Small rooster tail

I have a 1989 19' Seasport w/full alum Bracket (adds 2' and then motor for another 24". Weighs about 4000 lbs with Honda 150 and Honda 15 kicker. My main 150 Cavitation plate is about 1 1/2 inch below "bottom of hull line". I get a small roostertail about 25' behind the 150. It is about 24" tall. Goes about 30 mph at 2400 rpm. Seems to be its comfortable cruise speed which is fine with me. Prop is a Michigan XHS 15 1/2 x 17.
This all seems to be OK but I thought I would ask. (It was all a guessing game when I converted from the 4.3 w/ Volvo- took me 2 yrs)

Thanks for comments

As a guide, the cavitation plate should be approx 1 inch higher than the keel line/hull bottom for every foot of extension behind the transom.
