The owners manual is not much help. So I thought I would post what I have gathered and see if anyone has suggestions or improvements. The picture of the 5 critical drain plug points has been previously posted in pdf format.

Add Stabil fuel stabilizer to gas tank and fill tank

Remove 2 hull drain plugs and place in ziploc bag, tape to steering wheel

Pump out all ballast

Attach hose to water intake and run engine to operating temperature / 160 degrees

Drain oil, replace oil filter with Motorcraft FL-820 or Wix 51372

Fill oil with Semi Synthetic 5W-30 - 8 quarts

Remove 5 drain plugs from heat exchanger , manifolds and transmission ( see picture)

Clean and drain lake water strainer if equipped ( was an option)

Remove spark plugs and fog each cylinder with fogging oil, crank engine to spread fogging oil

Detach hoses from ballast pumps, pour in RV antifreeze, cycle pump to insure it runs through

Detach and remove ballast bags, add 1/4 cup bleach and slosh around

Plug in on board battery charger or remove a batteries and place on trickle charger



Every other year ? ( I have the Indmar V Drive unit )

Drain and refill V drive (yellow dipstick)and transmission ( red dipstick). I believe these fluids need to be sucked out with a vacuum pump and a small tube.

Trans takes 2.3 qts Indmar ATF 872006 ( Can use Dextron 6 synthetic)
V-Drive takes 1.25 qts Indmar Synthetic 50 Transmission oil 872009 ( can use Mobil Delvac 50 synthetiic transmission oil)

Replace lake water impeller


I welcome and constructive comments. Thank you.
I had thought I removed 5 but realized today that I only removed 4. I have the 2 blue plastic wing nut looking plugs. One is from the manifold crossover. The 2nd is from the tube between the raw water pump and transmission cooler. The 3rd is the drain plug/anode from the heat exchanger. The 4th is the plug/ anode on the rear of the V drive.
Which plug am I missing? My manual only indicates 4 plugs from my understanding. Thanks for the help!
