Why Choose This Yamaha 115HP Outboard Package?
A 115HP four-stroke outboard can be a suitable propulsion option for compatible fishing boats, recreational vessels, and other boats rated for this horsepower range.
This package stands out because it includes a four-blade stainless steel propeller, SeaStar hydraulic steering components, and a Bob’s Action jack plate. For a buyer whose boat is compatible with these parts, having the engine and associated equipment offered together may simplify the sourcing process.
However, compatibility depends on the exact engine model, boat design, transom configuration, steering arrangement, and jack plate specifications. Confirm all measurements and mounting requirements before installation.
Steering, Propeller and Jack Plate Compatibility
The seller lists a SeaStar hydraulic steering system consisting of the ram, helm, and lines. Before purchase, verify that these components are complete, in good condition, and compatible with the exact Yamaha 115HP model.
The included four-blade stainless steel propeller should be checked for pitch, diameter, rotation, damage, and suitability for the intended boat and engine setup.
The Bob’s Action jack plate should also be inspected and matched to the vessel’s transom, engine mounting requirements, setback needs, and load capacity. Professional installation is recommended.
