My chainring cracked, so I bought 3 different sizes for $5.95-$6.95 each. Also spent $10 worth of nuts and bolts, some stainless.
Spent $20 on running lights, front and rear.
My 4hp engine cost $255. My brother's diesel engine cost $40,000.
My used Diamondback cost $125. It came with front and rear disc brakes.
Scooterguy frame-mount cost $250.
High-performance wheelset cost $160.
Armadillo tires cost $80.
Happy Time expansion pipe cost $75.
So my B-I-L's boat cost over $100K(not including expensive fishing gear) and looks like other fishing boats.
My custom motorized bike cost $1K. It is truly unique.
Absolutely no comparison to a fishing boat.
