2004 Merc 60 hp- 4stk- EFI less than 10 hrs on the engine. At start up, there was water coming from the water pump indicator hole. After 10 minutes of operation at low speed I notice there was no water coming from the indicator hole. I stopped the engine and checked the intake for obstruction, there was none. Restarted the engine and still there was no water coming from the hole. The trolling motor got me to the dock, and I plan to take it to the dealer in the morning.<br /><br />I did have too run for a short distance with the engine trimmed up through a shallow muddy area, but the water intake was never out of the water. I received no warning indicators from the warning system, and the engine started and seemed to run fine at low power. <br /><br />The question By running for possible 10 minutes without water to the engine, what should I be prepared for at the dealer ?
. Tell your dealer what happened. Have him run a compression and leakdown test to make sure that there was no harm done to the powerhead. <br /><br />It's the old pay me now or pay me later scenario. Being a 2004 engine I would want to know that it is alright. A compression and leakdown tests should only take about an hour and are well worth an hour of the shops time. <br /><br />There may not be anything wrong if you didn't get an alarm, you may simply have a plugged telltale hose. But in my opinion (as a service manager) have them do the basic diagnostics. An ounce of prevention is worth far more than a pound of cure in this case.<br /><br />Good luck and keep us posted!
