About Tetra Tek Marine
Built by boat lovers, for boat lovers
Tetra Tek Marine is a Downriver marine shop with a simple belief: the comfort and freedom of a higher-end boat shouldn't be out of reach. Based in Wyandotte, Michigan, and serving owners across Michigan and Ohio, we've spent more than 20 years working on boats — so we know how to find solid used cabin cruisers from trusted names like Sea Ray and Bayliner, make sure they're right, and put them within reach for everyday boaters.
Tetra Tek Marine began with one man's love of boats — and a belief that more everyday families deserved a shot at the cabin cruiser lifestyle, not just the wealthy few. To make that happen, he partnered with trusted local service providers and built a genuine full-service shop: one place that finds and sells quality used cruisers, then keeps them running with expert maintenance and repair. It's boating made approachable, backed by people who know these boats inside and out.
Frequently Asked Questions
Answers to your most common inquiries about our marine services.
what kind of boats do you sell?
We specialize in quality used cabin cruisers — including respected names like Sea Ray and Bayliner. Our goal is to make higher-end boating attainable, so you get the comfort of a nicer boat without the new-boat price.
are your boats inspected before they're sold?
Yes. Every boat is checked over and serviced by our own shop before it's listed, so you know what you're getting.
can you sell my boat for me?
Yes — we sell boats on consignment. You stay the owner while we handle the listing, marketing, showings, and paperwork, then take a commission once it sells.
what's your consignment commission?
Our commission is 9% of the final sale price — a notch below the 10% marine industry standard — and you only pay it when your boat sells.
can you service a boat not purchased from tetra Tek?
Yes we are happy to help you maintain and make necessary repairs!
