Bought last Spring from dealer and replaced impellors on water pump after being dry started by wife(her boat). Runs fine now except alarm code 5-1. Ideas? Something I can do myself or take back to dealer?

code 5-1 is : V V T Advance - stbd

Spoke to my mechanic: he said my alarm was actually a 1-5 which implies a weak water pump. Opnions, please.

Tech just called. Now that he has replaced the water pump, he says it is the sensor. Waiting for it to be delivered.

code 1-5 is exhaust manifold temp sensor.if you are getting this code and the engine is not hot its the sensor. if it is hot its not the sensor,might waterpump ,pressure relief ,
