Now, that’s a REAL outboard…350 HP!!

I just got a serious dose of “Small Motor Complex” when I saw this the other day: Yamaha has introduced an outboard the size of Delaware to it’s lineup…a massive, 350 HP four-stroke.

This beast is a 5.3-liter V8 and weighs a “mere” 804 pounds. According to Yamaha execs, it should be a good choice for boats all the way up to 40 feet in length….though I’m guessing the bass guys are already trying to figure out how to reinforce their transoms to fit it.

For all you wrenchers out there, the big boy’s design features a 60-degree V8 with 32 valves (four valves per cylinder) and double overhead cams. It uses variable camshaft timing to optimize the engine’s torque at low and mid-range rpm. With sequential, multi-point fuel injection, it has eight long intake tracks in the induction system to optimize power. In addition, it features In-Bank Exhaust with Dual Power Surge Chambers, a system that relieves pressure in the exhaust ports.

Translation: Big motor go faaaaasssssssssssst!
