Can a 2026 Toyota Tacoma tow a Key West 189 FS?
It depends on the engine
We estimate a loaded Key West 189 FS on its trailer at about 3,480 lb. 3 of 4 Tacoma engine/package options pass with a 20% margin (for example the XtraCab, i-FORCE (non-SR)). 1 is borderline (caution).
Check your exact setup (add your door-sticker payload and real trailer weight)

2026 Toyota Tacoma towing ratings vs this boat
| Engine / package | Published rating (lb) | Tow | Payload | Result |
|---|---|---|---|---|
| SR (2.4L i-FORCE) | 3,500 | CAUTION | PASS | CAUTION |
| XtraCab, i-FORCE (non-SR) | 6,500 | PASS | PASS | PASS |
| Double Cab, i-FORCE (non-SR) | 6,400 | PASS | PASS | PASS |
| Double Cab, i-FORCE MAX hybrid | 5,950–6,000 | PASS | PASS | PASS |
"Published rating" is the lowest–highest conventional (ball-hitch) rating Toyota prints for that engine/package across cab, bed, drive and axle choices. PASS means the loaded trailer is at or under 80% of the lowest rating. Toyota: ratings per SAE J2807; payload includes occupants, cargo and options.
Tongue weight vs payload
Tongue weight should be 10–15% of the loaded trailer: about 348–522 lb. That comes out of your truck's payload along with everyone in the cab, so with two adults (300 lb) you need roughly 648–822 lb of payload before any cargo in the bed.
SR (2.4L i-FORCE) CAUTION
CAUTION 3,480 lb is within the 3,500 lb rating but uses 99% of it, which leaves less than our 20% safety margin.
PASS Needs about 648-822 lb of payload; the lowest published payload for this engine is 1,230 lb.
SR is limited to 3,500 lb.
XtraCab, i-FORCE (non-SR) PASS
PASS 3,480 lb is 54% of the lowest published rating (6,500 lb), inside a 20% safety margin.
PASS Needs about 648-822 lb of payload; the lowest published payload for this engine is 1,230 lb.

PASS 3,480 lb is 54% of the lowest published rating (6,400 lb), inside a 20% safety margin.
PASS Needs about 648-822 lb of payload; the lowest published payload for this engine is 1,380 lb.
PASS Max tongue weight for this truck/hitch is 640 lb.
Double Cab, i-FORCE MAX hybrid PASS
PASS 3,480 lb is 58% of the lowest published rating (5,950 lb), inside a 20% safety margin.

Confirm with your door-jamb sticker and owner's manual. Your exact truck's rating depends on cab, bed, drive, axle ratio, options and tires, and your boat's real weight depends on its engine, options, fuel and gear. When in doubt, weigh the rig at a CAT scale.
Gear you may need
Placeholder links (not affiliate links yet). Disclosure.
Trailer brake controller
Boat trailers over about 3,000 lb usually need working trailer brakes (check your state's law); an electric-over-hydraulic or electric setup needs a controller in the truck.
Class IV receiver hitch & ball mount
Match the ball mount drop to your trailer so the boat rides level; the hitch rating must cover the full loaded trailer.
Tongue weight scale
The only way to know your real tongue weight (10-15% of the loaded trailer) before it eats your payload.
