Water Pump Leak on '81 Satoh S-630 Bull

[Lane]

Only while the cooling system is pressurized does a small leak appear from the water pump. It is hard to tell if it is from the shaft seal or gasket area. Anyhow, a pump rebuild / replacement may be in order. Any ideas to pinpoint the cause and locate parts would be great and much appreciated.

Check the hose first. Water pump usually leaks when cold it it is the shaft seal and leakes from a weep hole under the shaft. presure leak indicates a hose, gasket or a cracked housing. Most likely a hose.
