my little bros 240 with the ka24de overheated because he forgot to turn the fan switch on. everytime we put water in it and run it the top radiator hose keeps popping off. i think he also blew the head gasket. there is no thermostat either. anyone heard of this? what could cause the hose to keep popping off. and we tighten it pretty damn good.

What fan switch? The fan is a hydrostatic clutch fan. You can't switch it on or off. WTF, no thermostat?

Certainly replace the thermostat, upper radiator hose, and head gasket if it's blown. The hose could be popping off because it is burned and very slippery, or more likely because the hose clamp is slipping. Replace the hose and hose clamp, and inspect the radiator nippele.
My upper hose popped off once too, I shortened the hose 1" at both ends, roughed the hose endings with sandpaper to make the hose clamp get friction, and replaced the hose clamps with beefier new ones, and it hasn't slipped yet.
