@swampsnyper called it. I made it 2 seasons with the mud motor before me and my wife got sick of it. I was sick of standing up to run it, and she was sick of the noise.
I sold it for about what I have in it thanks to issues importing the kits due to 'rona, and found a 9.9hp 2-stroke merc for an even grand. Weighs less, runs faster, makes less noise, and is more maneuverable for running limb lines.
They built the 9.9s and 15s with the same head. All I need is a $200 carb and I'd have a 15, which should be about perfect. Only weighs 70lbs and pushes me solo with gear about 20mph. The 15 I'd imagine would give me 2-4 more mph, or enough to maintain performance with a 2nd person
