- 150 4-stroke Mercury outboard
I did several searches after reading and re-reading the Mercury 4-stroke 150hp Owners Manual and haven’t found an answer so, thought I’d post it here:
Q - When running the motor on the hard (on trailer and in order to warm the engine oil up for an oil change (in Neutral, of course) and after hooking a garden hose up the nifty hose connector they now include on the Mercury 4-stroke outboards, DOES IT MATTER WHETHER YOU START INJECTING WATER BEFORE THE ENGINE IS STARTED *OR* SHOULD THE ENGINE BE RUNNING BEFORE YOU TURN THE WATER HOSE?
(I ask as, with jet skis, it is absolutely CRITICAL that the engine be running BEFORE you ever start any water going into the machine.
When I go to warm up the engine oil on our outboard; however, either the engine will be running for a few seconds before I can hop off the boat and jog over to where the water spigot is OR the water will be running into the motors before I can clamber aboard to start the engine (in Nuetral, of course).
I just need to know which to start first, the engine or the water.
Thanks (d*mn, all this winterization talk is so d*mn depressing! )
