The extra weight, if soggy, actually isn't a big deal. It will primarily hurt holeshot (which looks very strong) and not so much the top end. We took 600 lbs out of our bfn and it didn't speed up much.

Sorry if I didn't see details of your build - did the Excalibur install change the shaft angle at all?

My Gps phone aps have always lagged 5 or 6 seconds before they will accuratly represent top speed. If I'm Checking my 36 mph numbers I have to get about 1/2 course before it will set stedy at whatever speed I have chosen. Checking top speed I have to leave it stuck there for a while. I've tried multiple speed apps. My Airguides are surprisingly accurate at high speeds.

Cant imagine why it would. Changing the shaft angle would require shaft log and strut changes and open up a whole new can of worms. Alignment starts at the strut and moves forward... Im sure he moved the powertrain to where it aligned to the existing running gear. |

Currently i,m working on my other project a 1972 Skier were i will put the ford 351 in from my barefoot in. I need some advice about the prop, i have enough space to fit the 13x13 prop? is this a good prop to start with? the other option is that i try the acme 422 from my barefoot. |

No to both. The 13x13 is too large in diameter for that hull. The 422 is way too big of a prop for a small block with a 1:1 tranny. If you could put your hands on a Federal or OJ in the 12x14 to 12x15 range, or an Acme 1214 (12.5x13), those would give you some good baseline performance numbers to work from.
Whats up with the stringers in that boat? Looks like theyve been monkeyed with? |

ok i understand they are both not good, but i dont want to buy a new prop only for a test run. i think i will try the 13x 13 first and see what will happen.

No harm for a short test run to try the 13x13, but do plan on springing for a better prop. Not only are there few datapoints for that power train in that hull, but little data exists that would tell you which 12" prop to try based on your results with the 13" wheel. Lots of data for how the 12" props run relative to each other, which is why I'd encourage you to use that as a starting point instead. You don't know of anyone who can lend you one?
If not, I suspect we'll be back to where we started- guessing at which 12" prop to try. Did you do the stringer work or did it come to you that way? |

Ben, that sounds like a beast, spools up instantly when you give it throttle. Any numbers on rpms and speed from those runs?
I love that video. These little boats are a handful in rough water at speed, huh? |

Thank you! i have no data, it was just the first time that the boat was in the water since i've got it. I just want to try i before the lake is frozen. the prop is a 13x13 at higher speeds the boat leans over to the left, is this normal?? |

Let me rephrase...How have you enjoyed the 330? It looks like you've put a lot of work in and it is a nice upgrade from the 351. Not a ton of older models with EFI.
