Boat Parts & Maintenance
Buy and sell boat parts and maintenance supplies in Guatemala.
On the Pacific beaches at Champerico and Sipacate, the fibreglass inshore fishing boats that set gillnets run their outboards hard every day, and they get through impellers, propellers and spark plugs at a steady rate. Parts for those motors, new and used, from a water-pump kit to a complete lower unit, are what most owners end up hunting for, alongside antifouling paint, anodes, cleats and the fishfinder off someone’s old boat. Lake and Caribbean pleasure boats need the same consumables, only less often. Before you search, copy the model code off the plate on your motor’s clamp bracket, because that code decides what fits.
Spares for the outboard on a working boat:
they wear out faster than anything else aboard. A Pacific fishing boat runs its motor daily in salt and sand, and the same parts wear out every time: the water-pump impeller, the propeller and the seals in the lower unit. Much of that fleet still runs carbureted two-strokes, so spares for an older Yamaha or Suzuki two-stroke are easier to place than parts for a big injected four-stroke. Complete motors sit under boat engines, and single pieces under boat engine parts. The rest splits by where it goes on the boat. Boat maintenance is paint, anodes and gelcoat repair for the hull. Marine hardware is what gets bolted on, from cleats to steering cables. Marine electronics runs from VHF radios to fishfinders, often taken off a boat before it is sold.
Model codes, shaft lengths and propellers for the highland lakes:
fit comes down to the plate, the shaft and the prop. The model code and serial number on the clamp-bracket plate are what a parts diagram reads, since two motors of the same horsepower from different years can take a different impeller or gasket set. A lower unit or a whole motor has to match your transom height, short shaft or long. A propeller needs the same hub fitting as your gearcase and the right rotation, and its pitch should suit where the boat runs. On Atitlán or Amatitlán the thin air takes a real share of an engine’s power, so a prop with less pitch than the one that worked at the coast lets the motor reach its proper revs. A carbureted motor re-jetted for a highland lake has to be jetted back before it runs at sea level, or it runs lean and overheats. Anodes follow the water rather than the motor: magnesium in fresh lakes, aluminium in salt or brackish water. Antifouling has its own catch, because copper-based paint on an aluminium hull or drive sets off corrosion, so aluminium needs a copper-free formula.
Used impellers, propellers and fishfinders:
the impeller is the one part not worth buying used. Its rubber vanes take a set and harden with age, so one that looks fine can still crack; buy it new and sealed. A used propeller is a different matter. Sight along the blades for bends, feel the edges for nicks, and ask whether the rubber hub has spun, which shows as revs climbing without the boat speeding up. On a lower unit, turn the shaft by hand and feel for play. A fishfinder or chartplotter should be shown powered up with its own transducer and cable, with no sun-clouded screen and no green crust on the connector pins. Fakes turn up in the small consumables: spark plugs, filters and impellers in boxes with blurred printing at prices a genuine part never reaches. Aftermarket makers such as Sierra are a legitimate choice; a box dressed up as Yamaha or NGK is not. With hardware, cheap chrome-plated cleats look like stainless in a photo and pit quickly in salt, so ask whether it is marine-grade stainless and look for bubbling plating under the base.
Listing a spare with its part number:
photograph the number on the bag, box or casting beside the part, and say which motor it came off or fits: maker, horsepower, two-stroke or four-stroke, and the years if you know them. State whether it is genuine or aftermarket, sealed or used, and why the motor was opened. A fisherman in Champerico will want all that confirmed before he gives up a morning to collect a lower unit, since a wrong shaft length sends him home empty-handed. Show the date on a tin of paint and whether it has been opened, and list every cable that goes with an electronics unit. If you are breaking a dead outboard, list the powerhead, the lower unit and the carburetor separately, because each one finds a different buyer.
