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
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.
