Zebra Mussels Found on our to prevent damage on our 410 FV?

Big story broke on local TV & radio two days ago that Zebra Mussels were found in Lake Travis.  Never had to worry about them before and didn't see any evidence of infestation during when the boat was out of water in February 2017 for a bottom job.

I presume our 410 FV will now require additional regular maintenance to prevent Zebra Mussels from causing damage.  What is recommended to combat Zebra Mussel damage to engines, drives, generator, hull, etc.

Thanks for your input!

    We have both zebra and quagga mussels in Lake Simcoe. From what I've seen so far, not a huge issue unless your boat never moves. I've seen a few small ones on outdrives and I suppose you'd want to check your generator or other raw water intakes once a year, otherwise not an issue. Never seen one on a fibreglass hull.

    Yep, just check metal components and knock em off. I only get them on my outdrive mounts when we pull out in the fall and by spring they are so dry they fall off from a light brushing

    The key is run your engines to temperature at least once a week. That will help prevent them from growing on the inside. The hot water kills them.

    Keep you water intake and filter clean.  They will grow and breed in these areas   Don't forget your gen

    We've had them here on the Mohawk for years, some years better or worse than others. Nothing you can do will stop them, getting off the dock helps but if one attaches 2 minutes after you get back, going out the next day won't blow him off. And when dead they are still stuck. If bottom painted, minimal issue, if not then they can build up in the chine corners. If real bad, your marina will likely charge extra for removal.

    When anchored out and swimming, apart from scrubbing the port side waterline (non dock side) I usually have a look around drives, transom and rams and trim tabs etc with a paint scraper and knock them off or even by hand but note they can be sharp so gloves are recommended.

    Use the boat.  All the lakes have them up here, and they're not the devil that some make them out to be. Lake Ray Roberts has them bad. One of the worst concentrations of them, and it's one of the top fishing lakes in North Texas, and the water is very clean as a added bonus. Just use your boat, and it'll be fine.

    Clean water isn't a bonus.  The Mussels are filtering the plankton out of it (eating it) and in turn, the young fish as fry don't have enough to eat.  They are the devil.  If your boat sits for awhile, they will plug up your impellers, and overheat the engine.  Regular use, and trailering your boat and letting it dry out are the best ways to get rid of them  B)

    Yet every lake here has them, and have for years, and the fishing is great......weird all those young fish don't have enough to eat, but record fish are still being caught. Like I said, use your boat and enjoy the clean water. That's what I've done the entire life of my boat, and I've caught plenty of fish doing it, and zero issues.

    On our Lake Wawasee we used to have a huge problem with zebra mussels.  Then about 15-20 years ago a fresh water sponge was introduced into the ecosystem.  The sponge suffacates the mussles  hence no more or at least very rare to see a zebra mussle on any boat on this lake.  However, this is not the case on some other lakes in our area.  But not on our home lake Wawasee

    We have them on lake simcoe, they are not an issue. My boat sits in the water for 7 months, and when it comes out for the winter all I have to do is clean a few of them off the trim tabs with a light brush.

    100% have your boat hull painted however

    They do clean the water up nice as a side effect

    ++Lake_Bum.  That 'clear water' allows algae blooms and as noted snuff out the bottom of the food chain.

    Thanks for all the info, I'll provide an update regarding any impact when we haul out in the spring for wax and bottom paint check (last repaint 2/2017).
