Draining your oil
 

So I've been sucking the oil out of my boats for years through the dipstick, and I've never liked it. I'd like to drain it out of the pan and run it out of the transom drain. Can anyone recommend a reliable valve that I can install on the pan with a "nipple" or similar fitting that I could reach down and attach a hose small enough to route out the transom???

This is what I plan on using:

The 20baja outlaw has a sweat set up, when you pull the drain plug far enough, the hose from the pan is connected to it. Just remove the fitting and out comes the oil, ALL OF It!

Do a search. It's been discussed on here many, many times. Mercury makes a kit for it.

I just pulled the drain plugs, attached a 90* fitting put some hose on it, ran it up front witha small brass plug/cleanout on the end of the hose. When it's oil change time I just hook a drill pump up to it and it pumps it out in about 3 minutes.

The only thing that sucked was that it sucked shimmying under the engines to put the fitting in.

Perfect, exactly what I'm looking for.

I have Fumoto drain valves in everything except the boat, haven't got that far yet. They work great as long as the oil is warm, otherwise it's a slow drain. Positive lock when closed too! They do have a model with a nipple on it. I put a vaccuum cap on it to keep it clean.

This is what I just put in my boat a little slow, but faster than siphon and a whole lot easier. Pull the drain plug. pull out the hose, let it drain in pan and walk away.

I put these kits in my 382. I'd get home from the ramp, park in the garage, pull those hoses and open them into a bucket. Monday evening after dinner I'd go change the filter and re-fill with oil (after closing those hoses)
