How fast is a 31' Hustler straight bottom V with a pair of 300 hp Mercury Pro Max outboards The motors are turning 23 " pitch 3 blade Mirage props. It's also bottom painted. I am guessing 65 to 70 mph. Thanks.

There's no 31 Hustler. You mean 32?

I'd guess similar. If the motors are Pro Max's and not 300X's you'll be down about 70 hp's (total) and I'd guess maybe mid/high 60's w/those.

If current set up can turn those wheels 6000 RPM (assuming 1.62 gears which most 300's have) you'd be at 72.6 @ 10% slip.

The X's are monsters!

Maybe it is a 32' , there were no identifying numbers, but it was about the same length as my 311 Formula

It's a 32 I have one also but whit diesels 320 hp each and see 72 mph on the gps.

but I had a friend whit a 31 scarab Viper and that was at least 1 ft longer then my hustler 32 !
