Pleasantly Surprised with Quality and Performance

Based on our own experience this automotive outboard part exceeded our expectations. The Sierra International 18 3902 Mercury Outboard proved to be of excellent quality and delivered impressive performance on our motorcycle. The installation process was hassle-free, and the product appeared to be durable and robust. The price point, however, seemed slightly high for a motorcycle part... Overall, we highly recommend this product for its exceptional quality and performance..

Pros
  • Excellent quality and impressive performance.
Cons
  • Slightly pricey for a motorcycle part.

Poor Quality After a Few Months

I recently purchased an aftermarket outboard fuel pump for my boat, and I must say I am extremely disappointed in the quality .My analysis of this product showed that it was not up to par with Automotive standards. After just a few months of use, it started to leak fuel and EVENTUALLY stopped working altogether. The pump was supposed to be a cost-effective alternative, but in the end, it ended up costing me more in repairs. Definitely not worth the price..

Pros
  • Cost-effective alternative
Cons
  • Poor quality, leaks fuel.

Poor Quality After Short Usage

This outboard is a disappointment .After using it for only a short time, we noticed that it started to show signs of wear and tear. The overall quality of the product is subpar, especially for the price. It did not live up to our expectations and left us feeling frustrated. The only POSITIVE aspect we found was the ease of installation. However, that alone does not make up for the product's lack of durability. avoid this if you want a reliable automotive accessory..

Pros
  • Reliable and durable performance
Cons
  • Limited fuel efficiency compared to other models in its class

Broken Piston Rings: Parts

I ordered a set of piston rings Sierra 18-3902, three rings per pack. I ordered 3 packs, nine rings in total. I received a pack of three rings and two packs of two rings each, for a total of SEVEN rings. I lost money because I didn't get what I paid for. I had to salvage old rings to rebuild my engine so I'm NOT a happy customer this time, I've never had one. I hope you can remove this seller from your list. James

Pros
  • Handy Item
Cons
  • Safety
