66 MPH V12 Formula | Tiara 39 LS Terrace | 7 Boat Checks - 7/3/2026

66-MPH CRUISER Four 600-hp Mercury V12 Verados push 48,000 lbs to a tested 66.4 mph and hold her on plane at 18 mph. At the docks, the same setup maneuvers without a bow thruster: the engines mount 4 inches apart with only the lower units turning. Below, she sleeps four with 6'7" of headroom and galleys on both decks.
 

OPEN STERN Only the lower units on the twin 600-hp V12 Verados articulate, leaving a wide, unobstructed swim platform behind. The aft lounge rotates to face a fold-down port hull terrace. Forward, wrap-around seating and a teak table anchor the bow zone on a layout connected by a single-level deck.
 

JOYSTICK READY This North Palm Beach, FL-based 2025 MJM 35 runs on twin Mercury Verado V10 400hp outboards with joystick piloting and Skyhook. Her pilothouse features electrically controlled forward windows and a 360-degree view, backed by a Garmin GPSMAP 12-inch plotter, a gyro stabilizer, and a bow thruster.

CHECK THIS FIRST Before a surveyor touches the boat, there's a checklist worth running yourself. Milky oil on the dipstick, soft spots in the transom, osmotic blisters below the waterline, and a fuse box full of mismatched fuses are all findable without paying for a professional. This walks through each one.
 

DIY CHALLENGES Some projects look simple until you are the one holding the wrench. A solo wake tower install turns into hours of improvising, swapping parts on the fly, and fighting the boat's own hull to get everything square. The tower ends up rock solid, but the top section goes on facing backwards, logo and all.
