Propeller and shaft line service in Panama covers prop repair, repitch and balancing, cutless bearing and seal replacement (PSS or stuffing box), and engine-shaft alignment. New vibration almost always comes from a damaged propeller, a worn cutless bearing or misalignment; diagnosing it early prevents transmission and hull damage.
Propeller repair, shafts, cutless bearings, seals and engine-shaft alignment.
Propeller repair, repitch and balancing, shaft straightening and fabrication, cutless bearing replacement, shaft seals (PSS and stuffing box), engine-shaft alignment, vibration diagnosis.
Vibration underway, after striking a submerged object, speed loss or wrong rpm, water leaking at the shaft seal, play or noise in the cutless bearing.
Prop shop with pitch block and balancing equipment, dial-indicator alignment experience, PSS seal knowledge, coordination with the boatyard or a diver.
From $150 (minor propeller repair) to $1,500+ (new shaft or complete shaft line job). Repitch and balancing: $200-$450. Engine-shaft alignment: $150-$400. Cutless bearing or PSS seal replacement: $250-$700 (haul-out billed separately).
The most common causes, in order: marine growth on the propeller, a bent or nicked blade, a worn cutless bearing, or engine misalignment. Start with a diver inspection ($100-$150); if the prop is clean and sound, check the bearing and alignment next.
Not always. A diver can remove the propeller in the water and take it to the shop, and engine-shaft alignment is done afloat. Replacing the cutless bearing or shaft seal usually requires a haul-out, so it pays to combine it with your antifouling.
A standard job (straightening blades, repitch, balancing) takes 3-7 days in the shop. Major damage or 5-blade props can take 2 weeks. If you're on a tight schedule before a Canal transit, ask about express service when requesting quotes.
There's no fixed interval: replace it when there's play. Check it at every haul-out: if the shaft moves more than 1-2 mm inside the bearing or vibrates at certain rpm, it's due. With regular use in tropical waters it typically lasts 3-6 years.
