So that's the same manifold I replaced on my 340 cat ETX. (531401HL) They come directly from indmar and it was drop shipped to me.

I ordered mine on 4-26-2021 and it was going for $1225 at www.activewake.com and I used a 10% discount code and got no tax and free shipping.

Looks like it's now backordered on their site and price has gone up to $2109. Ouch. That's a serious price increase.

Lemme guess, you overheated your engine and the internals of the manifold broke and are now allowing water to get through the air passages and fill your cylinder?
