358 sonic question
 

2000 sonic 358 with twin 502 efi (415hp) ? with 500 efi's know people running 75 mph. any info
also any one know of cost of installing ac in this model boat if it did'nt originally come with it ?

Is that the one with the green stripe for sale in NJ? 502efi = 415hp. Should run 69-70mph. That's the info we noted when we were searching for one. Did you check with www.offshore-performance.com in MD? The are a good source for 358's, think they have a couple right now. They are great to deal with!!! We're still shopping ourselves, just haven't gotten our boat sold yet. Your best bet would be to call them, I see there website isn't that up to date with the used stuff compared to what they have in the boat shopper..... The 358 is a fabulous boat!!!

Not sure on the AC cost install.
