Used 2000 Yamaha F100TLRY 100 HP 4-Stroke Outboard Motor

Used 2000 Yamaha F100TLRY 100 HP Four Stroke 20 Outboard Motor For Sale


For sale a good used 2000 Yamaha 100hp four stroke. This has trim and tilt and electric start. This is a four stroke , carburated, long shaft (20") motor. We got this motor with a engine noise so we disassembled it and found a bad crank bearing, we installed new bearings a good used crankshaft. 


we disassembled the mid section to clean out oil pan for any metal shaving. this also has a new head gasket and everything has been checked over. from the looks of the cylinder walls I don't think there is many hrs on this motor. We have checked this over and made it water ready.


We have removed the carbs and cleaned and synchronized. We installed a new water pump impeller, pressure and vacuum tested the lower unit, filled with new gear lube. Performed a leak down test and found all cylinders were at less than 3% which is excellent. A leak down test measures the percentage of air leaking past the piston and rings, this is more accurate than a compression test. On the leak down tester there is a gauge that reads 0-100%, 0% being the best and 100% the worst, typically most motors have some percentage of leak, but your looking for as close to 0% as possible and typically anything over 20% that cylinder will not run right or if there is a big variance in the cylinders.


This motor is overall in great shape and will make someone a good motor.
