The trouble with an outboard on a catamaran is the engine depth is critical to good performance. When it's behind a monohull, the hull pushes the water away, so the flat plate above the prop is always in line with bottom of the hull. If it's any lower, the round part of the skegg creates drag, and worst of all, the back pressure of the exhaust, boggs down the engine. It's like shoving a rag into your exhaust pipe. I have done a lot of designing in this area, and I built a 3rd type hull, like a triangle toward the motor, to keep the prop at the right depth. Your prop looks way to deep. And when you add waves through the 2 hulls, the depth keeps changing as well. JD
I am looking to do this same thing. Have some questions please. 1. Can you send me some clear, close up pics of the motor mount setup? 2. How fast will it go? 3. Can you send some pics of the seat setup? 4. Can you send pics of the Storage box setup in front? 5. I see the back end sits REALLY low. And scariness when motoring? Looks tipsy when you hit the wave. I want to go into the gulf near Destin FL. THis looks SOOO cool. Thanks...J
John Ambrosius Sorry for not answering a rarely look at messages in You tube I have to search the pics this was the first tryout and the front/back ballance was not optimal can you keep in contakt throug email ( hartman@hotmail.it
The plans only exist in my head. , just remove the trampoline, atach a plate of trespa / water proof ply wood , na a 90° device to atach the engineering to , and go faster than any othe floating device 🤷
