Well that's an interesting bit of history and effort. Good on you. If you get it running right, maybe someone can use it, if you decide not to ...
Yeah, from everything I've read, and been told (while trying to trade in my Honda ...), the Tohatsu's are the cream of the crop. They never skimped on anything and they under-rate their motors so they are always strong in comparison.
OTOH, my Honda BF50 EFI was pretty much a joke. Any good running Johns-a-Rude 40~50 would have whup'd it hands down. Not smooth and not a lot of power. It was running well and it RPM'd right where it should, but was annoyingly noisy at various RPM, growled at cruising speed, and was not at all what I expected out of a three cylinder.
Now onto its third owner, and he'll do OK as it's going on a 16' aluminum fishing boat, paired with a 10HP Honda kicker ... Plenty for his rig. Not enough for my 18' hand laid fiberglass hull with built-in wooden furniture ... Johns-a-Rude 70HP looper for me next
And if that don't get it, I have a 140 V4 bubble back hiding in the wings
