Anither Kohler 5e water ingestion

[DaleM]

Alex,

Thanks - I get that. I also mentioned that I'm pretty sure (as in 97%) what the cause of the water ingestion was and was holding back on that piece as it was an accident (not as a result of my doing) and something that will/can be avoided easily in the future. I've been in contact with the service department at our marina who agrees that what took place could have caused the situation. Even rough seas could cause it from what I've been told by them and read. That said.... I'm simply looking at options (preventative measures) to lessen the chances of a future occurrence. I don't doubt the minds at SeaRay but if there is or "was" an exhaust cover that fits why not investigate it? I don't necessarily agree with "then SR would install it on every single boat" because as with many things, things sometimes get missed in assembly. I've witnessed it first hand with different areas on SRs. It's not intentional, it's just the nature of the beast. Hence, my general question about the exhaust. As a general practice I'll be closing the seacock when not in use which is good feedback - preventative measures. As always, I do appreciate the information that's been gained from this group!

I thought I'd share an update to this thread and the comments mentioned by Alex F. I recently splashed the boat and part of my commissioning process was to pull the impeller. This particular impeller had two seasons on it. When it was pulled last week, three vanes were broken/missing. I did back flush the system in attempt to recover the broken pieces but was unable to.

Based on the missing pieces, I can see where the water could push past the impeller if there are vanes missing with the seacock open while on plane. If all the vanes are in place then you're creating a "seal" for lack of a better word between the intake side of the pump and the outlet to the exchanger.

Anyway -that's what I saw.
