REPOWER

We are pleased to offer you the most aggressive pricing in the industry on all Mercury outboard motors. Tiller handle models 25HP and below can be shipped to your door or place of business for lower than you think due to large volume rates with our shippers. Call today to purchase your new Mercury outboard and we will ship it out the same day! Call 954-926-5250 to order portable Mercury outboards.

Larger Mercury Outboards (over 25HP) must be installed by at our facility by one of our certified Mercury technicians. We offer free pick-up and delivery for all of our customers in the South Florida region, and we offer competitive pricing on installation. Call 954-926-5250 to order large Mercury outboards.

 

Nautical Ventures is your official Mercury outboard motor engines headquarters for South Florida. We’ve been helping boaters in Miami, Fort Lauderdale, Dania Beach and Palm Beach stay on the water with trouble-free enjoyment for over 30 years.

 

Easy to Gauge.

Accurate digital information is presented in a clean, easy-to-read gauge for instant, reliable information at a glance. Combined with additional sensors, Mercury’s standard gauges are powerful tools to provide safety and comfort while on the water.

 

Corrosion Resistance.

Mercury’s proprietary formula – XK360, is an extremely low copper content aluminium alloy, which leads the industry in corrosion resistance. This makes costly corrosion failures and high labour bills a thing of the past. Most competitors use alloys with 2% to 4% copper content which will corrode faster than our MercAlloy, XK360 or A356 alloys

 

Repower with SeaPro.

The compact size also means older boats that were not initially designed for the weight of heavier four-strokes can now be repowered and reborn to perform at their best with the latest technology.

 

Stiffer Upper Mounts.

On the SeaPro range the upper mounts are designed to be also two times stiffer than recreational models to maximize durability. Their longevity makes them ideally suited to the demands and rigors of commercial applications.

 

High Displacement.

Higher displacement equals more torque. The SeaPro 150hp FourStroke has plenty of it, which lets it churn out power without raising a sweat. Greater horsepower and lower weight equals better acceleration – that means better handling and control.
