Dealer Engine Prep

Validates warranty. Includes filling oil, completing a full OEM checklist, test run in tank, drain fluids, quart/s of oil added to crate, recrating. Assures a working engine.

Pre-Delivery Inspection

Standard Fee for services performed & products used on each new vessel, requested by all manufacturers to validate and assist in all warranties.

We install a deep cycle marine battery, fully rig steering components, complete electrical and systems check. We conduct a full system check on the motor, fill with oil, fluids, and fuel, then test run in a test tank.

Once everything is tuned and prepared, a sea trial is performed with two Specialists to achieve ideal RPM-to-top-speed ratio, ensuring the boat gets on plane properly, and all systems operate on water.

Afterwards a full detail is performed on the tubes, deck, and hull to be turn-key ready for the customer.

CA DMV Registration

We will take care of your CA DMV registration for the vessel, which includes signing a Power of Attorney for the registration. We will email over a Power of Attorney to be signed and sent back. Once we have that, we mail out the temporary pink slip and stickers.
