Mercury/Quicksilver OEM Part Number: 59078

Up for sale is a Genuine Mercury OEM 140° (F) Thermostat to fit the Marine engine models listed. I was not able to find any further fitment info and I am not completely familiar with Mercury parts so please be sure to verify your own fitment before buying. This is a brand new thermostat from Mercury. It was still sealed in the original package from Mercury, but was removed for the photos. No damage or issues. This is the thermostat only as shown, there are no other parts included.   #0.2  YN3-2  7/24

Please look over all photos carefully and ask any questions before buying. Unless otherwise stated, what you see in the photos is exactly what you will receive, nothing more and nothing less. Please be aware that any part number that has been superseded by a new part number may not look or possibly fit exactly the way the part you are replacing does. We only list the superseded part number for reference. Please be sure to click the "Shipping" tab to see all shipping options. In the US, we reserve the right to ship items that have free shipping via UPS/FedEx if the cost is less expensive for us. We do combine shipping, it is based on the combined weight of items purchased. All shipping to the lower 48 states is via UPS Ground Service or USPS. All shipping to Alaska, Hawaii and International destinations will be shipped via USPS. International shipping can be VERY expensive, so please check the shipping cost before buying.

Shipping is expensive and we do not add any shipping or handling costs. We only enter the weight of the item and the dimensions into the description, the rest is calculated by eBay. We will always try to pack as many items together and as inexpensively as we can, we do not like shipping costs either. Local pickup is available with no shipping or extra charges. Thank you for your understanding.

We do have a 100% warranty on all items to be as described. We stand behind all of our items. If there are any problems please do not hesitate to contact us ASAP and we will get them taken care of. We also understand that some items, even if described correctly, may not be what you were looking for or need after all. Please let us know if you would like to return something, even if it is described correctly, we are still willing to accept returns with no problem. For RETURNED items, original "free shipping" charges will be deducted from the refunded price and you, the buyer, are responsible for shipping items back to us.

***International Buyers***
Please Note: We do offer USPS First Class International Shipping as a shipping option. It is less expensive than USPS Priority Shipping, but there is no tracking available and it can take up to 45 days to receive your item(s). This is not normal, very rare, there are usually no problems, but it does happen.

Please be aware that your country may charge import duties, taxes, and charges. These are not included in the item price or shipping cost. These charges are the buyer's responsibility and sometimes will be due at the time of delivery or pickup. Please check with your country's Customs Office to determine what these additional costs will be prior to buying. Thank you!
