Hello guys,<br />I looked for this topic, but i didn't found the answer.<br /><br />I try to explane my problem. Sorry, my english is not so good...<br /><br />I have a Yamaha F100 four stroke from 1999. The boat is a normal console boat (5 meter, 470 kilogram). The prop is a 19 pitch.<br /><br />When i give (from stationair trottle in forward direction) in one time full trottle, the motor has a little dip (1 second or so). It seems it has too little fuel. That is the only dip in the rpm range. When the nose is down, no problem anymore. Normaly i give first half trottle, then full, also no problem. Only when the motor from 1000 rpm to full trottle.<br /><br />I think it is better when i give quite trottle than trottle in one move, but maybe i can fix this problem easily.<br /><br />Thanks and greetings from the Netherlands,<br /><br />Mish
