It turned up today. I think the dhl guy was a bit shocked, when I waved at the sight of his van. The unit looks great!
So happy with the super quick service, amazed is probably a better term.
One happy customer thank you so much

Hello Hailey.
It’s in, working great and a 1:1 swap with the original.  Nicely done… I could not be happier.
Please let me know if I can be of additional assistance with pics, testimonial, etc.
Very much appreciated..


Awesome Hailey,  thanks,  we like your product,  will plan on ordering all items from you in future instead of from Yanmar….

When we started planning the refurbishment of our 35′ Bertram in Samoa we ran across some parts for our Yanmars that couldn’t be readily found in Samoa, or Australia or New Zealand where we often source parts.  So I begin to search on-line and ran across HDI Marine, finding the part we needed.

I submitted a query about the part, received a quick response, and things rapidly came to shape.  Questions were asked, answered, and before I knew it the Hot1Kit was in FedEx headed to Apia, Samoa.

It was great working with both Hailey and Steve from the time I submitted my initial query and they had the item ready, shipped, and provided a tracking number.

It can be a challenge finding parts for a place like Samoa, let alone having them shipped there from the U.S.   The entire experience went off without any issues or challenges.

Finding customer service like this is a high note, and should be recognized and commended.  From us here in at Troppo Fishing Adventures in Samoa this will always be remembered..

The GMK exhaust kit I received is a truly exceptional product. Thank you for your business.



Our Yanmar exhaust mixing elbow cracked at the beginning of our month long sailing vacation, and we sailed into a local guest moorage. Called HDI Marine, and Hailey got us set up with a 316 stainless replacement, shipped that afternoon FedEx, and we were back out on the water the next day! Hailey knew exactly what we needed, answered all my questions, and we cannot thank her enough! I highly recommend HDI Marine for exhaust components!
