a few thoughts:
– since you’re paying extra out of pocket for it, this is really more a kind of insurance than it is a true “warranty.”
– the Gold plan only exists as a comparison point for marketing the advantages of the Platinum plan, since the electrical components are so critical in these motors anymore. imho, it’s Platinum or nothing.
– Mercury knows their failure rates at every year of use and prices these plans to cover those costs and still be profitable, that’s as it should be. and yes, the likelihood of a major failure is low…but…if it happens to you, the cost could be quite high.
– it’s a calculated risk based on your ability to tolerate the financial impacts now (100% chance to occur, lower amount) or in the future (may or may not occur, may or may not be a higher amount). so, would you rather pay this insurance cost up front for the surety, or bet that nothing happens and pay more out of pocket down the line if it does? how long do you plan to own the motor?
i’m risk averse, so i recently chose to add the Platinum on mine. i know that most likely this will result in me giving money to Mercury unnecessarily, and i’m okay with that in exchange for the surety.
