I recently bought a dipsick pump for changing the oil on my inboard
Indmar engine. The engine manual states " remove the hull or garboard
drain plug and insert QuickDrain through the hull opening. Remove
QuickDrain hose cap and let oil flow into used container".
Can I used the dipstick pump method instead of the recomended method?
What is a quickdrain?
Is the "hull or garboard drainplug" the same as the plus that drains
the water?

The manual suggests that an oil drain hose is hooked up to the bottom of the
engine. If you can use that it woule be preferrable. You may need a
special fittening that goes into it. If you can see down into the bilge
below the engine you should be able to spot the flexible line going from the
oil pan to the drain plug.

You still may be able to use the dipstick pump if you want but I would
measure how much you get out to see if the dipstick tube goes all the way
down into the oil pan. You need to get something close to the capacity of
the engine out. In order for the dipstick pump to work the dipstick tube
has to be a special longer marine one that extends to the bottom of the oil
pan.

Some dipstick pumps also come with a long thin plastic flexible tube that
can be inserted into the dipstick tube for those cases where the dip stick
tube does not go all the way down. My experience is that it is practically
impossible to get oil out through those tiny plastic tubes.

It will help a lot if you get the engine hot as that makes the oil thin and
flow easier.
