For reference- here is the "marine survey edition" transom scumline with a 20" shaft F100, a 30" shaft kicker and four, yes FOUR transducers. Two of which I was just testing before the big boat was ready. You can see the scumline versus the notch, and what the kicker does to "tip" the scumline. On paper, the F100 is 367 lb. Plus maybe 8 lb of oil. The 6hp Tohatsu SailPro is 58 lb.
Batteries are forward. The fuel tank is in the console- centerline maybe 3 feet forward of stock.
The thing under the skeg is this hydroshield. Plus that's a stern lifting prop.
And no. The dog isn't mine.
