Well she is finally running, and running pretty strong. I love the fit and finish of the hull with the 3/16th bottom and the way it handles with the GTR, she is a little on the heavy side to really be a runner. I will post up some pictures later on today of the completed project. Motor Work Includes: Heads with 1 peice valves, ported, polished, decked 0.065 beveled valve guides, and a little more. Intake work is port matched and polished with the old style BPS intake adapter.(with 1/2" carb spacer) Bps cam with new lifters. .020 over sized stock pistons (still dished) #4 timing advance (still need to get it dialed in as per ground strap on spark plugs) Mikuni carb (waiting on a Yost power atomizer to try out this weekend). Its is running a 162.5 and is perfect color. I will try some needle adjustments to get her dialed in form 1/4 to 3/4 throttle range. Running a mud buddy big blade right now, but have a gator tail prop comming to run on it. Ran the boat with noramal boat gear, 2 batteries, 2 people, and 13 gallons of gas and the sweet spot was 5150 RPMs. Got in it by myself and and she was at 5300 RPMs. Motor 1.jpg Boat 1.jpg |

I'm waiting to run the Gator Tail prop to post some speeds, lets just say she was over the 35 MPH mark. |

Why does it matter to say what it ran with the MB prop? |

I love the v front. You can nose up on a wave and not have to worry about getting wet like a standard square front. I had 2 inboards get in front of me creating a big wave and I tried to get the spray to hit us from crossing them and could not get us wet. |

Awesome dude! You'll probably run 37-38mph with a fresh GT big blade. |

JamIe, unless you're after top end only, call Hoyt and get yourself the new gear and thank me later. |
