2011 WATER PRESSURE CHART
This chart lists typical water pressure readings for 2011 model outboards for boat speeds up to 50 mph (80 kph/43 knots) and is provided
as a general guide for use when troubleshooting over-heating or over-cooling issues.
Water pressure readings can vary depending on water inlet screen type, hull design, set up, and operating conditions.
