Best set up for block drains

I like to drain the block for the winter, but the plugs are a mofo to get to with all of the hoses around that area. I bought the plugs with the wings on it but they didn’t help matters any. Has anyone put extension hoses on them to a port valve of some sort? Surely there’s a decent system of some sort?

I'd tap the drain plug holes out to the next size and then run the extension hose.then you can use welding wire to open up any blockage w/ ease.

I made some tools for the shop to help with the Mercruiser blue plastic wingnut drain plugs, I found them a real PITA. we have a few hand held ones and one on a flexible shaft. We always use dialectic on the thread when we reinstall them which helps for the next year.

I installed these on our old Top Gun. It greatly cut down winterizing time!! 3 hours of playing twister to ~15 minutes for both engines. I was worried about them falling due to vibration but never observed an issue...

did you leave them as they were after you installed the valves or did you add extensions? I like the idea. Should’ve done it when the motors were out.

I have installed prob at least 700 of these and always have about 40 on hand if this helps whomever. Very easy to install.https://cimg8.ibsrv.net/gimg/www.off...189ceb1812.jpg

Do these thread into the fitting in place of the blue plugs, or does the brass fitting need removed from block and these thread into the block?

They install directly in the block,

Edit: they appear to be about 1.5 inches long, so about the same length as the brass adapter and blue plug together

When I refresh motors in a couple years, these will be added. No way I can do it with engines in boat.
