1994 yamaha 250 outboard..txrs

I run boat in drive way and I got an overheat alarm. Work fine last time out. The boat is relatively new to me so I don't know the maintenance it's had. Thermostats and poppet valve are changed. I dropped lower unit and this is what I found

Were the small hose attaches is broken and now so is the bolt

Lucky you found this out on land. Did the pump run dry before it alarmed? Did you run the motor on muffs or in a tank?

Someone / seller ran the motor with no cooling water to the pump.----Simple as that.

I had it hooked to muffs...so how about that other white peice. I cant seem to find it anywere online

 

[racerone]

Seller likely demonstrated motor a number of times without water to the impeller.----That is done all the time !----The white piece likely has something to do with speedometer hose.
