This is a Baja by Fountain and the X-dim is right off the performance report. The earlier Baja by Fountain boats had higher X-dim but for some reason on ours they went back to or close to the Baja by Brunswick X-dim.
I will post the transom question in the Baja section, hopefully someone there knows the answer. Thanks again for all the help! |
Take a look at this post. http://www.offshoreonly.com/forums/b...25-outlaw.html It looks like he had the best rusults at 3.5" depth.
Here is a post I started a while back http://www.offshoreonly.com/forums/d...ive-depth.html |

Griff, I agree, without a box 4.5 to 5" should be your target. But if he adds the box he should go up higher, more like 3".
I would go with the -3 lower like Jason said and have a 1/2 inch spacer ready. |
Rick, it was great talking with you the other day. Now we can keep track on facebook also.
If it were me, I would drop the engine in and run it this season. There is a lot of rigging to change over and it's almost April. Get some numbers after doing the engine upgrades and think about the box and drive next winter. I have some ideas we can talk about when tied up at the river. If you get 575 HP out of the engine you should be in the low 70's without any drive adjustments. Besides it you do everything this year your boat might be faster than mine. That will really screw things up for me. :lolhit: |

My X-dimension is 15.5".... does anyone the exact distance from the center of the drive shaft to the center line of the prop shaft of the Bravo 1 X-Drive?
21-13/16. |

If you get a 3" raise Imco box, you also have to raise the engine 3".
I would just try the -2 shorty first without the box. You most likely do not want your propshaft depth any higher than about 4.5-5". All that will happen is you will get more propslip and less bowlift. |

Search Wildcard's posts. Shorty by itself doesn't do much of anything. Extension box works great with good horsepower. WIldcard did the 3" extension box and standard lower. It worked great. He tried a 2" shorty for a total of 5" and it was too much. So, extension box is key. 2"-3" seems to be the magic number.
I would do the neutral box and your 2" shorty to avoid the headache of raising the motor. What power do you have. If it's stock 496 or 496ho I don't know if you will see anything. Wild card put a 525efi in when he did the box. and then later switched to a 600sci. 500+hp and the gains become very noticeable. |

Guys... thank you for the great replies! :coolcowboy:
I was not aware that the engine also needed to be raised as well... that is not going to be an option. We are going to have well over 500HP when the engine is all done. So the Neutral Box and 2" Shorty will be the way we go. Griff, a prop shaft depth of 4.5"-5" is a good target? I want to understand why is this? Because, I have some people telling me I want the shaft level with the keel. This would seem very extreme to me. I want to get the most out the boat but I do not want to sacrifice the basic handling abilities. Thanks again everyone for taking the time to help! :drink: jeffswav, do you boat on the Kaskaskia River? If so, we'll have to meet up one day for a run. |
