Engine Mount w/6.85" Footprint - 5/8" Stud - 120-410lbs Capacity Per Mount *** Designed as a rear mount for the Yanmar 4JH series engine The R & D Marine Engine Mounts are designed specifically for the rigors of marine applications. The mounts are stiff enough to absorb forward and reverse propeller thrust, yet soft enough to isolate drivetrain vibrations from the hull. To help increase the longevity of the mounts, all steel parts are zinc plated and pasivated to limit corrosion. The rubber component is covered by an oil shield to protect it from petroleum based products. R & D Marine mounts are preloaded based on the combined engine and transmission weight to limit engine movement. To facilitate in the ease of installation the mounts are height adjusting and the mounting holes in the base of the mount are slotted to assist in alignment of the drivetrain. How To Select (details required): 1.Define the total weight of the engine and the transmission. 2.Determine 60% of the total weight and then divide by 2 to determine the capacity of each of the rear mounts (the mounts on the tranmission side of the engine). 3.Determine 40% of the total weight and then divide by 2 to determine the capacity of each of the front mounts (the mounts opposite the tranmission side of the engine). 4.Determine the stud necessary stud diameter and footprint of the mount. 5.Choose mount most appropriately sized for the per mount weight. When possible, choose the mount nearest the middle of the weight range. Example: Engine weight is 480lbs., transmission weight is 110lbs., footprint is 4", stud diameter is 5/8". Total weight is 590lbs. 590 x .6 / 2 = 177 lbs per rear mount. Mounts required are 800-010 590 x .4 / 2 = 118 lbs per rear mount. Mounts required are 800-037 Why R&D Marine Engine Mounts? Designed for marine use, accepts propeller and engine thrust in both directions Offers a fail safe design R & D Marine Mounts are height adjustable Pre-loaded to reduce movement Slotted holes in base to assist in alignment Mount types to fit all applications

MF 844 Vented Loop - 1" Installing one of our vented loops will ensure that fluids will not siphon from tank to tank. Vented loops are commonly used in the marine toilet system and engine cooling system. The simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through. Molded in Marelon, neither vent nor loop will corrode. The duckbill one way valve is designed to seal properly if particulate matter is present in fluids.  Specifications: Barb Size: 1" (25.4mm) Height: 7" (177.8mm) Width: 9" (228.6mm)
