question on oil changing

I'm full of questions today. I just got my Cobalt 190 boat. It has a brand new engine in it ( Ford 302 ) and I will soon be changing to a synthetic oil. I use Mobil One in all my vehicles. What device do you use to drain the oil ? And where can I get this ?

I suck mine through the dipstick. Just Google oil change pumps. Sorry. Mine was like 25 bucks and have had it for about 3 years and leaks so I'll need a new one soon. 2 minutes and the oil is out. I Have a 12v pump others use a vacuum type. They both work
Congrats on the 190 best boat Cobalt every built!

Thank you for that info. I wasn't sure they made a tube that would go into something as small as the dipstick hole. Also wasn't sure if the tube would reach to the bottom of the pan. Its' too bad the manufacturers don't put a valve right on the oil pan where you could hook up a suction hose. I did that on my riding lawnmower and it sure takes the pain out of oil changes. Thanks for the comment on the 190. Sounds like I finally did things right :-)

You can buy a drain hose that connects to your pan. It replaces the drain bolt. It has a cap on it so you can either shove it out your drain plug or suck the oil directly out of it, whatever is easier.

Here is an example of one.

You just have to purchase the correct one that matches to the thread of your current drain plug.

You of course will need a way to drain the engine the first time before adding this drain hose.

What year is your boat? If it has a Ford, the newest it could be is around 1998 because that is when Ford left the marine market. Volvo or Merc? The reason I ask is because the Volvo, even older Volvos, have the dipstick tube already going to the drain hole of the pan so you just use a pump with a garden hose fitting.

I had that on my sea ray and really liked it. Not much access on my 220 to retrofit it.

I use a Moeller hand pump. It works pretty darn good.

Moeller pumps are good.

I use one like this. Especially nice when you have 9 qts like my old 7.4L had.

Mine has the garden hose fitting. Sending a skinny tube down the dipstick makes things really slow.

Honestly I had one of these on my 350 mag in my crownline. I hated it. Used it 1 time after that I used the dipstick method. Plus if that drain plug has never been out they are a bitch to get out sometimes.
So this is the pump I bought on a budget. Worked great for what it is.
I used a washer hose to connect to my dipstick. Screwed right to it. Works great. Don't take this the wrong way but if you can get a picture of your dipstick tube that will help to see if that method will work. It might be a bit too old though.

The biggest tip to changing oil is to make sure the oil is plenty warm to help it flow out. Don't do it cold! Same with the gear lube.

The boat is a 1996 Cobalt 190. The engine is a Volvo-Penta but uses a 302 Ford block . I really haven't had time to go over this boat as I just purchased it. Just trying to learn all I can before the ice gets off the lake and I can try her out. The engine has a total of 3 hours since new so an oil change will be coming up soon.

Then you have the garden hose fitting on top of the dipstick. That dipstick tube already goes down to the drain plug of the pan.

Just buy a pump with the garden hose fitting on it. No need for that hose I posted earlier.

You can get something as simple as this:
http://www.marineengine.com/products/ac ... in=2214877

or get one of the pumps where you pump to get a vacuum

or one like mine with the 5 gallon pail with the pump sitting on top of it.

Just so you know, you have one of the first years of the Volvo/OMC joint venture drives. You can look up parts via either a Volvo or OMC lookup. Your model number will include characters like HU NC or LK...those numbers indicate the year of the drive/motor.

You have carb or fuel injection?

I know it's a new engine but see if they have this on tune harmonic balancer. It's where the impeller is. I take it you have a SX drive? Single prop.
I rather be safe then sorry.

Let me say I hate changing oil on a cold engine . Now let’s add cold oil and and reverse gravity.
I had a Twin with pull thru drain plugs like Bruce mentioned.
So nice to pull the drain plu and tug the hose out attached by the plug.
But it’s for ever and installing one requires someone small.

Tip for the old school vacuum pump.
If you can run the engine on muffs for 5 minutes the oil will be warm and suck out easy.

Here’s what I use on the dipstick fitting,and with the other adapters it works for everything . Cold or hot.

Plus it designed to hold oil and stay spill free.

Keep it simple.

The engine does have that harmonic balancer. The stern drive unit is the SX. The engine is fuel injected. Thanks to all you folks for helping me understand what I have here and how best to handle oil changes etc. I have to be able to do all this stuff myself because there isn't anyone around here to help. But I can handle it. I'm only 87 years old.

I always change after my last boating of the year. Getting out hot oil is way easier. Any update on your search for a new sleigh?

Ongoing but im being picky going back to a single. Now a 220s like yours with a 8.2HO would be awesome :D but a 272-276-maybe R7 with HO power ( I may get in trouble for that one :lol: )
