JLM Marine Boat Parts Limited Coupon Codes & Deals

JLM Marine Boat Parts Limited is an aftermarket manufacturer of parts for outboard and inboard marine engines, selling online at jlmmarine.com with prices in USD. The brand describes itself as "factory-direct" and says it has been making marine parts since 2002, with a catalogue it puts at more than 7,000 parts — figures the company states about itself rather than independently confirmed ones. Parts are built to fit engines from Yamaha, Mercury, Johnson/Evinrude, Suzuki, Honda, Tohatsu/Nissan, Volvo Penta, and MerCruiser. The factory is in China, production runs in what the brand says is an ISO9002-certified facility, and its customers are individual boat owners and repair shops.

Cooling-system kits are the core of the range. The Water Pump Impeller Repair Kit for Johnson/Evinrude V4/V6/V8 90-225 HP outboards is listed at $35.00 on sale against a $49.50 regular price, and the Water Pump Repair Kit for Mercury/Mariner 75-115 HP outboards sells at $89.00, down from $103.00. Beyond cooling parts, the store carries fuel-system components such as the VRO Fuel Pump Replacement Kit for Johnson/Evinrude 90-115 HP V4 engines at $73.50 (regular $88.00), plus oil filters, electrical parts, engine accessories, decal sticker sets, and trailering gear. Product pages we checked list a 1-year warranty against manufacturing defects under normal use.

On shipping, the brand publishes two statements that do not agree: its shipping policy page says "Free shipping. No Minimum Purchase," while its Johnson/Evinrude collection page says free shipping applies to "orders under 2kg." JLM Marine does not reconcile the two, so treat the no-minimum claim with care — many items are charged weight-based shipping, rounded up to the nearest pound. The brand says it "can ship to virtually any address in the world," quoting 1-5 business days for US and Canada orders fulfilled through Amazon FBA, about 7 days from its US warehouse, and around 12 days from its China warehouse, with most orders leaving the warehouse within 24 hours. Returns run 7 calendar days from delivery (14 days for EU customers); items must be new, unused, and in original packaging; a 20% restocking fee applies to change-of-mind returns; and original shipping charges are not refunded. The process goes through email: request an RMA within 7 days, ship the item within 3 business days, and refunds are issued within 10 business days.

On discount codes: the brand's own public code WELCOMEJLM takes 10% off and is limited to new customers, which makes it stronger than our 8% STACKWELLPICK19 code — if this is your first order, use WELCOMEJLM; STACKWELLPICK19 is the one returning customers can still apply. JLM Marine does not publish an expiry date, minimum order, or exclusion list for either code. It also does not publish a standalone warranty page (the /pages/warranty URL returns a 404), the specific exclusion conditions of its 1-year warranty, which products are restricted from international shipping, or what shipping costs apply to orders that fall outside its free-shipping terms.
