After a period of time, our OMC Outdrive or Sterndrive will lose its original power and workability. Then we have to change it. But finding a suitable OMC Outdrive for our boat model is the toughest thing. The main problem we face here is matching the model and the serial number of its plates.

Because not only SL and model are important here. We also have to find the year of making the boat. For all these problematic things, we need to identify the OMC Outdrive of our boat accurately.

Can You Use An OMC Outdrive if the SL Number is Different?

Once there was a time when the Serial number and Model is different but they could be used in most of the boats. This was for 5.0L and the 5.7L engines of 1988 and also for Ford 5.8 engine. But later this thing changes.

If you are using a boat that is of before 1988 then you may use OMC Outdrive even if they have different serial numbers. But the later versions of your engine may not accept this. In that case, you have to talk with a mechanic who has experience in this sector.


This is the best way to identify the OMC Outdrive you have on your boat. If you are thinking of changing this and replacing this, then try to replace it with the exact matching of model, serial, and also the making year. If you have no prior experience in OMC Outdrive, this might seem a complex process. I think you should not work on this without experience. Take help of an expert.
