MerCruiser 4.3 TKS - 190 HP

This popular model powers everything from family runabouts to houseboats. Its smooth power delivery and excellent fuel economy make it a great choice for boaters who want lots of torque without the extra weight or size of a V-8. The 4.3 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 Turn Key Starting. No other engine manufacturer can match that.
