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!!
Thanks again!!
