I have a 2005 2575RL I/O with a 5.7L Volvo Penta engine. On the starboard side of the engine is a long vertical tube with a garden hose threaded end and a cap that I was told was used for flushing/winterizing the engine. Am I able to winterize it by first placing a funnel in this tube, having water from my garden hose go into it, turn the engine on, and then after ensuring the engine temp is up (and thus the thermostat open) dump 2 gallon jugs of RV antifreeze in it and then just before the 2nd gallon has emptied and is down the funnel, turn the engine off and that sucker is winterized? This is exactly how I winterize the car engine in my ski boat (except that engine has a carburetor so I also fog that right at the end of the 2nd jug of antifreeze but the Bennington engine is fuel injected of course). I would GREATLY appreciate a quick response as I have a major family emergency with my premature twin babies but I have to get my boat pulled out of the water tomorrow morning and winterized. Thanks very much!
