Trouble changing my oil

I'm changing the oil on my super sport. I have the pump, hooked it up to the dip stick and started pumping... after several min. of pumping nothing happened. This is with a hand pump. Also a week ago or so I tried doing the same thing with a pump using a drill, after wearing down two batteries same thing... I had nothing. Is there something with nautique I don't know about when it comes to changing oil. Any thing would help I really don't want to go to the dealer to get it done.

thanks Blair

First off the oil through the dip stick is probably the most time consuming way of pumping out oil due to the small diameter. Also are you getting the boat up to normal operating temp before attempting to pump?

Do you have an oil drain tube running from your oil pan? If so this is meant for removing oil.

you need to have the crankcase vented. Take off the oil fill cap. This will vent the crankcase and allow you to pump out. .
Like DEEP said above the small diameter of the tube the way you are doing it will take forever. It can get clogged or gummed up with thick oil, and sometimes they do not reach to the bottom of the pan.

Good Luck

I pump through the dipstick everytime on my Mercruiser. Oil has to be warm, I usually do it when I return from the lake (15 minutes from ramp). I have a battery operated pump with a tube that goes through the dipstick hole and extends to the bottom of the pan. Takes about 15 minutes to drain the oil.

If you just hooked the hose to the top of the dip stick tube, you aren't getting down into the oil and you're just sucking air. Put a small hose down the dipstick hole to the bottom of the oil pan.

What year is your SS? The GT40 has the oil pan drain hose. Take a look around the motor and make sure that you dont have the hose. It is much easier than the dip stick method.

It's not time consuming at all (if done right) and half as messy. They've been doing it that way for years on heavy equipment so i'm sure it works fine on an inboard.

Make sure you clamp the tube before you start pumping it to create pressure, once the pump gets hard(about 15 strokes)just release the clamp and it should start draining. You may have to clamp it off and prime it again if it loses suction & the oil must be warm.

Thanks for all your input after I posted this Sunday. I went back out to the boat and looked the engine over. This time I found the found the oil pan drain hose. 10 mins later I was done. Thanks again
