Yanmar ZT Propeller Set 28 LH + RH KIT ZT-PROP 28
Description
Engineered for maximum top end diesel speeds, Yanmar ZT Propeller Set 28 systems transfer common rail diesel power across an aggressive 28-inch pitch matrix. The counter-rotating dual propeller package accepts 370 continuous horsepower at 3800 input RPM. Heavy stainless steel blades eliminate lateral steering pull while propelling performance express hulls through heavy ocean swells.
Marine-grade stainless steel with mirror polish finish resists seawater pitting and galvanic corrosion across ocean passages. Precision cast blade camber and progressive pitch profiles deliver fuel-efficient high-speed cruising. Integrated rubber drive hubs cushion driveline engagement forces during rapid throttle transitions. Dimensions feature concentric 19-spline and 23-spline drive broaches, polished blade edges, and 38 lbs total shipping weight.
Key Features of Yanmar ZT-PROP 28
Fast boat owners choose to buy Yanmar ZT propeller set 28 hardware when seeking ultimate velocity from twin-turbo Yanmar 8LV diesel installations. This counter-rotating propeller duo attaches straight to Yanmar ZT370 sterndrive lower units.
- A 28-inch pitch rating provides maximum open water speed for streamlined performance hulls.
- Dual counter-rotating wheels capture swirl energy to boost motoring range and reduce fuel consumption.
- Investment-cast stainless steel blade architecture resists flex under peak turbocharger boost pressure.
- Cushioned rubber internal hub sleeves isolate gearboxes from torsional driveline shock loads.
- Hydrodynamic blade profiles suppress cavitation noise to keep cockpit environments quiet at cruise.
- Corrosion-proof metallurgy survives long periods in saltwater moorings without surface oxidation.
- Factory dynamic balancing ensures zero high-frequency vibration enters sterndrive casing bearings.
Maximum Velocity Blade Parameters
The matched 28-inch pitch wheels channel 480 lb-ft of continuous engine torque into 13 kilonewtons of sustained cruising thrust. Progressive blade pitch dynamics allow hulls to maintain high speed planning attitudes at reduced diesel engine revs, saving fuel across extended coastal transits. High blade rake angles lift vessel sterns to improve trim angles and top speed. Thrust energy flows straight into heavy-duty taper roller bearings inside sterndrive lower housings.
Concentric Bore Spline Alignment
Dual hub broaches fit concentric inner and outer propeller shafts with precise 19-spline forward and 23-spline aft interfaces. Shaft centering chamfers hold dynamic radial runout under 0.002 inches across both rotating wheels. Technicians inspect splined surfaces for wear prior to installing retention hardware.
Propeller Anode Service Protocol
Propeller mounting requires torquing the forward propeller nut with a tubular wrench before sliding the aft wheel into place. This propeller group is not intended for non-counter-rotating single sterndrive units or conventional inboards. Routine care maintains propulsion efficiency.
- Check propeller blades for seaweed fouling and hub zinc condition each shift before cast-off.
- Inspect splines for fretting corrosion and coat with waterproof marine grease every 250 engine hours.
- Examine rubber hub shock sleeves for cracks or rotational displacement every 12 months.
Performance Propeller Warranty Manifest
The builder supports this matched propeller package with a 1-Year limited warranty covering materials and hub construction. Crated packaging includes the forward 28-pitch propeller, aft 28-pitch propeller, forward thrust spacer, aft lock washer, and comprehensive technical installation guidelines.
