A long way back from the far coves
The north end of Lake Lanier has long arms and coves that run far from the main channel. That is part of what makes it a great place to boat, and part of why a reliable engine matters so much there. An engine that quits in a remote cove on a hot afternoon can mean a long wait for a tow. Most of those breakdowns trace back to small things that regular service would have caught: a worn impeller, a weak battery, old fuel or a cracked hose.
Service at your dock or lift
Through mobile service in Gainesville, we can do much of the routine engine work right where the boat lives: oil and filter changes, impeller replacement, belt and hose checks, battery and charging tests, and diagnostics. Boats on lifts and trailers are the easiest to work on. When an engine needs to come apart, it goes to our shop at 6516 Lanier Islands Parkway in Buford.
Overheating
An overheat alarm is one of the most common calls in summer. A raw-water impeller loses its vanes with age, a thermostat sticks, or the intake picks up weeds, leaves or silt in shallow water near the back of a cove. If the gauge starts climbing, throttle back, shut down when it is safe and give the engine time to cool. Check the intake if you can reach it. Then call us before running hard again, because running hot can damage the engine.
Stalls and rough idle
An engine that stalls when you pull back to idle, or idles rough at the dock, often has a fuel problem. Ethanol fuel that sits can absorb water and break down, and a clogged fuel-water separator filter starves the engine. Ignition parts and air leaks are next on the list. We test before we replace, so the fix matches the actual fault.
A yearly service includes
- Oil and filter change.
- Raw-water impeller and cooling flow check.
- Thermostat and gasket inspection.
- Belts, hoses and clamps.
- Fuel filter and fuel-water separator.
- Battery and charging test.
- Steering and throttle check.
Batteries at the dock
A boat that sits at a Gainesville dock all week still has small loads drawing power, like the bilge pump and some electronics. Add a long day at anchor with music running, and a tired battery will not have enough left to start the engine. We test the battery, the charging output and any parasitic drains. A battery switch turned off at the dock and a charger on dock power can help.
Before a long run up the lake
Before heading far from home, check the fuel level, the engine oil, the cooling water flow at idle and the battery voltage. Bring a phone charger, a paddle and the number for a tow service. A few minutes of checking at the dock can save hours stuck in a cove.
What affects an engine job
Pricing is set when you call for a quote. These are the things that change the size of the job:
- Routine service versus tracking down a fault.
- Whether the work can be done at the dock or lift.
- Engine type and access.
- Parts found worn once we look.
Low-hour boats still age
Plenty of Hall County lake-home boats only run a few dozen hours a year. Rubber impellers, hoses and fluids still age on the calendar, so a low-hour boat needs its yearly service as much as a busy one.
