Ok, so I feel like an idiot even having to ask this. I have a 1988 Bayliner Capri with the OMC 2.3L I/O engine. I just got it and wanted to do an oil change and new plugs. Went and got all the stuff and ran boat for about three minutes on muffs. Pulled out dipstick which shows it has plenty of oil in it. I threw my electric pump down in dipstick hole and began to pump. It will not pull anything out!!! It is working I even tried on my new oil and it sucked it out of quart. There is oil all over line when I pull it out also. HELP! Can I not pump oil out with pump on this? Also, what are my other options. THANKS so much everyone. I feel like a complete newb with this dumb of a question.
