1988 140 Evinrude lower unit

Looking for help pulling my lower unit. I have removed all bolts from lower unit, disconnected shift linkage and removed the trim tab. I cannot get this thing to budge.... is there a hidden secret to getting it off?

Another bolt behind the trim tab ??? or close by ??? Mine has 5 holding it on from below plus the trim tab.

Looks like 7 bolts ... 4-#72 and 1 each #66, #71, and #70. At least one may be hidden under the trim tab!

Mine is a 1985 so may be different.

Well I feel like a goober now... Thanks for the help! The hidden one under the trim tab got me I fought the good fight for 2 hours before I realized it...Live and learn i guess. The reason I pulled it is because I had water in my gear oil, and water and lube coming out of my prop. All the gears look good, and the clutch dog looks good also. Should I just put on new o-rings and gaskets and try again?
