3.0 TKS - 135 HP

Full Mercury factory warranty.

You'll find the 3.0 TKS powering small runabouts, pontoons, commercial fishing boats and everything in-between. That's because this little engine has earned a big reputation for powerful reliability and excellent fuel economy. Its large displacement four-cylinder design makes it a terrific performer at an amazing value. The 3.0 TKS features MerCruiser's exclusive Turn-Key Start (TKS) system. This patented feature eliminates the hassle of starting a cold engine. Simply turn the key - no choke, pumping or priming are required. The entire MerCruiser gas lineup features TKS. No other engine manufacturer can match that.
