Impeller failure - Need to replace tubes

[gth835x]

Impeller failed. Boat overheated and now there are leaks around the hoses that circulate the water to cool the engine.

What are these hoses called and where does the thick hose lead to?

the first pic shows the exhaust hose - readily available - just get the correct ID.

the second shows normal water hoses...the front ones could be molded - can't tell from the pictures.

make sure you understand why it overheated and fix the root cause(s) before just replacing the hoses...unless you want to do it twice....
