Long off-seasons in the hills
Many Dahlonega boats spend more months in storage than on the water. A long, cold off-season in a barn, garage or lot is hard on an engine that was not put away right. Fuel breaks down and leaves varnish, batteries go flat and can freeze, rubber parts stiffen, and mice sometimes move into the engine compartment and chew wiring. The first start in spring is when all of it shows up.
A good fall layup and a careful spring wake-up prevent most of these problems. When they do happen, we find the cause and fix it before your first trip down to the lake.
Spring wake-up
- Check for chewed wires and nests in the engine bay.
- Charge and test the batteries.
- Change the oil and filter if it was not done in the fall.
- Replace the fuel-water separator filter.
- Inspect belts, hoses and clamps.
- Check the impeller and run the engine with cooling water.
Hard starts and rough running
If the engine cranks slowly, the battery or connections are the usual suspects. If it cranks fine but will not catch, or starts and stumbles, look at fuel and ignition. Old fuel is one of the most common causes after a long storage season. We test before we replace parts, so you pay to fix the real problem.
Overheating at the lake
A boat that has sat all winter may run hot on its first trips. The impeller vanes may have taken a set, the thermostat may stick, or debris may be blocking the intake. If the gauge climbs, throttle back, shut down when safe, let it cool and call us before running it hard again.
Where we do engine work
Through mobile service in Dahlonega, we can do much of the routine work where the boat is kept. Engine repairs that need a bench or more time come to our shop at 6516 Lanier Islands Parkway in Buford. Many owners drop the boat off on a lake weekend, so the trip does double duty.
Running the engine on the trailer
Never start a raw-water-cooled engine on the trailer without water to the cooling system. The impeller can be ruined in seconds. Use proper muffs or a test tank and keep it at idle. We bring what we need to run engines safely on site.
Keeping critters out
Rodents love a quiet boat in a barn or garage. Close up openings where you can, keep food off the boat, and check the engine bay before the first start. Chewed wiring can cause no-starts, odd gauge readings or worse.
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.
- Where the work can be done.
- Engine type and how easy it is to reach.
- Parts found worn once we look.
Fuel for long storage
If the boat will sit for months, fill the tank and add stabilizer before storage, then run the engine long enough to get treated fuel through the system. A full tank leaves less room for moist air.
Low hours still need care
A boat that runs only a few weekends a year still needs yearly service, because impellers, hoses and fluids age on the calendar.
