Meet Larry

31 Years on the Water — and Still at It

I started out in 1995 as a co-op student at Port Earl Marine and stayed on as a full technician through 2008. After a year detailing boats in Virginia Beach, I came back home to the Blue Water. In 2020 I launched LMB Marine, and I've been running it ever since.

That's three decades of hands-on work on the same waters you run. When you hire me, you get one experienced technician who's seen just about everything these engines can do — and knows how to fix it.

  • 31 years of hands-on marine experience
  • Fully insured — liability coverage on every job
  • Active locally in the Port Huron Boaters community
  • Based in Smith Creek, serving the shoreline

My Promise

Guaranteed for the Season

I stand behind my work. If a repair fails for the same issue in the same season, I come back and make it right at no charge — the only exception being a part you supplied that didn't hold up.

Service Area

Covering the Blue Water Shoreline

Port Huron is home base, and I travel up and down the coast to keep boaters running. If you're near one of these, I can most likely come to you.

Nearby but not listed? Ask — I may still help.

Word on the Water

What Boaters Are Saying

They are professional, knowledgeable, and take the time to make sure everything is done right. Their communication is excellent, and it's clear they take pride in their work and genuinely care about their customers. If you're looking for honest, reliable marine service, I highly recommend LMB Marine, LLC. I'll definitely be recommending them to friends and family!

Melissa Lawrence-Stickler

Larry at LMB marine is very knowledgeable, honest and reliable. I have used him numerous times for repairs on two of my boats. I highly recommend him!

Jeff Bremerkamp

Larry has always been great at providing service when I need it. I use him for my IO engine needs as well as winterization. I highly recommend him.

Frequently Asked Questions

Do you really come to my boat?

Yes. I bring the tools and parts to your slip, lift, or driveway. Most services can be done on-site — no trailering, no haul-out line.

Which engine brands do you service?

MerCruiser, Mercury Outboards, Volvo Penta, OMC, Honda, Yamaha, Johnson and Evinrude — both I/O and outboard. Running something else? Ask.

What's your service area?

Port Huron plus Harrison Township, Grosse Pointe, Lexington & Lexington Harbor, St. Clair, Algonac, Marine City and Lakeport. Nearby but not listed? Reach out.

Is your work guaranteed?

Yes — most work is guaranteed for the season. If the same issue returns that season, I fix it free. The exception is a part you supplied yourself.

Can you work during the off-season?

Definitely. Winter is ideal for bigger jobs like repowers, powerhead work and electrical projects, so you're ready to splash on day one.
