IF your vessel is fitted with a water
lift muffler it's well advised to PULL
cooling water from a bucket that is kept topped up with water from a garden hose.
cooling water">Engine cooling water flow is dependent on engine
RPM so make sure the garden hose can keep the bucket topped up.
Direct connection of a garden hose to the engine intake hose could very well ruin your engine.
When an engine intake is supplied with pressurized water it is likely to over supply the engine with water whereby the water
lift muffler becomes overfilled and water backflows into the engine.
'City' pressurized water supplied by a garden hose WILL push though a typical
Jabsco raw
water pump fitted even when the engine is not running. Even a small amount of leakage past the impeller could fill the water lift muffler causing the backflow into the engine scenario.
2). Conversely, the garden hose directly connected to the engine raw
water pump might not supply enough water to the running engine and the engine could overheat. Again, proper cooling water flow is dependent on
RPM. Better to use a bucket supplied with lots of water so you can
monitor the situation.
If you have saildrives you can test run your engines by using a barrel full of water to submerse the drive leg, but again be sure to
monitor the water level in the barrel as your reved up engine might use more water than a garden hose can supply. I've done this in the past and was surprised how much water moves through the cooling system at higher revs.
