merc 150 start up problems"<br /> Subject: merc 150 efi dies out on start up?<br /> Submitted by spanky (216.106.246.233) on 2/3/2001 <br /><br /> i am hoping someone else has had this problem. i am going broke paying for a diagnosis with no<br /> findings.here are the<br /> symptoms: i start the engine and begin to accelerate the boat onto plane.at about 1800 -2000<br /> rpm the motor dies as if you<br /> shut the key off.i pull shift back to neutral and it starts immediatly.i again advance the throttle<br /> and the same thing happens<br /> again and again and again. this problem does not occur all the time.i have been told that<br /> diagnostically the motor spec's out<br /> 100%.i pay for the labor go out and try to use the boat and it will happen again.does not seem to<br /> be temp related.i have<br /> checked for water in fuel which is not the case, and am at a loss on what to try.i fish offshore<br /> alot in the great lakes and can't<br /> trust this motor at this time.the times this problem goes away or does not occur the engine runs<br /> out a-1 upto full throttle. it has<br /> been suggested that the problem may be in the voltage regulator producing too much current and<br /> then shutting down the high<br /> pressure fuel pump.<br /><br /> any of you motor gurus out there PLEASE HELP.i would like to call on land line if you think you<br /> have a constructive<br /> guess...please post or e-mail me.our hard water is soon to be gone.<br /><br /> thanks,<br /><br /> spanky
