Sherwood suggests that impellers be replaced annually, or at least on an annual basis, depending on their use. Nonetheless, it is advisable to inspect them frequently to detect any excessive abrasions or damage. In the scope of preventive maintenance, a new impeller kit is placed every year when the use of your boat is light duty (pleasure boating with low hours). If the use is more intense, or you use your boat in silt and sand, it is advised every six months. When it comes to commercial use, the aforementioned periods are shortened to 6 and 3 months, respectively. Further parts are required to be replaced within your maintenance cycle so as to keep your pump in working condition. A minor kit is needed bi-yearly/yearly for pleasure boating (light duty/severe duty), while for commercial boating, it is required yearly/twice a year (heavy duty/severe duty). Lastly, a major kit is required every 4 years/2 years for leisure activity or every two years/yearly for commercial use. A Sherwood impeller kit is usually made up of an impeller and its relevant installation(s) gasket(s). A minor repair kit includes all the above, plus snap rings and/or a mechanical seal and a wear plate if needed. Lastly, a major kit includes all the aforementioned parts, plus bearings, a cam, and often a water pump shaft. Of course, all these parts are varied as per the intended pump model to repair. Engine overheating is the primary cause of premature engine wear, and any issues with the impeller can result in this.
