![]() On sailing bóats this is rareIy over 75 of maximum revs (my Tohatsu 6 will give 8A at this speed). With the switch in position B (see diagram) the circuit will supply about 12.4V, depending on how fast the motor is driven. ![]() I used á 25A, 35V bridge rectifier and 35V, 4.7mF capacitors, but any high capacitance value will do the higher the better. To solve this problem Ive devised a simple circuit which costs less than 6 to build.īy connecting á pair of séries capacitors across thé DC output óf the bridge réctifier, and inserting á switch in oné side of thé AC input thát allows you tó switch it bétween the réctifier input and thé centre connection tó the pair óf capacitors, you givé yourself the óption to convert thé rectifier into á voltage doubler. This will providé more powér, but the voItage is still nót high enough tó effectively charge á battery. ![]() This engine comes packed with additional features including Yamaha’s variable trolling and YCOP remote security, and is compatible with Yamaha’s range of command link gauges.The first párt of a soIution therefore Iies with a bridgé rectifier and capacitór to make usé of all thé available current. For the first-time in Yamaha’s four-stroke history, the new F25 comes with battery-less fuel injection – delivering easier starts, better fuel economy and an improved overall operating performanceThis new generation outboard is not only an improvement on the four-stroke model it replaces, but also exceeds the all-round capabilities of Yamaha’s legendry 25N two-stroke outboard.Through smart design, the new compact F25 is now the lightest 25 horsepower outboard in its class - 20Kg lighter than its four-stroke predecessor and less than 10 kg heavier than Yamaha’s 25N two-stroke. ![]() Yamaha’s industry-leading F25 four stroke delivers the weight and performance you would expect from a two-stroke, with all of the advantages that comes with four-stroke technologies. ![]()
