Merc 90HP Outboard Steam out of Tell-tale

[jblaloc1]

Thanks in advance. I recently changed the water pump on my 2008 Mercury 4Stroke EFI 90hp. Think it all went well, solid stream at all cruising speeds, and the water coming out is warm/cool to touch. Recently I have noticed after running WOT and coming off plane there is steam coming out of the tell-tale for a moment then goes away-have also noticed a slight amount coming from under the cowling. Thinking my engine is mounted too low, and pushing water up into the cowling. Could this be causing the steam issue or am I totally off base, and need my water pump checked out ASAP? There are no alarms and the stream is solid.

Thanks again!!

You mean steam instead of water or steam coming off the water out of tell tale ? One is fine and one isn’t

Steam coming off the water coming out of the tell tale.
