the 5’s are just about 6” shorter so just bolting then on will put them 1” above the bottom. I think it would be a good swap. |

Just do what I did put a notch in the hull . No biggy $1,000 bucks in materials and 5000 hours personal labor LOL .
And you get to work the fiberglass upside that's the real treat . RG. |

Hmmmmm was just talking to a buddy yesterday about how a gun would react to bolting a 4-5 on no box down the road, then space to height needed... Someone has had to do this on either boat to see....

I would leave the 3a s on the boat, I think you will be happier how it performs. 3a s and 5 s are basically the same strength and moving the prop closer to the surface will probably result in more breakage.

I raised my engines, and drives on my Top Gun with 3A's, they were in the same location that 5s would be. I was able to Plane with 4 Blades and Big Diameter. Little tab. Of course then you run into hatch issues if you are running big blowers, intercoolers, etc |
If you don`t want them coming out of the water every 5 seconds and have to constantly throttle then 2" inches below (or more) bottom is my recommendation. .. I actually went faster with that set up vs. even with bottom.
My RH drive is also the red headed step child as you know they break 10x as often due to the weaker design |

It was set up at TNT in Miami. Anything less and I believe you would be out of the water and probably be difficult to plane in certain conditions. Hard to tell from my picture, but that was the best one that I have right now. |
At what point does deep drive become too much drag and slow down? |
