Aftermarket Lower Units
There are two options available either to repair your outboard motor after an accident or to replace worn-out parts of the outboard motor. The options are OEM parts and aftermarket parts. Both of the options are good but what kind of parts are best and you want to be used in your outboard motor to get best results. So for this purpose we have made some comparisons, listed below, between these two part types to help you to arrive at right decision.
OEM parts: OEM stands for Original Equipment Manufacturer so it's clear from name that these are the parts directly made by outboard motor's manufacturer and not by third party. So these parts fits to the specification of the model of outboard motor in your use. So these parts provide you the same performance as the replacing ones and provides you a peace of mind, and also most of the manufacturers provide these parts with a one year warranty. But with such benefits there are some cons about them, which are that they are much expensive as compared to the aftermarket parts. Although there are many other ways to buy them, like (eBay, online wholesalers), but most of the people will buy them from the dealer because it takes longer to get your outboard motor repaired by ordering them online, thus limited number of places you can buy them from. And you have paid more for OEM parts doesn't mean that they are better than aftermarket parts, sometimes aftermarket parts are equal to OEM parts or even better in some cases. So you might pay extra only for the brand name.
Aftermarket parts: Those parts for the outboard motor which are supplied by manufacturers other than your outboard motor manufacturer are called as aftermarket parts means parts which are sourced from third party. They are manufactured at a high volume and may fits to the requirements of different models of outboard motor, not the specific make or model. They are similar to OEM parts in kind but may not be perfect for use. So you should deal with right mechanic to provide you with high quality parts. But they are much cheaper than OEM parts and sometime you may get a better quality part. In this case you have more variety to choose from and wider price range as many manufacturers are making same thing. But to keep cost down they may not come with warranty.
