Check Engine light at high speed

[USSDefiant]

Begin Transmission Command Defiant

Hey guys :wavey: , I got the boat out after changing the impellar and starter. everything seemed fine but the check engine light would come on above 32 mph. after shutdown and restart no light, unless you went over 32mph again. anyone have a thought? I also noticed the oil pressure running a little high( almost 80psi at 30mph)

A code reader(even the cheap little two prong metal one) will let you see what codes are stored in the ECM. If the light is going on, somehow find out what's happening before taking it out again. A bad weekend without the boat is better than toasting the motor.
