Electric boat trailer winches are rated in a language of their own, and this guide prints it honestly: Fulton rates its powered XLT pair by maximum boat weight (not line pull), Dutton-Lainson rates the StrongArm by dead weight, and the budget Megaflint prints three numbers at once (rolling, marine, dead pull) that must never be merged. The previous version of this guide actually had the right products — including the powered Fultons, which a sister guide on this site once misread as hand winches (corrected there; the correction is documented in this site’s research) — but it printed amp draws and a warranty split that no maker publishes. Both are gone. Hand-crank boat winches live in our boat trailer winch guide; general trailer electrics are our electric trailer guide.
How we researched: Fulton/Horizon Global, Dutton-Lainson and Powerwinch maker pages, manuals and catalogues, with ASINs tied to maker part numbers and UPCs (the Fulton pair ties by UPC exactly). We do not test winches. Where a maker publishes no figure — Fulton publishes no amp draw for either XLT — this guide prints none.
Short answer: most powered-trailer buyers take the XLT 10.0 Powered (boats to 10,000 lb, wireless remote, 5-year warranty). The StrongArm SA9000DC is the brake-and-harness pick; the XLT 7.0 covers mid-size boats; the Megaflint is the budget door with its conflicts printed.
Size by the boat, the way the makers do
| Your boat (loaded, on the trailer) | Maker class that covers it | Picks here |
|---|---|---|
| To ~5,000 lb, to ~18 ft | Megaflint marine class / smaller StrongArm family | Megaflint |
| To 7,000 lb, to 20 ft | Fulton XLT 7.0 Powered | XLT 7.0 |
| To 10,000 lb, to 26 ft | Fulton XLT 10.0 Powered | XLT 10.0 |
| Any class, brake-first priority | StrongArm dead-weight rating + automatic brake | SA9000DC (3,000 lb dead weight; DL’s rolling-load chart covers far heavier boats on shallow ramps) |
Ramp safety: power-out is not a brake. The StrongArm’s automatic friction brake is the only true load-holding design in this table; on every model, keep the tow vehicle braked and chocked, keep people clear of the strap’s line, and use the manual override/crank knowledge BEFORE the ramp, not during a problem. Fulton’s own instructions require a battery of at least 650 CCA and gauge-by-length wiring — the electrical install is part of the winch.

1. Fulton XLT 10.0 Powered (500621) — Best Overall Electric
The XLT 10.0 Powered is Fulton’s flagship trailer winch: rated by the maker for boats to 10,000 lb and 26 ft, with power in, power out and free spool, a wireless remote that also runs its LED lights (back and bottom — dawn and dusk launching is a real use case), a 2 in x 15 ft strap with a swivel hook, manual override with standard tools, and the Sharkskin corrosion finish. Two honesty notes: Fulton’s “rated line pull” field simply repeats the boat-weight figure — it is not a dead-pull rating, and this guide never presents it as one; and Fulton publishes no amp draw, requiring instead a battery of at least 650 CCA with gauge-by-length wiring. Warranty is the maker’s flat Limited 5 Year (an earlier version of this guide printed a lifetime/5-year split; the maker publishes no such split).
| Maker part | 500621 (UPC 016118008753) |
| Max boat weight | 10,000 lb; boats to 26 ft |
| Line | 2 in x 15 ft strap, 360° swivel hook, 3-position strap guide |
| Operation | Power in / power out / free spool; manual override |
| Remote | Wireless (also controls LED lights) |
| Finish | Sharkskin corrosion-resistant |
| Weight | 24.7 lb (maker table) |
| Power requirement | 12V battery, at least 650 CCA (maker instructions); amp draw not published |
| Warranty | Limited 5 Year (maker) |
Pros
- Biggest boat class here
- Wireless remote + lights
- Published 5-year warranty
Watch-outs
- Boat-weight rating, not a dead-pull figure
- No published amp draw
What owners say: Maker documentation is the primary record for this pair; the old guide’s owner framing was not carried over where it could not be verified.
2. Dutton-Lainson StrongArm SA9000DC — Best True Brake
The StrongArm is the brake pick, again: a true 3,000 lb DEAD-WEIGHT rating (a different, harder currency than boat-weight classes), the automatic mechanical friction brake plus dynamic brake, a clutch that can be slipped for controlled payout, an emergency crank, and a 25 ft vehicle harness in the box — it is designed to run off the tow vehicle’s battery, engine running. Its deep record is in our electric trailer guide, where it also leads, and our boat trailer guide.
| Rated capacity | 3,000 lb dead weight (single line) |
| Gear ratio | 570:1 |
| Braking | Automatic mechanical friction brake + dynamic brake |
| Clutch | Controlled freewheeling (can be slipped) |
| Backup | Emergency hand crank |
| Power | 12V DC via 25 ft vehicle harness (included) |
| Duty | Intermittent — about 4 min continuous (maker manual) |
Pros
- True automatic brake
- Dead-weight rating
- Harness included
Watch-outs
- Intermittent duty cycle
- Heavier install than a strap winch
What owners say: The Hull Truth dealer corroboration of the 3,000 lb figure is part of this site’s StrongArm record.
3. Fulton XLT 7.0 Powered (500620) — Best for Mid-Size Boats
The XLT 7.0 Powered is the 10.0’s sibling for boats to 7,000 lb and 20 ft — same strap, same wireless remote and lights, same Sharkskin finish, same 5-year warranty, same 24.7 lb maker-table weight. Fulton’s spec table lists a 20 ft “cable length” for this model (26 ft on the 10.0) although the strap is 15 ft; the field appears to describe the power cord and retailer feeds copy it inconsistently — flagged here rather than repeated as a strap figure.
| Maker part | 500620 (UPC 016118008364) |
| Max boat weight | 7,000 lb; boats to 20 ft |
| Line | 2 in x 15 ft strap, swivel hook |
| Operation | Power in / power out / free spool; manual override |
| Remote | Wireless (also controls LED lights) |
| Finish | Sharkskin corrosion-resistant |
| Weight | 24.7 lb (maker table) |
| Warranty | Limited 5 Year (maker) |
Pros
- Mid-size class covered fully
- Same features as the flagship
- 5-year warranty
Watch-outs
- Boat-weight rating only
- Spec-table cord/strap ambiguity (flagged)
What owners say: Maker documentation is the record for the pair.
4. Megaflint Trailer Winch (Model 1) — Best Budget Electric
The Megaflint is the budget electric, printed with the most honest label set on this page: 6,000 lb ROLLING, 5,000 lb MARINE, 2,000 lb DEAD PULL — three numbers for three jobs, from the maker’s own listing and manual (its title’s “boats up to 6000 lbs” is the rolling figure; the spec block’s max boat weight reads 5,000). Power in/out, freewheel, dynamic plus friction braking, a corded rocker remote and a manual crank backup. Two conflicts print unresolved: the listing’s field calls its 30 ft line a cable while the current manual specifies Dyneema synthetic rope — check which version a listing describes before ordering — and its warranty appears as 2 years (manual) and 3 years (a seller feed), so this guide prints Not published. Its listing’s own caution block is dominated by one warning: tighten the clutch fully before pulling.
| Ratings (as published) | 6,000 lb rolling / 5,000 lb marine / 2,000 lb dead pull |
| Line | 30 ft (29 ft working) — material conflict flagged in the intro |
| Operation | Power in / power out / freewheel; manual crank backup |
| Braking | Dynamic + mechanical friction |
| Remote | Corded rocker, 9 ft 9 in cord |
| Line speed | ~6 ft/min under load (listing) |
| Weight | ~27 lb |
| Warranty | Not published (sources conflict) |
Pros
- Budget electric with crank backup
- Three-number rating honesty (when read properly)
Watch-outs
- Line-material conflict between listing and manual
- Warranty unresolved
- Amazon-native brand, thin documentation
What owners say: Owner coverage thin in our research — stated, not padded.
Also documented: Powerwinch (no buy button)
Powerwinch’s trailer winches (the 912 and its siblings) are the other established name in this niche — and, as in our other guides, they are covered without a button because our research again verified no Amazon listing for them to this site’s two-source standard. They are dealer-channel buys; the StrongArm above is the buttoned equivalent for brake-first buyers.
Electric boat trailer winch FAQ
Boat weight or line pull — which number do I shop by?
The maker’s own language for that model. Fulton shops by boat weight; Dutton-Lainson publishes a dead-weight pull; Megaflint prints three. The comparison table keeps each in its own words — never convert one brand’s number into another’s currency.
Can I run an electric trailer winch off the trailer battery?
The StrongArm is designed for the tow vehicle’s battery (25 ft harness included). Fulton requires at least 650 CCA and proper gauge wiring. Either way the electrical install is engineered, not improvised — our winch battery guide covers the principles.
Strap or cable for a boat trailer?
Straps (the Fultons) don’t rust, don’t kink and float the hook to you; cable (the StrongArm) tolerates abrasion and heat. Marine corrosion argues strap for most owners.
What size boats do these actually cover?
Maker classes run to 10,000 lb / 26 ft (XLT 10.0). Past that, trailer winching becomes a different conversation — start with our boat trailer guide’s sizing section.
Our verdict
Electric boat trailers, in their makers’ own currencies: XLT 10.0 Powered for most, StrongArm SA9000DC for the brake, XLT 7.0 for mid-size boats, Megaflint on a budget with its paperwork read carefully — and Powerwinch honoured at the dealer counter.
