The Prm 750 Drop-Center marine gear\u2019s dual-shaft design and separate, identical friction plates for forward and reverse operation enable full rated power in both directions. The output shaft (flanged shaft) is 120.6 mm lower than the input shaft. The input shaft has a 17-tooth 16\/32 DP spline.<\/p>\n
Technical specifications:<\/span><\/p>\n The hydraulic system of the gearbox avoids rapid movement of the drive lever to the friction rims and the gearbox reacts quickly to changes of direction, which is important for good boat handling.<\/p>\n Operation and Propeller Handedness<\/span><\/p>\n The gearbox can be used with both clockwise and counterclockwise rotating propellers, making it particularly well-suited for twin-engine installations. The housing is made of high-quality cast iron. The oil pump and hydraulic control valves are mounted externally for easy access.<\/p>\n The gearbox is extremely durable and reliable; it is also equipped with a mechanical locking device in case of a hydraulic failure. In such a situation, the gearbox can be locked in the drive position, allowing the boat to be safely steered back to the harbor.<\/p>\n Operating pressure<\/span> PRM marine clutch<\/p>","protected":false},"featured_media":18337,"template":"","meta":{"_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":""},"product_brand":[],"product_cat":[177208,177355],"product_tag":[],"class_list":{"0":"post-139285","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-merivaihteet","7":"product_cat-vaihteistot","8":"pa_alv-alv-255","10":"first","11":"onbackorder","12":"taxable","13":"shipping-taxable","14":"purchasable","15":"product-type-simple"},"exclude_global_add_ons":[],"addons":[],"yoast_head":"\n\n

Oil Cooling<\/span>
The normal operating temperature of the oil should be 50\u201380 \u00b0C, and the temperature must not be allowed to rise above 90 \u00b0C. An oil cooler is required to maintain the correct operating temperature. The valve block has 1\/2\u2033 BSP connections for installing the oil cooler.
Propeller thrust<\/span>a
Both forward and reverse propeller thrust is transmitted to the output shaft bearings. The force exerted on the bearings is sufficient for all power ratings approved by the manufacturer.
Propeller Free-Spinning<\/span>
The output shaft of the PRM750D marine transmission can be rotated continuously when the transmission is in neutral. For this reason, a propeller shaft brake is not required.<\/p>","protected":false},"excerpt":{"rendered":"
