Sea Trial Checklist

Why Sea Trials Matter Before Every Sale

Flip a Boat buyers evaluate seaworthiness before paying top Cash. PolyCore Games models engine on/off, throttle, trim, and side-panel electronics as functional systems—not cosmetic props—so skipping a sea trial often means lower offers or relisting after failed inspections. Community Discord threads from July 2026 launch week report that first-time flippers lose more margin to skipped pre-sale tests than to bad scrapyard purchases.

Sea trials happen after workshop installs and usually after towing the finished hull to a public ramp on your truck and trailer. Treat the checklist below as mandatory for every flip from eleven-foot skiffs through forty-foot center-console projects with Yamaha XTO or Mercury Verado 350 power.

Pre-Launch Checks on the Trailer

Before backing down the ramp, verify strap tension, winch release, and that the outboard trim is raised enough to clear the bunks. Confirm battery connections if the UI shows helm power. Walk around the hull for loose South Marine parts, dangling wiring, or cosmetic panels that might fly off during launch. These land checks prevent expensive recoveries in busy server waterways.

Open the side panel once on land to confirm engine on/off responds and no red maintenance icons appear while the drive is still dry. If errors show before water contact, return to workshop—launching with known faults wastes ramp time and can add collision repair costs.

• Straps and winch secure; trim raised for ramp angle.
• No loose electronics or cosmetic parts on deck.
• Side panel shows clean status before backing in.
• Fuel or power indicators within expected range if tracked.

Engine On/Off and Idle Test

Launch in calm water when possible. Toggle engine on/off from the side panel—leaks and launch guides confirm controls sit on the side rather than center screen, keeping throttle and trim visible during tests. Let the outboard idle briefly; listen for rough running that might indicate incompatible South Marine parts or incomplete installs.

For twin or quad setups on larger center-console hulls, start one drive at a time if the UI allows, confirming each leg before applying combined throttle. Starter skiffs with single budget outboards still need a clean idle before acceleration tests.

Throttle and Trim Progression

Apply throttle gradually from idle to planing speed. Watch for ventilation, porpoising, or listing that trim adjustments should fix. Use trim raise and lower buttons—highlighted in Discord leak previews—to find stable planing attitude before high-speed turns. Abrupt throttle spikes on first launch are a common beginner mistake that damages drives or gelcoat in shallow areas.

Record mentally which trim settings produced the smoothest ride; repeat them during buyer demo runs if you sea-trial again before sale. Trim mastery also reduces fuel waste during multiple test loops in one session.

Side Panel and Electronics Verification

Cycle installed electronics from the side panel: GPS plotter, fish finder, VHF, stereo, and lighting if equipped. Buyers on premium hulls expect every purchased South Marine item to register as functional. A running engine with blank helm screens still triggers discounts in trade chat even when mechanics are perfect.

If trolling motors or radar appear in future patches per upcoming leak galleries, add them to this section of the checklist when you install them. Until then, focus on launch-week catalog items documented in our items/electronics guide.

Handling Maneuvers at Moderate Speed

Execute gentle turns port and starboard at moderate throttle. Confirm the hull tracks predictably without excessive roll—especially on taller center-console builds. Practice one controlled stop from planing speed to verify reverse and brake response if your layout includes them. Avoid showboating near other players; collision damage erases profit faster than a cautious trial.

If anything feels wrong, return to workshop before listing. Document which parts you replace so the profit calculator stays accurate on the next flip.

Post-Trial Listing Prep

After a clean trial, screenshot helm and side panel status if the game supports it—useful when negotiating with Discord trade buyers. Reload the boat on the trailer with trim up, strap down, and tow home or list from marina UI depending on patch rules. Only then set your asking price using tier list comps minus any cosmetic wear from the trial.

Repeat abbreviated trials after major part swaps even on the same hull. One new outboard or GPS swap can change trim behavior enough to worry buyers.
