Electrical diagnostics, chartplotters, radar, autopilots, lithium and shore power. I'm Tom Clayholt, and I come to your boat along the Oregon Coast so you don't have to haul it to a shop.
What I work on
Most boat problems these days are electrical: a dead network, a fish finder that drops out, an autopilot that wanders, batteries that won't hold a charge. That's the work Clayholt Marine is built around, plus the mechanical jobs that come with it.
