First, we have developed very good relationships with our new boat manufacturers. We buy all of our vessels outright, verses on consignment, which gives us a tremendous price advantage that we can pass on to our customers.

Buying a boat from Diamond Marine in East Haven, Connecticut? Use this guide to evaluate any listing before you commit.
Match the boat to your waters
Pontoons and deck boats suit calm lakes. Deep-V hulls handle chop on larger lakes and coastal water. Center consoles are versatile for fishing. Ask Diamond Marine which models suit the waterways near East Haven, Connecticut.
Inspect the hull carefully
Look for stress cracks, blistering, or repairs on fiberglass hulls. Check the transom for soft spots by pressing firmly — a solid transom feels rigid. Osmotic blistering costs thousands to repair.
Check engine hours
Inboard and outboard engines are typically rated to 1,500–3,000 hours. Low-hour engines with service records are worth more. Ask to see oil change and winterization records for any boat at Diamond Marine.
Request a sea trial
Test the boat on the water before buying. Run it at full throttle. Listen for unusual noises. Check that the throttle and steering respond smoothly. Reputable dealers like Diamond Marine will accommodate this request.
Verify title and registration
Ask for the current title and confirm the hull identification number (HIN) matches. Check for any liens with your state boating agency. Diamond Marine should be able to walk you through the paperwork.
