Tri-County Diesel & Marine Inc

On the day of our planned departure, I found a water pump problem on my Northern Lights genset. The pump was about six months old. I removed the pump and took it to Tri County who cheerfully exchanged it for a new pump. It was a lot easier than I thought it would be and we were on our way the same day

I needed some help with a couple different things for both my generators and mains. Tri-county's staff was very helpful and even though they didn't have the answers right away, they either called or emailed them by the end of the day.

If you want to know your vessel is ready for your next adventure this is your place. Honest, thorough and meticulous describes Mike and the crew. When you want it done right....

Mike and the staff at Tri-County Diesel Marine are fantastic. Their knowledge and attention to detail is unsurpassed. They regularly travel to Alaska to keep their clients operational during fishing season. I have heard that they have even flown to Fiji at the request of a big time diesel manufacturer to keep clients running safely. You will be a regular customer once you try this family business. Plus their new drive-thru is very convenient for picking up the things you need for DIY projects. Good thinking.

I Have had work done by Tri County and they have always been good to deal with.
