There is one for sale in fl west coast silver with black windshield and rails I will look for the listing

That is probably the baddest azz 35 I have ever seen. They are asking top dollar for it though.

Would that be a 35 525 boat in the St pete, bay Pines area?

I concur. I am a lake-river boater (Lake Havasu AZ) and I don't need or want a bigger boat! This 35 is big enough for Pete's sake. My last single engine boat was a 25 and it was enough here, but I have always wanted a big fast Fountain.
As far as performance goes I am quite impressed with the 600's. My 525 35 Lightning boat would do 100 on its best day (I saw 100 once and 99 once). But these 600's are a different animal. Since the boost is controlled by a bleed valve (like the waste gate on a turbo), I expect them to run about the same all the time. The 525's would lose 5 mph in the heat of the desert in the summer leaving you with a 95 mph ride, but I think the 600's will still run strong in the heat. Anyway we saw 106-107 mph the first time out in 75F and I expect similar numbers in the summer heat. Also I am pulling the mufflers in favor of silent choice and I expect some gain here as well from what Kelly's experience was. If I see 107-108 with no mufflers vs 95-96 in the summer heat with 525's I would say that is a significant difference. Then if I still need more speed the Whipple mods will easily get me to 120+. Is that enough bang for my buck?

sure seems to be alot of bang for the buck... would you share some pics with us?

I don't think I can post photos. Maybe Kelly can put up a couple of the ones I sent him.

35' is the biggest seller for a reason unless you run the ocean go with your 1st choice!
