I have a Suzuki 200 Hp, it´s work great at idle, but when it´s running in low speed go great, at high speed go great. but at mid speed go off.<br /><br />I found the problem, I belive that is the fuel, I mean the motor need more flow of fuel, The motor at high speed makes ups and downs too, If I check the transparent filter at this moment, it is empty. If one frind is seated at back seat pumping, the filter is load all time, and the motor goes great. <br /><br />I changed the water separator, the fuel filter, cleaned the tanks, cheked the lines, all is Ok.<br /><br />I made a test, I eliminate all the filters, and the fuel flow is great and it work great, but if I reconect the filters the problem come again, I have an hipotesys now, I wanna know if it make sense!!! The long of the hose between filters and the motor, if it is so short can stop the flow?<br /><br />It can be all the problem?<br /><br />Best regards and keep boating...
