Have you ever wondered why jet ski manufacturers don’t put a mesh guard in front of the intake to protect it from sucking up large debris? It would seem so simple, but is it? This is a common question I get from new watercraft owners and often confused such a simple idea hasn’t been done yet.
In this post, I want to go over why jet skis don’t have a complex protective layer in front of the intake grate and why it’s a bad idea to make one. So, let’s dig in and answer the common question people have.
There’s Some Protection
All waverunners have an grate, but it’s more about planing and protecting from very large objects.
There is a whole science behind grates, and the manufacturers design them to offer the most protection without robbing you of too much power.
So, the thing that everyone wants to make is already on there. While it may not look like much and not stop a lot of debris, it’s the best you’re going to get.
The Sea-Doo SAR
Sea-Doo did make an grate that has more protection than a normal, but it’s only on the Sea-Doo SAR.
The SAR is short for “search and rescue” and used by governments and others that fall into similar identities. This is not a normal PWC, it needs to run in harsh environments, so a modified intake grate is used.
While the intake grate on the SAR is better, it’s still not perfect. Sea-Doo also beefed up the wear ring and reinforced in other places. The reason Sea-Doo doesn’t do this with all their watercraft is because it would easily double the price.
Has It Ever Been Done?
There have been a few people who try to make a mesh cover for jet skis or jet-powered outboards.
They all quickly learn it’s not a good idea and see how dangerous it is.
