After introducing naturally aspirated V-6 outboards in February, Mercury Marine is pulling the sheet off new V-8 outboards that are also not supercharged.
Depending on the model series, the new motors will be available in horsepower ratings ranging from 225 to 300 hp. The 4.6L V8 AMS Verado and 4.6L CMS FourStroke will come in 250 hp and 300 hp ratings. The 4.6L V8 CMS and Pro XS come in 200-, 225-, 250-, and 300-hp versions. For commercial applications, the 4.6L V8 AMS is only available in 300 hp and the CMS SeaPro can be had in 225-, 250-, and 300-hp versions. Also new is the 3.4L V6 CMS Pro XS 175.
The AMS and CMS designations stand for advanced midsection and conventional midsection family. The conventional midsection models are aimed at tournament anglers and performance-minded consumers for whom top speed and acceleration are key. The advanced midsection motors are targeted at more luxury-minded boaters who want increased noise and vibration mitigation. The new motors will use the same mounting brackets and systems as the V6s.
One of the most noteworthy specifications of the new motors is that the FourStroke version weighs 527 pounds, the ProXS checks in at 505 pounds and the Verados weigh 600 pounds. That gives the motors some advantageous power-to-weight ratios.
“Early on in the program, we set very lofty targets for weight on all of the new V6 and V8 variants and to hit these targets, every component had to meet a stringent weight target of its own,” said Mercury Marine president John Pfeifer in an email. “Everything from lightweight cowling materials to our proprietary alloys contributed to the achievement of these aggressive targets.”
