Identify the exact motor
Brand, model, voltage, thrust, shaft, water rating, maximum current, and manual revision.
Clear the electrical limits
Battery voltage must match. Continuous BMS output must exceed published motor draw with headroom.
Size the trip
We model a use pattern, water factor, usable capacity, and reserve—then display a range.
Keep rigging inside the source
Breaker and cable guidance appears only when a manufacturer table covers the motor and length.
Separate money from rank
Commission availability never makes an incompatible product eligible or changes the match order.
Runtime model
Why the answer is a range
The current draw shown in a manual is usually a maximum, not a trip average. RigCurrent applies a duty factor for positioning, mixed fishing, or sustained travel; adjusts for conditions; reserves capacity; and widens the answer for uncertainty.
It does not model hull efficiency, propeller damage, battery aging, weeds, temperature, or changing weather with enough precision to promise miles or a safe return.
Update policy
What “reviewed” means
A reviewed profile links to a manufacturer product page, manual, or rigging guide and records the review date. Prices are planning estimates only. A model is removed from purchase-ready results if its source disappears or key specifications conflict.
Safety boundary
When the tool refuses an answer
Heavy loads, 24V and 36V banks, extensions outside published tables, mixed battery systems, and installations with uncertain manuals are flagged for qualified marine review. The goal is fewer expensive mistakes, not false authority.
