What does everbody consider a level boat when checking and changing fluids? I have been using the hull rails as level, but now I am questioning myself thinking the engine is not level.

Also, after reading a ton of different threads, might as well see what others are using for Main Gearbox oil and V-Drive oil these days. I have looked at the manual and of course the numbers don't match anything on the Inmar site.

One other thing.....I heat up engine to check the ATF oil, but do people do the same for the drive Unit....I sort of check at the same time.

Just curious as to what other people do.

Thanks
