Engine: Yamaha F115TLR Shopping experience: Crowley Marine is my go to place for parts. I seem to acquire outboards that are broken or don’t run and use Crowley to help me out. Repair difficulty: Hard Repair time: More than 4 hours Repair symptoms: Gas in oil During a boating trip my 2006 Yamaha 115 4 stroke quit. No alarms, no warning. Took it to a dealer and they said water in oil. No doubt and the engine was junk. The boat yard put a new 115 Mercury 4 stroke on my boat and I decided to take the Yamaha home to take apart and see why it failed. It was assumed that the adaptor plate corroded and water leaked into the oil pan. When I took the motor apart the was no corrosion anywhere. I questioned water in the oil and spoke to several outboard mechanics. One thought that gas could be leaking into the oil pan through the cylinders due to a faulty thermostat. I had a laboratory analyze the oil for water content. Gas in the oil was much more costly to determine. The lab result was no water so the only other source was gas. Bottom line, the boat yard mechanic totally missed diagnosed the problem resulting in a very costly new engine. It appears that a simple $60 thermostat and an oil change and filter would have solved the problem. I have received all the parts from Crowley Marine and I am now in the process of putting the Yamaha back together. When its completed I will follow up on the outcome.
