I have a Lazer HP, 44 with 19 Kaw. Changing the oil is not the easiest thing without spilling oil all over the engine deck. Is it all right to use one of those syphoning contraptions that stick a long skinny hose down the oil dipstick hole and remove oil that way? This method sure is a lot easier, but I'm concerned I won't be able to adequately drain all the oil. Thanks for your help.
