Water pump?

I put muffs on low water pressure but no water going through the boat and my alarm sounded, I shut the boat off after about 1 minute , could I have over heated it and does this sound like an engine water  pump  issue or a lower unit pump issue  and will both be fried now??

    How low of water pressure did you use? I usually give it a decent amount of pressure, the muffs aren’t sealed tight and will release excess pressure when the engine isn’t running.

    Bravo 3 drive when I run it on the muffs I put a piece of duct tape on the cone to cover the hole in front otherwise the water won’t pick up or run it in a big plastic tub

    I don’t have the front hole but I use my hands to hold the muffs tight over the drive intakes until I get decent flow and then can let go

    Ras me too, I make sure to close the thru hull valve when running on muffs, otherwise it just comes right out the thru Hull

    I have the same problem when i was winterizing. Alarm was going crazy. i stop it right away. how was your engine. I did replace my water pump, I found out that water pump starts burning and has some missing empeller blade. now im worry for the spring. what if I cannot find the missinf rubber impeller it could clug my cooling line. hopefully its gonna be there by the thermostst when i open. i will keep you all posted.

    most likely will blow it right out but do check...it only takes a few seconds...if there is another thru hull that can leak the slightest bit your in trouble...
