Is 120hp too small for 21ft center console

[gotomgo]

I swore I would not hang a force motor on the back of my boat.but money's tight and I'm I'm desperate need to get back on the water .I bought 2 motors off craigslist.one ended up being a 20" shaft couldn't use it and the other had cracked crank case I was able to partial refunds for both motors but after delivery fees and gas and suck I'm already out about $$600 in wasted money etc...,there's a local reputable used outboard guy near me. He has a 98 force 120 25" shaft. I'm really thinking about buying it.i had a 150 blackmax .boat screamed jumped on plane and hauled assess. Repowered with a 175 blackmax...only lasted a few mins but seemed powerful.my boats a 78 steplift center console. I mainly have 3 kids and the wife on it. So we mostly go slow or cruise as my oldest daughter is the only fan of speed. We go crabbing I. The river and bottom fishing in the bay.
I'm not worried about top speed. Do you think with hydrofoils and a good prop this motor will work on my boat?
