Powerboat electronics and rigging
The intermediate boat electronics rig
Quick answer
The intermediate boat rig is side imaging on a seven inch screen, a Spot-Lock bow mount motor, a lithium battery with a lithium profile charger, a real fuse block and a shallow water anchor. This is the level where the money stops being wasted and the equipment stops being the limitation.
This is the buy-once rig. Everything in the beginner list works, and everything here is the version of it you would have bought if you had known.
Two changes carry most of the difference. Side imaging turns sonar from a depth reading into a picture of the bottom either side of the boat, which is the upgrade that finds water you were driving past. And GPS anchoring on the bow motor holds the boat on a spot in wind, which changes how you fish rather than just how you get there.
What the three tiers actually differ on
The three tiers are genuinely different builds rather than the same list at three prices, and the intermediate rig comes to about $5,964.
Rule of thumb Boating and fishing convention rather than a published standard. Taught everywhere, useful, and not a specification. Nothing enforces it and no body publishes it.
| Tier | What it optimizes | Items | Approximate total |
|---|---|---|---|
| Beginner | Lowest total cost to something that works | 18 | $1,629 |
| Intermediate | The buy-once pick | 22 | $5,964 |
| Expert | The performance ceiling | 28 | $13,629 |
Totals are a snapshot of catalog prices at generation time rather than a quote. Items with no clean single price are excluded rather than counted as zero, and the page says how many.
What you can skip
Skip live sonar at this level. It is the most talked about upgrade in fishing and it is also four figures before the mount and the dedicated battery, and it works best when you already read conventional sonar well. Skip the 24 volt motor unless the thrust calculation genuinely calls for it, because the second battery is permanent weight and cost. Skip the second screen until the first one is limiting you.
What to upgrade first
The screen, again. Going from seven to nine inches makes a three way split of chart, side imaging and sonar genuinely readable rather than technically possible. After that, and only after you can read what you already have, live sonar is the upgrade that changes the sport, and the expert rig is built around it.
The intermediate boat rig, item by item
22 items, grouped by what each one does rather than by what it costs, so you can see what is missing as well as what it adds up to. Buy this list and you can go fishing. Every line links to the product.
See the bottom properly
$815Side imaging looks sideways rather than down. In shallow water a traditional cone covers only a few feet of bottom, so this is where the real coverage comes from.
| Item | Price | Buy |
|---|---|---|
| Humminbird Helix 7 CHIRP SI GPS G4 Side imaging on a seven inch screen at a price that undercuts most side imaging units, and the reason the Helix 7 is the default boat sonar. | $579.99 | Check price |
| Humminbird XNT 9 HW MSI 150 T transom transducer The MEGA Side Imaging transom transducer. The screen only draws what the transducer hears. | $189.06 | Check price |
| RAM Mounts fish finder mount with medium arm The ball and socket system everything else copies, with spare parts still available in a decade. | $45.99 | Check price |
Hold position without touching anything
$3,785A bow mount pulls the boat rather than pushing it, which tracks better in wind, and GPS anchoring holds a spot while both your hands are on a rod.
| Item | Price | Buy |
|---|---|---|
| Minn Kota Terrova 55 with GPS and Spot-Lock, 54 inch shaft Spot-Lock, a stow and deploy lever that works with one hand, and 12 volt simplicity. Published maximum draw is 50 A. | $1,649.99 | Check price |
| Minn Kota foot pedal for Terrova and Riptide Terrova The genuine corded pedal. This is the steering on the boat and the worst possible place to fit a copy. | $205.99 | Check price |
| Minn Kota MKA-21 quick release bracket Genuine, because this bracket is what holds the motor to the deck at trailer speed. | $84.99 | Check price |
| Minn Kota Talon shallow water anchor, 10 ft Ten feet of reach, and it talks to the rest of the Minn Kota system including auto deploy from Spot-Lock. | $1,843.99 | Check price |
Power it without weight
$599One lithium pack in place of a lead acid battery, and a charger with a lithium profile. The charger is not optional and not a preference.
| Item | Price | Buy |
|---|---|---|
| LiTime 12V 100Ah trolling motor LiFePO4 battery A BMS sized for sustained high discharge. At a 50 A draw it gives roughly three times the run time of the same nameplate in AGM. | $335.99 | Check price |
| Minn Kota MK-220PCL onboard charger, 2 banks 10 amps The PCL series carries a lithium profile. A lead acid charger either never fills a lithium pack or holds it at a voltage it should not sit at. | $242.57 | Check price |
| T-H Marine battery holder tray with stainless buckle, Group 31 A stainless buckle rather than a plastic clip, which is the part that fails first on cheap trays. | $19.99 | Check price |
A real electrical system
$304A fuse block replaces the inline fuses taped behind the console, and a main battery fuse protects the heaviest cable on the boat.
| Item | Price | Buy |

Frequently asked questions
What does the intermediate boat rig cost?
About $5,964 across 22 items at the prices in our catalog when this page was generated. Prices in this category move constantly, so treat it as a planning number rather than a quote.
Do I have to buy the whole list at once?
No, and almost nobody does. The list is grouped by function rather than by price precisely so you can see what is missing as well as what it costs. The order that makes sense is sonar first, then power, then propulsion, then everything else, because a boat that can see the bottom catches fish and a boat with a beautiful motor and no sonar is driving over structure blind.
Why are the two ladders different rather than one list at six prices?
Because a powerboat and a kayak are constrained by different things. On a boat the binding limits are console space and budget, and batteries live aboard permanently. On a kayak the binding limit is weight against a manufacturer capacity figure, every time, and it decides the answer before the budget does. Telling a kayak angler to fit a three bank charger is wrong, and telling a boat owner that weight is the constraint is worse.
Is a kayak rig cheaper than a boat rig?
Not reliably, and that is worth saying plainly. A rigged pedal kayak with a bow motor costs as much as a used aluminium boat with the beginner boat rig on it, and the boat is more capable in more conditions. The reason to choose a kayak is access to water no boat reaches, and quiet, rather than saving money.
How were these products chosen?
Researched from manufacturer specification sheets, published engineering and regulatory figures, and the recurring themes in verified owner reviews. We do not test equipment in person. Each item is matched to a real thrust rating, a real published draw, a real capacity or a real conductor size rather than to a price bracket, and the unbranded flood in several of these categories was deliberately excluded.

Researched, not professional advice. This page is compiled from published engineering and regulatory figures, manufacturer specifications and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are boating convention rather than published standards, and they are labelled that way wherever they appear. Marine electrical work is not house wiring. Use tinned, finely stranded marine cable, size it for voltage drop and for the ABYC E-11 ampacity table rather than one or the other, and put overcurrent protection within seven inches of the battery positive terminal, because everything between the post and the fuse is unprotected. A lithium battery needs a charger with a lithium profile. Never load a boat past its capacity plate, and remember that canoes and kayaks carry no federal capacity plate at all, so their stated capacity is the manufacturer own figure. Wear the life jacket, and treat early season water as the hazard it is: cold water immersion takes your breath and then your hands long before it takes your core.
