Engine: Mariner Shopping experience: Had a wait time to get through on phone. Once connected Alex researched the part i needed. Gasket ended up not being available but Alex spent time to check all resources Repair difficulty: Medium Repair time: More than 4 hours Repair symptoms: No water pump Motor overheated with no water flow. Removed lower unit and found pump in small pieces. Yamaha made the engines for Mariner under 50hp. Parts ID was difficult because sn of 014500 is not even in databases.. Cleaned pump debree from upper pump tube. Pump kit and lower housing seals available but Oil plate gasket is not available and had to make from generic felpro paper. Replace thermostat too which was cooked. Extra time spent researching parts., cleaning With ears and garden hose there was a great water flow On test bench when engine was started
Shopping experience: Excellent, arrived in a couple of days to Australia. Repair difficulty: Easy Repair time: Less than 30 mins
