Have a Mercury 125 2002 O/B 2 stroke - anyone own one of these? Are they good motors?

Answer 1

Ok, a 2002 Mercury two stroke in Oil Injected.  You don't need to mix the oil and gas like the gentleman with the Mariner.  Also, this motor is what Mercury calls a "two plus two" motor.  This means when you drop below 1800 rpm's the motor drops to two cylinders (it's a 4 cylinder engine).  This is great if you want to "troll" for fish or just to go slow.  Now the down side is that there is a SLIGHT delay inbetween going from two to four cylinders.  It's not huge but you will notice it a little when taking off.  They have had this technology since the late 80's on this motor so don't worry about dependability.

How do I know?  I have been around boats for 28 years, and have sold Mercury's and been to their training every year since 2000.

Answer 2

Merc's rock! Super easy to work on, reliable and stand up to the abuse quite well. Just make sure you change the impeller every year or two.

Answer 3

I have a 115 mercury mariner 2 stroke on a ski boat. it ran wonderful for the first 25 years then the brushes on the starter gave us some trouble. Its only a hassle to mix oil and gas every time to fill up.
