Most I let it go is 25 hrs, a full season for us. If doing more hrs. I'll change mid-season. Same goes for the drives.

Didn't know the early 500 EFI was set-up like that, good to know for reference. Good catch.

Actually, the earlier 500 efi's don't have this mechanical fuel pump which includes those in my 2000 Formula. My setup has worked fine as I've experienced no vapor locking problems. This is likely due to my boating area not being as hot as inland lake boating.

I looked at my motors over the weekend and I do not have that kind of pumps.

Is there a big difference between the two ways?

Ok, do you have to pull the fuel pump off to change the oil? I have a vac, but can't get anything in the hole to suck it out. Can't believe there's no drain hole.
