Help me out here with the price of a boat motor.

That particular motor is damned near a quarter century old, realizing it doesn’t have much time on the engine, but the wiring, hoses, and modules/sensors are 23 yrs old. Personally, I’m thinking whatever you’d need to pay for a new one, take 50% and offer that. Will still need a water pump impeller, service/oil change lower unit, maybe fuel pump, lines, oil lines, spark plugs, etc…

5gs for a 23 year old motor sounds steep how are you verifying only 30 hrs. Super low hours aren’t always a good thing btw

Tiller? Electric start? Tilt and Trim on the hamdle? SS prop?

If all of the above 5k

If not 3k and remove the oil injection as soon as you get it.

Fresh or salt water run?

That motor is 23 years old and harder each day to find part for it when it breaks. Casting alone at that age is starting to have an issue regardless of hours ran. Id not give a penny over $3K-$3500. Its a money pit

Parts availability for the 2003 Yamaha 70 HP (70TLRB) outboard is generally good for maintenance and service items, though some internal, electrical, or major cowling components are becoming obsolete. Popular aftermarket and high-quality OEM parts remain widely in stock.

Very valid point, that is the reason I got a F70Yam over a Tahatsu or Suzuki. The made the jump to the larger frame at 70HP while the Yam did not.
