Engine protective cover

I have the official Yamaha outboard protectice cover, can I leave it on all the time or should it be removed when I am using the rib. It's a 50hp year 2009

Should be removed. The air intake is the slit opening up at the rear top; the cover will impede airflow.

jky

That said, I have seen a few boats running with the covers on. Usually had fenders dragging in the water, too, though.

Thanks, I thought so but also had a feeling it may be purely water cooled.

If you want an engine cover on all the time to protect from sun and elements and even other boats when mooring, try this Making quality outboard motor & marine covers for protection on & off the water. we use them on all boats and they are great

Another big thumbs up for the OCA covers.

We have them on our engines and they not only look smart, they protect the original covers, cut down on the engine noise and clean very easily.

It is water cooled but the engine needs a constant supply of air to efficiently sustain the combustion process
