A quick look at some of the top motors available in today's marketplace
By Gary Lewis
Honda BF115 Honda Marine's BF115 is derived from the inline 4-cylinder 2.4 liter dual overhead cam powerplant used in Honda's popular Accord. Holeshot and acceleration are dramatically improved via the use of Honda Marine's exclusive ignition system, which advances ignition spark timing to within one degree of the knock limit during hammer down acceleration. At that point, the Engine Control Module steps in to increase injector timing, creating a more potent air-fuel mixture. In fact, the ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and fuel efficiency. Specifically, the BF115 reduces fuel consumption by 19 percent over the previous model. The new BF115 is lighter than its predecessor. A lightweight engine cover and a highly rigid air intake manifold, mated with a chain driven camshaft, help to reduce total engine weight. marine.honda.com .

Yamaha Four-Stoke F6 Portable Twenty-three pounds lighter than its predecessor, the new Yamaha F6 is easier than ever to handle and install. Yamaha achieved the outboard's weight reduction by switching to a lighter, single-cylinder powerhead design. (The former F6 was a two-cylinder.) In order to get smooth operation from the powerhead, engineers employed a balanced crankshaft that counters the weight of the piston and connecting rod. That means there is little vibration throughout the rpm range. The F6/F4 powerhead uses a wet sump, pressurized oil system to facilitate complete lubrication under all operating conditions. CDI ignition with Auto Timing Control and an automatic decompression device helps assure easy starts, while a twin fuel filter system with in-tank water trap furthers proper filtration. Other built-in convenience features include 180-degree steering, a counter-balanced, low-vibration tiller handle and angled fuel-filler opening to help reduce the possibility of fuel spills. yamahaoutboards.com .
