Speeds 31ss
Brother in-law looking at a 31ss, wanted to know the difference in the motor packages,(speed) he is trying to find a 96-97 with 502's, but the price goes up very quick from the 95-96 model years. Most of them have 454 magnums. So what are the numbers on the two different boats.
454 magnums mph ???
502 magnums mph???
454 magnums mph ???
502 magnums mph???

78 - 80 is what they are saying with the HO's, but I find that hard to believe. I was wondering if anyone that actually has them can tell us what they have run.
Ours runs 69.2 with the Mags and I plan to have the props lab finished at merc this winter, hopefully this will give us 70 - 71. I really find it hard to believe that another 50 hp will net 10 mph. But my speeds are in fresh water.

OK I have a 1994 31ss with 330's on roids they make about 475 HP it runs 73.6 on GPS with a 2-3 foot chop it runs 70 on flat water. I'll believe it when I see it....496's and 80mph I doubt it....

Everytime I get close to WOT I get an evil look from my wife. She is not quite ready for it. However, I run 62 to 63MPH at 4000 RPM with 3/4 fuel, 4 people plus gear. I think 77 MPH is realistic number.
When we confirm I will post again.
