Shopping experience: Ordered a number of parts for my Yamaha OB. Received all genuine Yamaha parts. Accurate estimate on shipping time and frequent updates. Great service especially considering everything going on with supply and shipping these days. Repair difficulty: Medium Repair time: 2 to 4 hours Repair symptoms: Would not run due to fuel system issues from sitting 5 years Removed and cleaned carb and replaced accelerator pump diaphragm and gaskets. Replaced fuel lines and filter. Replaced fuel pump. Replaced timing belt and spark plugs. Replaced impeller and greased all fittings and cables. Changed lower unit oil and engine oil and filter. Now it sarts on first pull and runs great.
