Re: 70 force not spitting water

Welcome to iboats big dog.

Could be a number of things.

If the key is missing on the impeller, the impeller will just spin on the driveshaft.

Try forcing water up the water tube.

Remove the thermostat and try backflushing the motor with a garden hose.
Replace with a new thermostat.

Saltwater engine? corrosion filled? Sand in the water lines?
