I am still in school so my experience is limited. We have Solidworks there and I like it. Making parts and assemblies is easy. I haven't done any more than that. I just got an internship at Raytheon and they use Pro/E. Holy $h!t that is a confusing program to use. I took about 1.5 weeks worth of...

So by having more low end torque that could be the reason why that engine was able to get the boat on plane?

The reason for these questions is from a video I saw. Two engines were mounted on a boat. Both were 225hp engines. One was a 4-stroke and the other was a DI 2-stroke. The 2-stroke has a lot more low end torque. The boat was a heavy boat. While running the 2-stroke the boat accelerates and gets...

There are several ways to increase lower end torque. Increasing displacement and tuning it for lower end power. A simple exhaust pipe mod. Using fuel injection instead of a carburetor. A 2-stroke engine vs a 4-stroke engine.

So I understand an engine with 200lb-ft of torque may have 300hp at 7878 RPM and the 300lb-ft engine will have 300hp at 5252 RPM. This means with the same gearing the boat B will hit its power sooner and accelerate faster but top out sooner. Correct? Maybe I am wrong about torque in this...

I don't understand that explanation. Why is it physically impossible? Where did you come up with, "Boat A's propeller spins at 3/2 the rpm of Boat B's at that operating point"? I stated that they have the same gearing. Include same prop. Therefore both propellers must be spinning at the...

I have a question having to do with the affect of torque on a vehicle. I have 2 situations to make it easier to respond. Case 1 There are two boats. Both are identical, identical in weight, drag, etc. Boat A and boat B have single 300hp outboard engines. Although boat A's engine makes...
