  • Stable operation beyond 9,000 RPM
  • Proven in high-performance applications up to 400HP per liter
  • Reduced friction for improved oil flow efficiency

My commercial fishing boat had an issue after 48years and we lost an exhaust elbow. I emailed barr marine and they said they still make those parts, but they don't sell to the public but explained that there are many that sell the parts I was looking for. Your company had most of them and I purchased from another company to get the all parts I needed for the repair. I'm still amazed that I found the parts I needed and that the original company still makes them. Your site was easy to navigate and shipping times were short . Will direct others to find what they need. Thank you.

Nice webpage, easy to negotiate. Thank you for your help!

Very easy . Great price

Thanks

Seems smooth I hope they ship fast

Bought wrong size. How do I return

All good so far

I paid more for 2 day shipping than the product cost, and got it in about 4 days.

Order was as described and arrived fast.
