Both boats share a closely matched power ceiling — 150 hp for the Sylvan Avenger 1800 SC 2006 and 150 hp for the Sylvan Expedition Sport 1800 DC 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
