and most likly will past the end of the 2000"s.

I had the same problem with my older 1988 200hp and it was the stator.

Wow, thanks for all the responses! I haven't done the compression test, but we've changed the plugs, poured out the filter, I think I'm going to buy a new one today and try it. Apparently the stator has a high end and low end...is that true...

Yep, it's true - it was the high end on mine that died.
