When a vessel is out of service, every hour counts. That is why, alongside our sales team and engineering support, we have built an online shop that allows you to find and order parts quickly, at any time of day, from wherever you are.
Whether you are a skipper who has just pulled a deteriorated impeller from the cooling system, an engineer working through a scheduled maintenance list or a vessel owner getting ready for the summer, the Watermota shop is designed to get you the right part as quickly as possible.
What’s in the Shop
Our online shop stocks a comprehensive range of marine engine cooling and ancillary parts, with a particular focus on the JMP range that we have carried for many years. The categories include:
- Impellers: flexible impeller replacements across a wide range of engine makes and pump models, held in stock and ready to despatch
- Sea Water Pumps: complete pump assemblies for commercial and leisure applications, including the JMP S76 series
- Spare Parts: pump repair kits, wear parts, and key service components
- Sea Water Strainers: a range of sizes to suit different flow rates and installation requirements
- Accessories: including control cables and ancillary items for the engine room
We regularly review and expand our product range, so it is worth checking back if you have not found what you need previously.
Same-Day Despatch on Orders Placed Before Midday
Speed matters when a vessel is tied up. Orders placed through the shop before midday on working days are despatched the same day. We use reliable overnight carriers, and free UK delivery is available on orders over £100.
One of our customers ordered a pump on a Tuesday afternoon, had it the following morning, and had the vessel back on the water by lunchtime. That is the kind of turnaround we aim for every time.
Competitive Pricing Against the Market
JMP products, and the impellers and pumps we stock, are priced competitively against equivalent Jabsco, Johnson, and Sherwood products. Quality bronze construction, consistent manufacturing standards, and a wide application range make JMP our first recommendation for sea water cooling applications. We are confident on price, and happy to discuss requirements for larger or recurring orders.
Not Sure What You Need? Just Ask
Finding the right impeller or pump for a specific engine can be confusing, particularly on older engines where documentation is incomplete or part numbers have changed over time. Our team is on hand to help. Call us on 01626 830910 or drop us an email with your engine make, model, and year and we will find the right part.
The shop also includes a newsletter signup that gets you 10% off your first order, well worth doing if you are a regular buyer of maintenance parts.
