How many boat engines is too many?

I'm amazed how well the low camera angles make it look like a full size boat!

Florida Boat man here, again. The Step hull Is Great for rough water, but ultimately slows you down. They're basically hooks. To achieve better performance you need Trim and Tilt, and Jack Plates. The trim and tilt will allow you to adjust the angle of thrust, making it easier to get on plane and reach a top speed. The jack plate will give you control over the depth of the engines, which also helps with acceleration and speed. Prop pitch Is super Important, but I'm not sure how that would translate into miniature applications, so you're sort of at a loss there. And finally, you made a very good observation not too many people would catch. The engines on the outside will get thrashed without something to help break the water. This is true for large applications as well. They're dragging more than providing thrust at that point. The ORIGINAL idea behind Multiple engines was to avoid getting stranded. If an engine failed, the remaining engines would provide enough power to pick the boat up and put it on plane. There's nothing worse than having to chug along at 5mph, 100 miles offshore, because you cant get on plane and cant risk burning all the fuel by plowing through the waves. Any number of engines past that is normally just a rich dude flaunting his cash and ego. And just for fun, I bet the hull you chose to model your "12 AM Quickee," after is either a Intrepid or a Contender (32'+ IRL)

I love how everyone at the actual boat show was like “yeah never enough outboards”

You can get way more speed just by changing props. For the four motor set up the props are probably perfect for the power you have, but with the 12 motor setup you have tons of power you aren’t using. You can see this by the fact that the boat had an almost nonexistent 0 to top speed time. You need steeper pitched props to utilize all that power. For reference look at offshore race boat props. That’s probably the level of pitch you need. Where they are almost parallel to the direction of boat travel through the water. You could even do sequential pitch on each set of 4 motors. The ones closest to the boat being the shallowest pitch and the third set back being the steepest. You could definitely do a revisit video testing prop pitch.

This channel is like Tool Time with an insane amount of imagination and energy.

I was waaaay to happy to just keep watching B-Roll of the 4 motor setup. I am so easily entertained......

what if u use real boat engines

Ok, I really want to see 1:30 done with a full size outboard now lol The baby outboards are so cute!

Hey Peter, if you want the boat to be able to turn in the stacked rows of 4, you'll need to invert the direction of the second set of motors. Having multiple pulling in the same direction will result in a "crab walk" or "strafe". / = crab walk / = turn / \

With the addition of the smaller side boats, you created tons more drag. Also, the motors in rows wasn't effective because you wont go any faster without an increase in rpm, which would increase the drag from the slower motors. An impeller setup would be fun to watch!

I love this idea. From what I can tell, the motors on riggers was just too much, and putting them in rows behind might work if you make the propshafts longer on the motors the further back they are. Also the props are possibly too small since there is a bunch of bubbles from cavitation, but first try putting the props deeper in the water the further back they are and if you still see lots of aeration behind the boat when its not on plane, increase prop diameter and or pitch.

the prop pitch dictates the max speed. No mater how many motors you add, it will always reach the same max speed. You need to increase the pitch together with adding motors to gain more speed. Anyway, thanks for another hilarious project!

You have a planing hull, with lifting strakes and all the weight is at the rear which does not permit the lifting strakes to 'lift' the boat. Add some weight to the front and it may fix the issue, and will also reduce your rear drag.

I pretty much had an idea about the outcome from the start, you guys confirmed it. It's not just the number that matters. There are fluid dynamics at play. That said you just need bigger faster motors, not more of them. Besides more =more headaches and maintenance

I like the attention to the little details, like the rotating radar on top. The original row of motors might done better if there was adjustable trim. Also more might be more beneficial to run at top speed even if towing a skier.

I love the attention to detail, especially on the "little johnson 25" stickers. I grew up with a small johnson 15 outboard that looks just like the ones you made.

I agreed with the boat show guys "never enough motors" until you sent it...its be col to see some different prop configurations as well...and oh yeah you need to make it fly :)

Peter: drops 3D printed outboard in fishtank Fishes: "ahhh noooo... not again !"

I like how Peter talked trash on the Miami water when his fish tank was absolutely foul smh

I love how the consensus of the boat show was "never enough motors"😂
