I started diving my boat a few months ago and take the hull more than or less figured out and tin can practice all my zincs without dropping hardware (that took some iterations of learning). The prop is pretty nasty right now, so I effigy I'll need to become at it with a rotary sander of some type to blast the crap off when it's out of the water next. Once that's done and I drop it back in, what'southward the proper technique for under water preventive maintenance? I drop in once a month or and so. |

Cleaning the Prop - What Tools / Methods ? | 01-12-2010, thirteen:05 | #2 |
| Registered User Join Date: May 2009 Location: Massachusetts Boat: forty' Silverton Aftcabin with twin Crusaders Posts: 1,788 | I wash mine with muriatic acid using an acid brush. The stuff actually cleans upwards most of the growth mess. I recollect this method is OK with bronze props. Mine are copper plated, hydrochloric does non consume copper so I don't worry about it. When finished, I just launder off with a hose. But hydrochloric acrid won't leave whatever residue. My friends utilize an orbital sander which does work. But I don't want to harm the copper plating on mine with a sander. |

If only soft growth I merely utilise a strong brush. Last year I let it become for 3 months in Narragansett Bay and picked up a load of barnacles so went for the metal scraper. If it gets that bad probably should wear some heavy gloves to avoid polluting the h2o with pieces of skin. __________________ |

Not fun, though. If at that place are barnacles on the prop or around, wear gloves, and watch your caput. It is like shooting fish in a barrel to become cut. Chris |

I do non like to utilise metallic implements on a bronze propeller (my prop is bronze, at least), equally steel can scratch the soft statuary. I expect the propeller shape is what the manufacturer wanted it to be, and I'd like to change that every bit lilliputian as possible. For general cleaning I simply apply a white or green 3M nylon scrubbing pad from the hardware store. For scraping hard stuff off I employ a i" x 1" square hardwood stick (viii" is enough to work with) as a scraper. The hardwood is strong enough to scrape off barnacles yet soft enough to not impairment the bronze. The right bending edges of the stick eventually get chewed up and lose a precipitous border, at which point I run the stick through a tablesaw to true up the edges and get them sharp once more. As an aside, to clean the prop while hauled out, running sandpaper over a statuary prop tin can change information technology'southward shape slightly; if you use a fine statuary wire wheel chucked up in a drill you tin can clean the propeller without vehement up the metal. |

Continue the blade abrupt and it makes it easier. I'll so accept some #60, moisture/dry sandpaper to the blade to become the concluding of the barnicles off. All done with a mask and snorkel. __________________ |

Once by that function I used a paint scraper, after that was done I used wet/dry out sand paper. For regular maint I use a ane.v" metal scraper and red scotchbrite pads. |
