I have the stock Merc pulleys and plan to keep it that way. The boat is fast enough. (did I just say that?

)

Rock Steady · Sep 2, 2004

Yes you did - and get this - your right!

I am happy with mine stock as well. For now.

Bill-I don't think you have stock ones at this time. Mine also runs 3.5 lbs. I think someone has already given yours a little boost.

Rock Steady · Sep 2, 2004

uh oh - are you not telling us everything Bill ? Do you have a 50 shot of NOS also to get the big thing over 90mph?

OldMagicfloat · Sep 2, 2004

The 575's run 5lbs of boost stock. If your only getting 3.5lbs call Merc racing and complain, they will change out the top end

The intercooler upgrade alone is a significant enhancement for engine longitivity especially in high humidity environments. You can change over the pulley combination easily from 5 all the way to 9lbs. The fav seems to be 7lbs. The real potential issue is with the head gasket life and the vanes in the Merc uppers. Adding boost does liven those puppies up though

Thanks for the information Dano.

Gilla's only got 3.5 lbs because they detune the 575 for 27' Fountains because the hulls can't take the HP :laugher: :laugher: :laugher: :laugher:

Ok now guys let's play nice..... :laugher: :laugher: I have a pair of these (575SCI's) sitting in my shop that I took out of my boat and they are sweet engines. Mine had about 80 hours on em when I pulled em out and never a problem with em. They are very mild when it comes to blower motors. I say go for it you will love em. Plus they look way cool under the hatch

29 Speedwake-ONLY 8 feet shorter than a 38 TG.

Had no complaints with the one in my 28 Pantera. Dustin makes a slighly smaller pully and a remap for a few hundred dollars that got 4mph more out of my old boat.

The whipple intercooler does add about 1 inch to the height of the engine and so it would not fit.
