1998 Mercury 225 EFI: Excessive Smoke - Moderated
I own a 1998 OUTRAGE 21 [later revealed to have a 1998 Mercury 225 EFI two-stroke motor] I have been doing the regular maintenance every year, that is, plugs, gear oil, filters, water pump, etc. I have never done any major treatment to the engine.

Mar 16, 2010Re: 1998 Mercury 225 EFI Outboard Issues!!! I have had similiar issues. Check these 2 things-Stator and reeds. My issues were at about 1200 rpm to 2000 rpm. Ran fine wot. Replaced reeds and ran 200% better at lower rpms. If you run high rpms you may have some damage to reeds. The stator was giving me problems also.1998 Merc EFI 225 hp overheating. HELP!
