Client Experiences
"The team at Idaho Water Sports are the only ones I trust with my Nautique G23. They solved an electrical gremlin that two other general mechanics couldn't figure out. Highly recommend."
"Flawless gelcoat restoration! Sraped our Axis against an iron dock. Garret matched the metallic flake perfectly. You absolutely cannot tell it was ever damaged."
"Their winterization and concierge indoor storage package makes seasonal handoffs completely effortless. They drop the boat off freshly buffed and ready in May."

Routine maintenance such as oil services, impellers and de-winterization is typically completed within 3-5 business days. Larger structural, gelcoat or engine rebuild work is scheduled with a written timeline once diagnostics are complete, so you always know when your boat is coming back.
