Growth Never Waits in Miami
Step off the dock in Miami and marine growth is already working against you. Barnacles, slime, and algae don’t need weeks—they need days. Warm water, constant sun, and a steady flow of nutrients turn every propeller and shaft into prime real estate for marine hitchhikers. Ignore it, and you’ll see speed drop, fuel bills climb, and vibration rattle the helm. Props lose their edge. Shafts pick up drag. The boat feels sluggish, and the engine works harder for less.
Saltwater doesn’t just feed marine life. It chews through metal. Corrosion sets in fast, especially when growth takes hold. Saltwater damage can quickly escalate. Props pit. Shafts stain. The longer growth stays, the deeper the damage. Ignore it, and you’re not just cleaning barnacles—you’re replacing hardware.
What Growth Does to Your Running Gear
Growth on props and shafts isn’t just ugly. It throws off balance. The prop spins unevenly. Vibration creeps up the shaft. Bearings wear out. Seals start to leak. The engine strains. Fuel use jumps. Top speed drops. You feel it every time you throttle up. The boat doesn’t leap onto plane. It lumbers. That’s marine growth at work.
- Props lose their bite. Acceleration fades.
- Vibration shakes the hull. Fasteners loosen.
- Corrosion eats into metal. Pitting and staining follow.
- Seals and bearings wear out early. Leaks start.
- Fuel economy tanks. Trips cost more.
Let growth sit, and you’re not just cleaning. You’re fixing what’s broken.
Real Protection That Works
Antifouling coatings have changed the game. The top prop and shaft coatings use slick polymers and biocides. Barnacles can’t grip. Algae slides off. When applied by our marine technicians, these coatings last the season. No missed spots. No shortcuts. The surface stays smooth. Growth can’t get a foothold.
Zinc anodes do more than fight corrosion. They change the chemistry around your running gear. Barnacles avoid it. Growth slows down. But zincs wear out. Miss a replacement, and you lose the shield. Regular checks keep the protection strong. No guessing. No surprises.
- Premium antifouling paint for props—slick, tough, and proven
- Silicone-based shaft coatings—nothing sticks, not even slime
- Correctly sized zinc anodes—placed where they matter
- Routine cleaning—no buildup, no hidden damage
- Underwater inspections—catch problems before they cost you
Protection isn’t one-size-fits-all. Boats that run every weekend need more frequent checks. Dock queens need coatings that last. Seasonal maintenance planning keeps you ahead of the curve. No missed steps. No wasted money.
Why DIY Falls Short
Scraping barnacles with a putty knife feels satisfying—until you see the scratches. DIY cleaning misses the tight spots behind the prop hub and around the shaft collar. Growth hides there. Miss it, and it comes back faster. Harsh scrubbing strips away coatings. The next round of growth sticks even harder. DIY attempts often miss critical areas and leave you with more work next time.
Professional marine techs use the right tools. Soft pads, not metal scrapers. Underwater cameras to check every inch. They know where growth hides and how to remove it without damaging the surface. They spot early signs of corrosion and swap out zincs before they’re gone. The job gets done right, and the protection stays intact.
- DIY: Missed spots, scratched coatings, faster regrowth
- Professional: Full coverage, no damage, longer-lasting results
- DIY: No inspection, hidden corrosion, surprise repairs
- Professional: Early detection, quick fixes, no surprises
Cut corners on maintenance, and you pay for it later. Let pros handle the tough jobs. You get more time on the water and fewer headaches at the dock.
Routine That Keeps Growth Away
Growth never takes a break. Your maintenance can’t either. Set a schedule and stick to it. Monthly checks in summer. Extra cleaning after long trips. Replace zincs before they’re half gone. Don’t wait for vibration or a drop in speed. By then, the damage is done.
- Inspect props and shafts every month—look for slime, barnacles, and pitting
- Clean running gear before buildup gets thick
- Check zincs—replace when worn, not when gone
- Touch up coatings as needed—don’t let bare metal show
- Book professional service before the season starts and after heavy use
Stay ahead of growth, and your boat runs smoother, faster, and cheaper. Ignore it, and you’re fighting a losing battle every time you leave the dock.
