"When our Wärtsilä engine failed during a critical voyage, PB Asher's team had engineers onboard within 24 hours with the correct OEM parts. Their response saved us $250,000 in potential downtime costs."

"I had fuel problems with the Volvo Penta 63P marine diesel. So I called PB Asher and very quickly Paul responded and was able to, via WhatsApp video, go through possible fault finding issues with the pump. It proved to be locked air in the pump gallery. Thank you so much Paul at PB Asher! From Tim!"

"PB Asher's same-day parts dispatch and detailed compliance documentation have reduced our vessel turnaround time by 40% compared to other suppliers."

"Super service from PB Asher, and specially Max who couldn't have been more knowledgeable, helpful and professional. Clearly a well led company. Couldn't recommend them more. Photo: No those are not brand new, they're what PB Asher turned my old one's into!"

"Volvo Penta injectors were reconditioned in 24 hours. Paul was incredibly helpful in talking me through what was done and why - and all done at a very reasonable price. Highly recommend."

"5 star service from start to finish. I was being told my injectors were beyond repair and being quoted insane prices to replace. PB Asher not only managed to save them they saved me so much time and money in the process. 100% recommend"
