I have a 2014 Yamaha F175XA outboard that has operated flawlessly. However, a mechanic changed the oil and filters and used the flush port to run the engine (yes I now know this was bad). We put it in the water, and the impeller fell apart. I have removed the lower unit, flushed the system both with water and compressed air and have gotten many pieces of impeller out of the engine...and there were many.
The engine overheated and there was no telltale. we pulled the boat/engine and installed a new OEM yamaha impeller kit. But we still cant get the tell tale working and it not to over heat. Here are the symptoms
1. We put the motor in to barrell (no muffs) with water no telltale.
2. We pulled the lower unit and put a hose up to the intake pipr where the water pump housing slides into. The tell tale had healthy flow so no blockage
3. With the lower unit off, a hose connected to the flush connection has perfect telltale flow as well as flow out of the intake.
4. With the lower unit attached, there is no telltale flow when flushing through the fluch attachment.
5. With engine running in the barrel, water is coming out of lower unit in many places but does not seem to getting up to the engine or the telltale
I have looked at the parts diagram and there seems to be a water pump housing part and a seal part that did not come with the impeller kit. I also did not see these parts when we dropped the lower unit for the first time.
I feel like there is not a good "seal" between the lower unit water pump housing and the water tube going into the engine. Any suggestions...anyone? Thansk
