I was thinking about - Re-Powering my 1990_ 4 Winns 221 with a 502 or ?? this winter.

I was wondering what has worked the best (221 owners) and did not want to re-invent the wheel.

Also, will the 221 haul handle the increased HP and would the boat >> be stable at higher speeds, or Not worth the effort or expense ?

How does... (or what would one expect) the Libb. 221 to handle at 80 + mph or so on smooth lake water (would the boat be unstable) ?

Is their another boat that (older boat) that would be a better candiate for repower and go fast with 600 HP engine ?

Advise-Sell your non-performance boat with its non-performance hull and buy a nice( low at todays cost )good used performance boat to achieve your needed results.
You can't make a high speed boat out of a boat that was only designed to see 50mph speeds.

If you put 600 hp in a properly rigged Donzi 22 Classic, you could see mid 90s and have a sweeeeet looking boat.

Since I made this Inquiry... I saw alot of go fast (87 to 95) boats that are going at low prices, not a lot of work & labor involved.

Thank's for the Advice.

Libs are not a fast hull but they are built like a brick chithouse. They will take some power to move but you would have a nice sleeper!

600hp should put you in low upper 70s.

I would sell and buy an actual performance boat that probably runs those speeds stock.
