Re: 1993 175HP Ocean Pro shuts down
Welcome Seabytes!!!!!!<br /><br />I have a similar motor. Since you start out okay and you have these problems after running a while, I would look at three things.<br />The easiest is a loose engine cutoff lanyard switch. Make sure the clip is secure and the switch is functioning properly.<br />Next is a fuel restriction. Is the bulb going flat? Does the motor fire but stall when attemting to accelerate? Try a remote fuel tank and different fuel line to rule this out.<br />Finally, and probably the most likely, is a thermal condition that is affecting the electronic ignition system. Carry a timing light and when this occurs, check all 6 cyls for firing.<br />If you let the motor cool for 1/2 hr and it works okay for a short time, my guess is this is the problem.<br />You can troubleshoot the ignition components using the factory manual (powerpack,coils,stator).<br /><br />One other thing, there is a shift switch on the stbd side that cuts out 3 cyls while shifting. If thats sticks, you will be limpin'!. You can simply disconnect it to rule it out.<br /><br />Good luck and let us know what happens!!!
