Please can someone advise me on the following? Should the engine pump out cooling water as soon as it is fired up? I ran my Evinrude 40hp BE40ELCR yesterday and noted several seconds say 10/15 before water appeared and as before was pumping strong,I then noticed that the bucket containing the cooling water level was only just up to the top hole ie; where water enters leg, I stopped engine to fill bucket, blew down coolant pipe (bubbles in water) but was surprised when I couldn't suck water up coolant pipe! why was that? Is there some kind of thermostat in there to let temp come up before pumping straight away?thanks again J.B.D.
