Suzuki Marine has in­tro­duced its big­gest out­board — the 350-hp DF350A 4-stroke. The en­gine has a V-6 pow­er­head, a high-per­for­mance 12-to-1 com­pres­sion ra­tio and “con­tra-ro­tat­ing” dual props, among other fea­tures.

“We have watched with great in­ter­est as boats have got­ten big­ger, es­pe­cially in the cen­ter con­sole mar­ket,” Ya­suharu Osawa, ex­ec­u­tive gen­eral man­ager for Suzuki Mo­tor Corp., states in a press re­lease. “Not only that, but we’ve seen an in­creas­ing pref­er­ence for out­boards on all kinds of boats that used to be ex­clu­sively stern­drive or in­board.”

The com­pres­sion ra­tio is the high­est ever uti­lized in an out­board, ac­cord­ing to Suzuki, pro­duc­ing 80 horses per liter. A di­rect in­take sys­tem with a dual-lou­ver setup di­verts mi­cro­scopic water mol­e­cules away from the in­take flow. Dual fuel in­jec­tors in each cylin­der head help boost out­put.

The counter- ro­tat­ing props have twice the blade area and pro­vide more “grip” in the water, which in­creases hole shot per­for­mance and re­duces time to plane, ac­cord­ing to Suzuki. The setup also takes ad­van­tage of the pow­er­head’s in­creased torque.

The DF350A is avail­able in 25- and 30- inch shaft lengths, weigh­ing 727 and 747 pounds, re­spec­tively. Suzuki Mo­tor of Amer­ica, Brea, Cal­i­for­nia. (714) 5721490. suzuki­ma­rine.com
