When your generator stalls with the AC running, it’s load, sizing, or cooling, not always a failing unit. Here’s how we tell the difference.

A corroded exhaust elbow restricts flow and can flood cylinders with raw water. Here’s how it fails, the symptoms to watch, and when to replace it.

Warm bay water shrinks your cooling margin. Here’s why a diesel that ran cool in spring creeps up in summer, and what to check before it overheats offshore.

Marine generators sit harder than propulsion engines and fail more often in the first month of the season. Here’s why that pattern shows up every April, and what to check before it ruins a weekend.

Mobile service is the right call for some jobs and the wrong call for others. Here’s how we think about it when an owner phones in, and what the honest trade-offs look like.

Commercial fishermen figured out a long time ago that waiting for a problem to show up on a gauge is a bad economic model. That approach is worth looking at for recreational boats too.

A boat that ran fine in October can overheat within twenty minutes of its first spring launch. Here’s what we check on the raw water circuit before we let anyone turn the key.

Five months of winter storage does something specific to the fuel in your diesel tank, and what happens in April if you ignore it costs a lot more than a filter change.

A marine diesel repower is much more than simply swapping out an old engine for a new one. It is a detailed, multi-step process that involves evaluating your entire vessel, upgrading key systems, and ensuring everything works together for optimal performance.
