Neutral switch, droping RPM?

[Daniel Beckman]

This is my prob.<br />92 john fastrike 175 v6<br /><br />It drops power exact at 4800 rpm. Im turn it back to idle and it works perfect up to 4800 again.<br />When it have drop the power it kicks up and down with short rpm peaks trying to get power again.<br /><br />Now my marina guys have tried the boat on the lake and tracked down the prob.<br /><br />They say if they disconnect the electri neutral switch on the side of the engine the engine will run perfect without any problem.<br />But then they cant shut down the engine with the key (it just drop a little rpm's when they do that)<br /><br />But they are no rude or john experts so they say they have to get someone the knows more about the system.<br /><br />I know this is the place to find the experts.<br />Anyone knows what can cause this, is it the switch itselfs or can it be a combination of several faults?

The little switch on the side of the engine, connected to the shift linkage is not a neutral switch. The switch is a shift switch and may be shorted or the wires shorted. Check the coils for arcing to metal plate between the power pack and the coil. The plate will have a burnt spot on it.
