manual oil pump

The manual for the Universal diesel in my Bristol 29.9 says to use a manual pump inserted in the dipstick hole, not the drainplug, when changing the oil. The guy who sold the boat to me told me his manual pump didn't work too well for that purpose. Anyone: is there a brand and model of manual pump that you swear by for this purpose?

We have a fitting in the drain plug hole with a length of hose permanently attached (and capped off) This hose is stowed in the engine compartment so that the end of it is well above the oil sump.
To change the oil we connect on one of those vacuum pump oil reservoirs:
to the hose, pump up the vacuum and the oil runs cleanly into the pump tank. We are pulling off the drain plug, the lowest point on the pan and it's a larger diameter hose than what can fit into the dipstick tube. Works well and there's no handling of oil other than dumping the self contained tank into the recycle tank.

Then for the oil filter I place an oversized plastic bag around it as I spin it off(ours is at an angle), any oil that runs out is captured before it hits the block or the bilge..

Most seem to work well as long as the oil is warm enough, just idling at the dock usually isn't enough, drive around the harbor a little.
