Does your Ext. box make that much of a difference?

The extension box on my old 25 made no difference i took it off, 530 hp should put you around 76-77 on gps.

Maybe there is only one, "Pack n heat". Maybe its faster. I just think thats what I remember the previous owner saying.

So what is the top speed of the 600SC Tantrum??

I ran a slightly worked solid hub 28 B1 with my old motor that was around 500hp or a little more and ran 76-77 mph gps at 5300rpm. And its for sale

What boat and power do you have?

I thought I saw two of them with 600HP on powerboatlistings.com not too long ago, one had a tall wind deflector I think. Not sure if they both were mercury 600SC's tho
