Newbie here. Bought a 2002 38zx.

Wondering what water sperators do you guys recommend for my 500 efi's (Ac Delco?) and what are you using to extract the oil?

Thanks,
Chris

Welcome.

Buy the Mercury/Quicksilver Fuel/Water separators from a Mercury Dealer.

As for oil changes, also purchase the Mercury kit to add to the bottom of your oil pans, that have a hose permanently attached to the drain hole. Extend the hose out your bilge plugs and drain this way. MUCH better that slurping it out the dipstick; as this leaves roughly a quart of dirty oil in the pan each time you change the oil. Yuck!

Water separater - Merc part # 35-802893T - probably about $10 per filter from a Marina, at least that is the going rate around here.

I agree with Sydwayz, if you can set up to drain out the back you will get all the oil out.

Otherwise buy yourself a pump that sucks it out the dipstick. You can get manual or electric, my opinion is the electric ones work much better. On the engines I have used them and they got ALMOST all of the oil out, all but a couple ounces. But I have friends that have left a quart behind.

if you suck out the oil , tilt the boat in the direction of where the hose bottoms out in the pan[floorjack on trailer]through the dip stick tube, then you can get almost all the oil out. I replacede my filter mounts and use the high flow billet Teague models with the big fram fuel /water filters
