Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
Waterpump on these are not the same as a normal boat engine, these use venturi on the jet pumps. The lines can get clogged with sand and water not coming out does not mean it is not getting water and cooling. Thus the system would need to be checked and try back flushing the system to remove any restrictions. Next not that corrosion such as in the head can cause problems as well.
Sometimes an air hose can remove a restriction as well as back flushing but that in some cases it's best to let someone experienced do it as damage can be caused.
If you can provide the year, make and model I'd be happy to provide diagrams of the system.
Thank you!
