Re: Performance Gains (kk4iz)
The Phase II Kit consists of our Recreational Heads (higher compression), Carbon Fiber Reeds, Exhaust tuner, and solid engine mounts. The cost for this kit is $1534. Approximate gains with this kit are 45hp and 4-6 mph depending on your set up. This kits requires you to run a MINIMUM octane of 91, because of the higher compression heads.
Don't know of anyone in your area off the top of my head, but you can bring it here to have it installed. And its HYDRO Tec - not HYPER Tec. http://www.bassboatcentral.com/smileys/thumbsup2.gif

Re: Performance Gains (Mat_HT)
Mat, I once talked to you on the phone about my V-Max 03 250 OS motor. You told me the lower unit higher water intake was not avaliable for that motor. With that in mind how much performance would I pick up with A 21 DC Hawk boat with a phase 11 kit and lighter fly wheel? Stock I am going around 70 with 20 gallons at 5700 rpm? I would like to get around 75mph. Mark Ritz in Madison Al is a good Yamaha mechanic and I am sure is capable of doing the mods. The other options is just to order a power head from you that is done or ship you mine and let you work it over.
