175 Merc EFI alrm

the easy thing to check is the oil reservoir under the cow. sometimes this gets low and the float will move around when up on plain. also the float can stick. this is the most common problem with these engines. i have seen people spend alot of money for a simple problem. check this out and see if it will fix it.

there is a sensor on the line in the oil tank in the boat these get gummed up & dirty sometimes especially if you run it low on oil. unscrew this it from the tank take it out & wash it off with gas .its a stem with ascreen on the end. i've had this happen to me couple of times once on 150 merc xr4 & a merc 225 efi. hope this helps.
