I just brought and installed two oil drain kits on my 5.7L Mercruisers. It was basically two right angle brass fittings and a 42" fuel hose that screwed into the right angle fitting. It honestly was the biggest pain in the ass to get under the motor and install it but it was be worth it for the next seasons to come. I'll get a good clean drain from the bottom of the pan rather than pumping it from the dipstick. My locate boating supply said they discontinued them. I brought them for $30 a piece from www.boatsandmotorssunlimited.com. Make sure you pull your plug and check the threads before you purchase the kits.
