    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.

    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.

    Hey Mat I have a couple of questions for you. I have a 2005 Champion 206 with a 2005 Yamaha 250 HPDI VMAX. I am using a 25T1 prop and can only get about 5300 RPM and 65 MPH. My hole shot is good for 2 people tournament loaded but is kind of slow when the live wells are full and my gas tank is near full. I want to increase the speed of the boat and get a faster hole shot and I am thinking about sending my motor to you for a phase III kit installation on the motor. What do you think that will do for me regarding my hole shot, RPM's and MPH. And how much additional horsepower can I gain. Also, what kind of warranty do you offer with these modifications?

    Phoenix 20 PHX with 250 SHO - running stock 25 T2 prop ...before the flash with a loaded boat and two people 74.2 mph at 6125 rpm...after flash 77.4 at 6235 rpm...Flash is good for solid 3 mph gain without re-propping..think with a 26 T1 I'll gain another 1-2 mph..

    79.8 mph run my buddy made by himself while I filmed from shore..Lithium Pros going in next week!







    Updated - changed prop to 28 Bravo XS - hit 81.4mph with one person, and 79 with two and load of gear

    That's cool! When I last talked to Hydro Tec, they weren't flashing the 2.8 L SHO motors. What hp did the Hydro Tec flash take your 150 SHO up to? What boat are you running it on? What is your new gps top speed & rpms? What's your prop to pad height, & what prop are you running?

I hope to run it this coming week. I'm running it on a Phoenix 618 with a 23 Tempest Plus set at 3 1/4 prop to pad height. I'll post my results when I'm able to run it. Thanks in advance for the info.
    your gonna need more prop, sent you a PM

    I’ve got a 1988 Yamaha 175 on an 18ft bass boat and I’m just curious if anyone knows around what kind of horsepower gains I could get out of the hydro-Tec heads and new reeds and re jetting the carbs, I’m running a 25m prop and I’m only getting 4-4300 rpm and about 55-58mph, hole shot is decent loaded with fishing gear (and I mean loaded lol) an 1 more person regardless of their size everyone I’ve talked to thinks I should be grinning 5500 max on that motor but I can’t even get it to 5000! And it absolutely drinks the gas because I’ve got to stay in it the whole time! I appreciate any help!!
