Step 1 — Size the propeller first
A large, slow-turning prop grips more water with less slip. For heavy displacement — 18-20 inches at under 1,000 RPM.
Step 2 — Match the motor to it
Our PMAC motor produces maximum torque from zero RPM — no warm-up, no gearbox noise. Wound specifically for low-speed, high-torque work.
Step 3 — Design the whole system
Battery, solar, and power hub are spec’d around your motor’s real demand. Tested together — one warranty, one supplier.
