For 2009 the 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 1977 Aggressor EXP. Along with the 1875 and 1877 Aggressor EXP models, these new boats offer to the discriminating angler just about every eature 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 on the 1875 and 1877, and to 200 hp on the 1977.
