Is the motor a true 350 mag? If so I would think you are down on power. I had a 350 mag in a 21ft Maxum and would get 65-67mph GPS. Then I put it in my 22 donzi for a couple of seasons and would run 62gps. My donzi is a little heavier then your villian, I would think you need to trim more, do a tune up, and/or try a new prop.

Go to page 102 in the link, there is a comparison of 5 small power boats in 1987. I have the 206 Formula and it ran 55-56 or so on the GPS with 270 horse. Pretty cool '80s flashback in some of the automobile ads too

With the true 350 300hp mag. The 260 is a regular 350. I would see 65 with just me and my dad in the boat with 1/4 tank. The boat didn't way anything. Also it would get up out of the water with only the last foot touching. I beat a lot of 20-25ft performance baja's. I ran a 22p 3 blade up to around 4800-5000. But the same motor without being refreshed pushed the 22ft donzi up to 62 when it was 20+ years old

Wish they mentioned what props they ended up with, even though not a whole lot available back then.

I've found the Mirage's to have too much diameter and blade area for single small block alpha's in smaller boats.
