Inboard marine · Lake Lanier

Inboard marine.

Inboard engines serviced, winterized and swapped on the trailer, at your driveway, lot or boat ramp around Lake Lanier. The crane that pulls a V8 out of a Camaro lifts one out of a ski boat the same way.

On the trailer

The boat stays on its trailer.

Service happens where the boat sits: tune-up, raw-water impeller, oil, filters and fluids, all done on the trailer. For a swap, the crane does the lift. The inboard V8 comes out, the replacement is set, aligned and run.

It is the same rig and the same book-hours pricing as the automotive work, $145 an hour, with the quote itemized before anything is booked and the invoice itemized the same way after.

Inboards only

Inboards. No outboards.

Seven Heavens works on inboard engines only, never outboards. And when the hull wants a new look, boat wraps are part of the vinyl line: color changes and graphics for ski, wake and cruising inboards, priced by the boat's length.

Off-season and back

Winterize. De-winterize.

Going into the off-season, the engine is drained, fogged and stabilized. Coming back for the lake, it's filled and made ready. Either way it books at 2–3 hours plus antifreeze and supplies, from $370.
