If you have the engines out, just go to a dipstick setup that goes to the bottom of the pan like this. It has a garden hose fitting at the top of the tube to hook up to a pump. These are Volvo/Innovations, and all the parts are available through Volvo Penta. No tees, quick-disconnects or extra hoses.

I have some that I got when I bought the 525SC's years ago, never used them, but I think they were Aeroquip (sp?). These were some real high end chit, I will look and see if I can find them and if they have #'s on them. Need to find them anyway cause I'm going to move the Merc hoses up to the front of the motors so my pump will pick up all the oil.

The other thing that would work would be the hydraulic connectors for a snow plow. Any plow dealer should have them in stock.

I found the drain hoses at a local boating supply store.....about $25 each. Pull the drain plugs, hoses attached and come right out with them. Twist them open with a wrench and set the open ends in a 5 gallon bucket. Close and refill (+ new filter) the next day.

Dave I went to a place here called Mississippi rubber,they do hydraulic hose and fittings, It has the male end on the hose and the female on the pump hose, they have them in steel lot cheaper,but i like polishing the brass out.I think they were 15.00 for the female 4 years ago

Ill get a close up picture tonight.there in the garage still on stands.
