    Bad experience

    The part arrived damaged and they made it a pain to get a refund. Took weeks to sort out. I am taking my business elsewhere next time.

    Top notch

    Customer service really helped me identify the right part number over the phone. My outboard is running like it is brand new. Super satisfied.

    Saved my summer

    My boat was down mid-season and they helped me get the parts fast. I was back on the water in less than a week. Really appreciate the help.

    Pretty good

    Used them for a few repairs now. Always get the right part the first time. Prices are fair and the parts are durable enough for my daily use.

    Exactly what I needed

    I was hesitant about aftermarket parts but this is great. It looks just like the original one. No leaks and the performance is just as good.

    Perfect fit

    Bought a complete drive for my boat. Everything was included in the box. Install went smooth with no issues. The boat is back on the water now.

    Reliable parts

    Used their replacement drive for a transom repair. Everything lined up perfectly. Professional team and easy to deal with throughout the process.

    Fast shipping

    My order showed up two days early. Quality of the housing looks good. Saved me a lot of money compared to the OEM price at the marina.

    Okay quality

    The part works fine but the instructions were a bit vague. Took me a few tries to get the shift cable adjusted right. Better manuals would help.

    Decent price

    Good variety of parts for older boats. Found what I needed for a 90s mercury motor. They packaged it well to prevent any damage in transit.

    Excellent service

    Had a question about compatibility and they knew their stuff. The gear case I got is well built and sturdy. Will be back for future repairs.

    Defective part

    Bought a gear set and it failed after two outings. Very disappointed given the work it took to swap it out. Not happy with this at all.

    Fast delivery

    Ordered a water pump kit. Everything was in the package and ready to install. Very easy to find what I needed on their website as well.

    Awesome support

    When the delivery driver lost my box, they sent another one out the same day. Great communication and truly a helpful crew. Highly recommend.

    Great quality

    The casing looks heavy duty. Fit perfectly on my merc cruiser. Nice to have a local manufacturer that makes reliable stuff. I'm a happy customer.

    Helpful staff

    Talked to a rep about a gear ratio issue. They explained the differences well. Part arrived on time and fits my engine without any problems.

    Great alternative

    No need to pay the premium prices elsewhere. These parts do the exact same job. Been using their stuff for three years now without any issues.

    Solid value

    These parts are way cheaper than the dealer stuff. Seems to hold up well enough for my fishing boat. I would definitely buy another part from them.

    Good replacement parts

    Ordered a lower unit for my merc. Shipping was fast and it bolted right up. Only reason for 4 stars is the paint finish could be a bit better.

    Quality gear

    Installed a new unit last month and it has been great. Shifts smooth and runs quiet. Really happy I decided to go with SEI for this project.
