Can a 2025 Toyota Tundra tow a Grady-White Fisherman 236?
It depends on the engine
We estimate a loaded Grady-White Fisherman 236 on its trailer at about 7,640 lb. 1 of 4 Tundra engine/package options passes with a 20% margin (for example the Capstone (i-FORCE MAX)). 3 are borderline (caution).
Check your exact setup (add your door-sticker payload and real trailer weight)

2025 Toyota Tundra towing ratings vs this boat
| Engine / package | Published rating (lb) | Tow | Payload | Result |
|---|---|---|---|---|
| SR (3.4L i-FORCE) | 8,300 | CAUTION | PASS | CAUTION |
| SR5 / Limited / Platinum / 1794 (3.4L i-FORCE) | 10,890–12,000 | PASS | PASS | CAUTION |
| i-FORCE MAX hybrid (Limited / Platinum / 1794 / TRD Pro) | 10,960–11,450 | PASS | PASS | CAUTION |

"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; Tundra max tongue weight 1,117-1,200 lb depending on cab/drive.
Tongue weight vs payload
Tongue weight should be 10–15% of the loaded trailer: about 764–1,146 lb. That comes out of your truck's payload along with everyone in the cab, so with two adults (300 lb) you need roughly 1,064–1,446 lb of payload before any cargo in the bed.
SR (3.4L i-FORCE) CAUTION
CAUTION 7,640 lb is within the 8,300 lb rating but uses 92% of it, which leaves less than our 20% safety margin.
PASS Needs about 1,064-1,446 lb of payload; the lowest published payload for this engine is 1,810 lb.
SR5 / Limited / Platinum / 1794 (3.4L i-FORCE) CAUTION
PASS 7,640 lb is 70% of the lowest published rating (10,890 lb), inside a 20% safety margin.
PASS Needs about 1,064-1,446 lb of payload; the lowest published payload for this engine is 1,575 lb.
CAUTION Max tongue weight for this truck/hitch is 1,117 lb.
i-FORCE MAX hybrid (Limited / Platinum / 1794 / TRD Pro) CAUTION
PASS 7,640 lb is 70% of the lowest published rating (10,960 lb), inside a 20% safety margin.
PASS Needs about 1,064-1,446 lb of payload; the lowest published payload for this engine is 1,565 lb.
CAUTION Max tongue weight for this truck/hitch is 1,117 lb.
Capstone (i-FORCE MAX) PASS
PASS 7,640 lb is 74% of the lowest published rating (10,340 lb), inside a 20% safety margin.
PASS Needs about 1,064-1,446 lb of payload; the lowest published payload for this engine is 1,485 lb.
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.
