Hey guys, I have 2 525 efi's and had a tach go bad after getting waked, the transom is really low on the boat, I read this can be do to the map getting wet. If so will it correct itself after drying out.
Any input is really appreciated.
Thanks very much

pulll and clean your main harness,,,

Thank you for the reply, are you referring to the main ecm wiring harness at the back of the motor?
Seems weird that the wiring on these motors isn't more "waterproof".

Ten pin harness

Thanks once again
