Kanzaki gearbox. Where should the correct oil level be. I’ve seen posts that the dipstick cap should be sitting loose? TIA

My Yanmar transmission dip stick also only has one line - I assume it's the upper level I fill to that line.Interestingly, here’s what the YM series service manual says about the level -

The dipstick in my 3YM30 has no “upper limit” line like the one pictured, which is why I just go a little above the lower limit.
ThanksMy manual says the bottom of the stick is "minimum" and the line is "maximum." I typically fill to just below the line.

This is the KBW-10 manual, FWIW, but I'm assuming it applies to all Kanzaki's.

The age old question, “to screw, or not to screw.” The owner’s manual is ambiguous with regards to inserting the dipstick fully and tightening after completion of the task. The general consensus here & elsewhere, is to check the level with the dipstick fully inserted with the cap resting on the housing, not screwed in. My thought is that I would prefer to be 1/4” overfilled than 1/4” under filled by screwing the cap in completely. Yanmar / kanzaki should be more concise in their directions. They have improved somewhat by stamping the recommended lubricant on the the gear housing, ending that controversy., I have always checked my Kansaki Transmission fluid level with the dipstick screwed in.
Trust Rick Neary's (East Coast Marine Transmission) advice. When Mack-Boring still had mobile service for Yanmar and Kanzaki, Rick was the lead mechanic.As noted by Sailcap340's photo the line is the upper/lower limit. So the line is the correct level.
I had a recent transmission rebuild $$$ and East Coast Marine Transmission did say that the line is the correct level and you don't really want it much above or below the line. Too little is bad, but too much can also cause problems. They also said you take the measurement without screwing it in as has been said and I have commonly done.
It is obviously not an exact science since unless the Dipstick is in the exact center of the transmission the level would vary by the boat and the angle of the engine to meet the prop shaft flange.
