Understanding Evinrude Water Cooling And Thermostat Visualizing The Understanding how evinrude watercooling and thermostat work.this is a 1990's evinrude 40hp outboard. marineengine parts johnson evinrude parts . Sep 19, 2011. #10. re: trying to understand the water flow through a crossflow v4. i would guess its a vapor air bleed which prevents hot spots. i clean them out with sharpened steel rod in a drill. a drill bit can also be used, but if it grabs and breaks off, its in a bad place so i use a sharpened welding rod.
Service Manual Evinrude E Tec 40 60 Hp Cooling System Hose Routing And Sep 20, 2016. #1. 1968 6hp johnson cd 25a cooling system water flows. i could not find a water flow diagram that really shows the water as it flows through the engine, other than an undetailed drawing in the service manual (see it below), therefore i decided to post here the water flows as i saw it from disassembling the cylinder head and the. Rubber water dams (10) in the cylinder block (6) are used to direct the flow of water to cool the cylinders. after cooling water completes the circuit around the top of the cylinder bores, it enters the bottom of the cylinder head (11). water flow then fills the cylinder head until it reaches the thermostats (12 & 13). if the thermostats are. Water flows through the block to the adapter housing and then out of the outboard. at low speed, the pressure valve is against the seat and the thermostats are closed. warm water from the top of the cylinder block gradually migrates to the thermostat pocket at the top of each cylinder head. water movement is the result of water “bleeding.

A pressure relief valve is used to control water flow and operating temperature at higher speeds (above approximately 2500 rpm 21 psi). pres sure relief valve activates or “blows off the seat” as water pressure increases. spring tension is used to set the “blow off” pressure. overheating: a restricted or faulty valve typically results.
