jeeze i can't believe the haters of this vid. It's pretty awesome to see young engineers at work. Scetching up designes, fabricating the parts, getting into the tuning software to set the fuel and ignition parameters at differing loads. It would be interesting to see if its more economical with a turbo as opposed to N/A especially when under the differing load conditions of the sea, and also interesting would be how to solve the turbo drain problem when you have the motor trimmed right up. Best of luck with it, seems like so much fun!

Power is fairly irrelevant on a boat once you get to a point. Because you can only spin a prop so fast in water before the water can’t keep up and an air bubble forms around the prop and you go nowhere. The difference come from the different props. They need to try a new prop I think

While I absolutely LOVE how you guys are engineering that Honda 225 with turbos and custom parts, great job on parts manufacturing and engineering. But there is no way that engine is pushing 500 HP. That boat probably runs 40 MPH on a totally stock 4 stroke 225. If that engine pushed out even close to 500 HP the boat would be 60+ MPH. Case in point I had a 30' boat with twin 250 Evinrudes completely stock and it was a 64 MPH boat. If I were getting 500 HP from a single engine it would have been even faster due to less weight and lower unit drag.

Pretty impressive for a couple kids. Tuning can make our break a turbo. The motor is already high in compression so your gonna need to pull probably 10 degrees of timing. Run e85 or 100 octane to keep it safe. Add fuel to get your afr right and that motor should get after it pretty good if turbos are the right size. Also you got the hull deep in the water. Trim up until your just riding on the last foot of the stern and it will make a huge difference.

He slid down the engine and you could see the propeller slice marks on his leg (and prob personal parts-but they were left in the water). Years later he had to have that leg amputated. Do yourself a favor and use a harness if you're making adjustments on the engine.

They were getting speeds of 38-44 mph at almost 2000rpm less than WOT of the stock motor.
