Longtail length and transom height (video)

Just wanted to share my video over the weekend, to save other guys that end up with a hodge podge of parts a fair amount of headache also maybe help show why transom height and shaft length matters on longtails.
So long story short, bought a "cheap running boat", new props, rebuilt motor, can't get over 2500 rpm without the prop just running out the water, come to find out transom height and longtail length matter.
Long story for anyone bored enough to listen, bought this setup from a buddy for what I still consider "cheap", prop was smoked, first backwater 9x7, much better speed but just didn't feel like it had the push, so bps 9x7 looked a lot nicer, pushed way harder on take off but I lacked rpms, rebuilt this old 'water buffalo'(i think thats what you far older folk call them), it was low on compression, thinking how hard can it be (have 15yrs automotive experience I don't need no help), I was wrong, Russ from on here saved my tail many times with rebuilding this, and many times wanted to just give up and start over with something new, I kept tinkering got it back together, won't hardly start, reset valve clearance since apparently the 006 and 007 being stuck together isn't right... I'm sure Russ rolled his eyes thinking this guy in Kansas is literally brain dead. Ok, she starts, sometimes, back fires does all sorts of weird stuff at the end of the year, I park it and just give up. Then read back through the service manual thinking I had to have just missed something dumb, it's a lawn mower engine ffs, oh ignition coil gap... yep that'll do it, glad it's 1970 again small engine engineers... So now it runs not half bad, much better than before I'm fairly happy with it (the governor, i think, rattles sometimes not real sure what to think here so if anyone has an idea I'm all ears lol i feel like all of that went back together smooth on reassembly but I also can't set valves or ignition gap so wtf do I know.) So anyways runs pretty good, sounds super pissed at higher rpms out of water, but my 170# aint holding this thing in the water past 2500-2800, maybe low 3000s if im just 2 handed giving it hell, bend the cav plate every which way, no help, ok wtf, yep finally asked questions and my hodge podge of parts is just that. So tall transom, shorter shaft, so much headache.
Thank you everyone for the help and answering questions directly and indirectly, except you giga (I feel like others will accept me by poking fun at you) good day folks!
IF ANYONE CAN TELL ME WHY BUYING A TALL TRANSOM 77" BACKWATER 37EFI IS A BAD IDEA PLEASE TELL ME BEFORE I SPEND MORE MONEY
