so the questions is : should I spend money on used Herrings and gain what for mph ? or look for a used pair of 600's ?
105mph would make me want to keep the boat for a couple more years ..

I say Whipple your 525s and get 780 dependable H.P. Look into it. about 20 k.

Your boat should be running 96+ no matter what with 525's. With Herings you should be at 98. Send the ecu's to Whipple to up the revlimiters and gain hp. You would be right around 100-101 but you would have to run 93 octane. The 600 boats run right aroun 100-102. Juiced up they'll run 105+ like Franks. Its alot cheaper than a re-power or whipples and you'll be right around 100. Plus the drives will still be ok.

any idea on the Herring size for a 525 xr with shorty ? I will be calling whipple ...Thanks

Back to the boat on Ebay... Is it a good one or?

Sorry did not mean to hi Jack ....I love my Quattro ..Great riding , great handling , excellent acceleration , no problems running hard in rough water ... roomy deep cockpit area , wind screen knocks down the wind a lot .. The Rooster tail rocks !

Id say its a good boat rick besides the paint repairs that have to be done. Also under the 198K they're asking. The 39's are a great boat!!

I'll ask Mike tomorrow for you.

most painted rub rails peel .. the pop cleats clear peels ... minor .. .just had my rub rail area re done ... Looks new again ! ..I may be Bias but I wouldnt sell mine for that , regardless of the market ! sure a beak is less .. but really ? I always wanted a TG until i got an OL

If you look at the pics the areas arnt around the rub rail. I would say 185-190 would be a nice deal. A TG to a 39OL.....please......not even a competition!
