Back to original question. Let's get real now. If you need to ask the question, which is better... then you just need to go with the I/O and cruise on your merry little way.
I have owned this boat for over ten years. Bought from some guy who lived in Brea, CA at the time. Many years of polishing and parts to still make it look new.
This boat is an 80's "tournament style" ski boat. Direct drive - 1/1 ratio velvet drive. You can throw 1,000 hp at it and its still only going to do about 50 mph. It puts out a good water skiing wake, If anyone does that anymore. There are no ballest tanks or trim tabs or wake foils on this boat...
