Aggressor EXP line remains unchanged. The 1977 joins the EXP lineup with even more room and features. Innovative features like snap-in carpeting and optional second livewells are available on the Aggressor EXP. These boats offer to the discriminating angler just about every feature and option choice available in the industry. From our incredibly strong twin hull featuring a new full 2" thick 25" tall transom to our plush pedestal seats, everything is pro-level quality. Additionally, our engine horsepower ratings have increased from 150 hp to 175 hp.
