Good question--I believe that the Mag and Mag HO with the Raylar kit will put out the SAME hp since the kit changes those two things anyway. Someone please correct me if I'm wrong of call Ray at Raylar (tell him Patrick from Boat Bling sent you). If you are NOT going to do a kit, get the HO, its money well invested IMO. The standard warranty is 1 year, however you can buy a warranty that lasts for 5 years. I think I would--obviously unless you are going to put a aftermarket kit on it then its void, so no need to spend the money.
The Bravo 1X is the new standard for the Bravos-- first verson available. The XR is the highest version available (standard on HP models and optional on HOs)
Can't wait to see the graphics you choose--Brett and those guys at Magic/Sleek are awesome.
