- 2 Merc 8.1S Horizon V-Drives
Hi all. One month owner with 30 good hours until this simultaneous starboard engine (8.1S Horizon) SmartCraft SEA PUMP CKT HI alarm, accompanied by a water drain drip (180/min) which only drips when the engine is off. H2O Press reading was pegged (43.4 PSI) with all other indications normal. Replaced the raw pump pressure sensor, cured the alarm. Drain still drips, and slows as line loses pressure, down to 10/min. With engine on, no drain drip. Two questions: Did the PUMP alarm actuate the drain, or are these two events related in some other way, like by ingesting something? (The two failures are 18 inches apart in the same raw water system.) Is the drain drip fixable or do I need to replace the part? Note: Everywhere I’ve looked, the starboard drain replacement part (863716A2) was "no longer available," while the port engine part is (863717A2). Many thanks, Mac
