About

Can you tell me when my SEI drive was made from its serial number?

Yes - send us the 6-digit serial from the red tag and we can look up when it was sold and confirm the ratio it was built with. For context on age, we're currently shipping drives in the 300,000-plus serial range, so a five-digit number is a genuinely old unit. Records for the oldest units are held separately, so those can take our warranty department a day to retrieve.

How many units has SEI sold?

We've sold more than 300,000 units over the years, and we've been in business since 2004. Any mechanical device will have some failures across that volume, which is worth bearing in mind when reading mixed reviews online - it's also why we back them with a 3-year fault-free warranty and free technical support.

Dealer

Are you the manufacturer, or a reseller?

We're SEI - we manufacture these units, so everyone else who sells them gets them from us. Pricing on sterndrive.cc is in US dollars; our European operation at seimarine.eu is priced in euros. If an order is shipping to Canada or elsewhere outside the US there may be duties and taxes collected on your end when it's delivered.

Can I use my own FedEx account number for shipping?

It isn't something we normally do, simply because with the number of dealers we have it would become unmanageable if everyone did. We have made exceptions: order online, choose local pickup as the shipping option and put your FedEx account number in the order notes. That's for orders shipping directly to you only - not drop shipping to your customers.

Do you have a stocking distributor near me?

We have dealers all over the country, but none of them keep stock - they order from us and we ship it out. That means the quickest route is almost always to order directly from sterndrive.cc, where you'll see the FedEx shipping options and prices at checkout. If you're in a hurry, in-stock items ordered before 3pm ET ship the same day.

How do I become a dealer or distributor?

Scroll to the bottom of any page on sterndrive.cc and click the "Become a Dealer" link, then follow the directions there. That kicks off the process with our team.

How do I become an SEI dealer or distributor?

Start at the "Become a Dealer" link at the bottom of any page on sterndrive.cc and complete the dealer application form there. Send the completed form back to us and it goes to our team for consideration. If you're mid-job you don't have to wait - you can order without a dealer account and get the application processed in parallel.

Is there a minimum order for dealers, and when is shipping free?

There's a minimum order value, and orders above a set threshold ship at no charge - dealer terms differ from retail, so ask us for your account's current figures. The exception either way is large items such as lower units and transom assemblies, which are priced by their size and weight. Shipping on a 30" unit in particular runs higher because of the box dimensions.

Which dealer near me stocks your drives?

None of our dealers hold stock - they order from us and we ship. So the quickest and simplest route is to order directly from sterndrive.cc, or call us at 813-925-7127 and we'll take it over the phone. In-stock items ordered before 3pm Eastern ship the same day.

Why does the dealer application ask for credit card information?

We only ask for the last four digits - it's simply a record of which card you want associated with the account, not an auto-billing arrangement. Every order is paid for before it ships, and we collect the full card details on your first order.

Location & Hours

Where is SEI Marine located?

Manufacturing

Where are SEI units made?

Our units are assembled in our own factory in Taiwan and ship out of our facility in Florida. They're built to be as strong as or stronger than the original equipment, which we verify through testing at our private test lake here in Florida. Worth noting that when you disassemble as many OE gearcases as we do, you find they're largely built from overseas-sourced parts too, even when final assembly happens domestically.

Product Range

What kinds of products do you actually make?

We manufacture outboard lower units, sterndrives and the related parts - gearcases, transom assemblies, trim and tilt systems, seals, water pumps, bearings and tooling for those applications. We don't make parts for other kinds of engines or vehicles, so if a part number looks similar but is from another machine entirely, it won't cross over. Tell us the engine you're working on and we'll tell you honestly whether it's something we cover.

Quality

Are your parts made to the same specification as the original?

Everything we manufacture is inspected to be an accurate reproduction, right down to X-ray inspection to confirm the materials match the OEM material. Every unit is built, pressure tested and manually shift-checked before it ships. Our drives were designed around the OEM drives and then tested against them on our own research lake. Our Google reviews run 4.8 out of 5.

I've read your lower units are noisier than the original - is that true?

We don't find that to be the case. We test our units against the OEM units, most of the time to the point of failure, and we spend hundreds of hours doing it at our test lake here in Florida. A brand new unit is louder than a worn-in one until the gears bed together, which is what most people are hearing in the first few hours - it should quiet down after proper break-in.

Support

Do you have Spanish-speaking staff?

Yes - we regularly handle enquiries in Spanish by text and phone, including part identification from photos. Text us at 813-925-7127 in whichever language you're comfortable with.
