We just purchased a 24' pontoon which has a 2005 40hp EFI 40-Cyl Bigfoot, sn 1B005337.

I've got a fair amount of experience with 2-strokes, but this is my first 4-stroke. I don't know the hours or what maintenance the previous owner did or did not do. It starts and runs well on muffs, previous owner said it runs fine last season with no issues. We haven't had it on the water yet.

What sort of preventative maintenance is recommended since I don't know the previous maintenance history and it is almost 20 years old? I do have the factory service manual on order, it should be here by here end of the week.

I'm thinking at a minimum I should do the following:
  • Engine Oil
  • Engine Oil Filter
  • Fuel Filter
  • Spark Plugs
  • LU Water Pump rebuild
  • LU gear oil & new drain plug seals
Any other suggestions? Is the correct oil marine grade synthetic 25W-40 and the sparkplug Champion RAH8C?

Thanks!
