Changed head gasket on df250 . Ran up system and all o.k Launched boat and as soon as i went over 3000 revs engine went into alarm . Fault 23 and 52 constantly flashing . Is it just a case of resetting ECM and if so how do i do this?

It,s gonna keep flashing until ther are fixed.
Why did u replace head gaskets?
Do u have analog guage ?

Replaced head gasket because it neede to be replaced . Damage because it wasn't winterised properly . Found loose jackplug that seemed to rectify slight vibration issues . Took boat for a run and as you said alarms cancelled themselves . Now i have developed another problem . The engine only revs to 4000 revs . Fuel system o.k and no alarms showing up . Any ideas ?
