Engine flushing

[thiede]

I recently had a soft grounding. I believe the engine ingested some mud which plugged up the cooling circuit of my emm causing it to fail. My question is this: Is there a special flushing procedure that I should use other than relying on the water pump to clean up the cooling passages? Would adding a detergent to the tank be of any use? I don't want the rebuilt emm to fail prematurely because of reduced cooling flows.

Re: Engine flushing

We might be able to send some input your way but you forgot to tell us anything about the engine - make/hp/year would help - - oh and forget the detergent. Did it overheat?

Re: Engine flushing

2000 225 Ficht 330 hours. After the grounding I noticed a reduced flow in the pee stream. I continued to run it the next day because my water pressure seemed ok. After about an hour at trolling speed the horn went off and the check engine light came on. I tried to "milk it" home but it went into slow mode then quit. The mechanic said it didn't throw any codes. The emm technician (DFI) said it had several instances of overheating. Like I posted initially I'm concerned about reduced coolant flows. I will check the flow from the vapor separator but I'm also concerned about blockages in other passages.
