Greasing the Max-Prop once a year is ideal under most conditions. This can be done either with the boat on land or by a diver while it\u2019s in the water. Regular greasing ensures a longer lifespan for your propeller. At a minimum, greasing should be performed every two years to maintain efficiency and reduce wear.<\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”What grease should I use for the propeller?” _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}” open=”off”]\n
We recommend using Lubriplate<\/span> 130AA<\/span><\/a> due to its proven performance in a wide range of water temperatures. Alternatively, Lewmar winch grease<\/em> can be used, especially in warmer climates.<\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”How long do the anodes last?” _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}” open=”off”]\n Anodes<\/a> (zinc or aluminium) can last anywhere from two weeks to two years, depending on the galvanic activity on your boat and the surrounding water conditions. For new installations, check the anodes regularly to monitor their wear rate. To be safe, replace the anodes during every haul-out as a cost-effective way to protect your equipment.<\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”Do I need a shaft zinc, or is the propeller zinc sufficient?” _builder_version=”4.27.3″ _module_preset=”default” body_link_font=”||||on||||” body_link_text_color=”#0089A1″ global_colors_info=”{}” open=”off”]\n It\u2019s always better to have additional zinc for protection. The Max-Prop three-blade has a built-in zinc anode, particularly useful in installations with limited space. If your propeller shaft is supported by a strut, adding a shaft zinc is strongly recommended.<\/p>\n[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.3″ _module_preset=”default” header_2_font_size=”24px” global_colors_info=”{}”]\n In optimal conditions\u2014calm waters, a clean hull, and a well-maintained propeller\u2014your engine should reach its maximum rated RPM.<\/p>\n Adjust the blade angle during your next haul-out to correct these issues.<\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”My engine isn\u2019t reaching the maximum RPM. How much should I adjust the pitch?” _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}” open=”off”]\n To increase the maximum RPM, reduce the blade angle setting. A two-degree decrease in blade angle typically raises the RPM by approximately 13%. This adjustment ensures your engine operates efficiently and prolongs its lifespan.<\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”What is the correct procedure to feather my Max-Prop?” _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}” open=”off”]\n Feathering depends on your transmission type:<\/p>\n Yes, the Max-Prop can be repaired or reconditioned to address damage such as pitting, bent blades, or normal wear and tear. Contact us<\/a> for a a reconditionning request.<\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”Can the Max-Prop be installed or maintained in the water?” _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}” open=”off”]\n Yes, the Max-Prop Easy can be installed both in and out of the water. Routine maintenance tasks, such as greasing and replacing anodes, can be performed by a diver while the boat remains afloat, making it convenient for ongoing care.<\/p>\n[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.3″ _module_preset=”default” header_2_font_size=”24px” global_colors_info=”{}”]\n Several products can help reduce marine growth on your Max-Prop. One of the most effective options is Crystal<\/span> Prop<\/span><\/a>, which costs around 80\u20ac per application. While no product is entirely foolproof, when applied correctly, it can last an entire season. However, frequent use of the propeller will cause antifouling coatings to wear off more quickly.<\/p>\n[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.3″ _module_preset=”default” header_2_font_size=”24px” global_colors_info=”{}”]\n The Max-Prop can operate in either direction. Determine the rotation by viewing the shaft from the stern of the vessel:<\/p>\n For a two-blade propeller, measure the distance from the tip of one blade to the tip of the other. For three, four, or five blades, measure the radius (centre of the propeller to the tip of one blade) and double that measurement to find the diameter.<\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”Can the Max-Prop drive a shaft alternator or regenerate an electric motor?” _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}” open=”off”]\n Yes, if you shut off the engine with the propeller in reverse, it will not feather, allowing the shaft to rotate. This rotation can drive a shaft alternator or be used to regenerate power for an electric motor.<\/p>\n[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.3″ _module_preset=”default” header_2_font_size=”24px” global_colors_info=”{}”]\n Several products can help reduce marine growth on your Max-Prop.

Follow the same steps as above. The remaining hydraulic pressure usually provides enough drag for feathering.<\/li>\n
These systems may default to neutral, reducing drag and making feathering more challenging. For these, consider using a Max<\/span>-Prop<\/span> Boomerang<\/span><\/a>, which uses spring-loaded blades for consistent feathering.<\/li>\n<\/ul>\n[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.3″ _module_preset=”default” header_2_font_size=”24px” global_colors_info=”{}”]\nInstallation and Repairs<\/strong><\/h2>\n[\/et_pb_text][et_pb_accordion open_toggle_text_color=”#19283F” closed_toggle_background_color=”rgba(255,255,255,0.5)” icon_color=”#19283F” use_icon_font_size=”on” icon_font_size=”24px” _builder_version=”4.27.3″ _module_preset=”default” toggle_text_color=”#19283F” toggle_level=”h2″ toggle_font=”|600|||||||” toggle_font_size=”18px” body_link_font=”||||on||||” body_link_text_color=”#0089A1″ border_radii=”on|5px|5px|5px|5px” box_shadow_style=”preset3″ global_colors_info=”{}”][et_pb_accordion_item title=”Can the Max-Prop be serviced and repaired?” open=”on” _builder_version=”4.27.3″ _module_preset=”default” global_colors_info=”{}”]\n
