Engine
4.3 liter gasoline en gine in a V-6 con fi g u- ra tion fea tur ing: seawater cooling with cast iron cy lin der boat block, cylinder heads and ex haust man i folds, which are specially de vel oped for the marine en vi ron ment. The exhaust manifolds and ris ers are EDP treated for in creased du ra bil i ty. The 4.3 also features a balance shaft lo cat ed in the center of the en gine. The de-sign of fers quiet, virtually vi bra tion-free op- er a tion by coun ter ing the pri ma ry im bal ance of a stand ard V-6 cy lin der confi guration. The advanced combustion system min i miz es noxious exhaust emissions and enhances overall enjoyment of boat ing. In addition, the seawater pump is lo-cated on the front of the engine for easy accessibility. EVC/MC – Plug and go (option on GXi)
EVC Electronic Vessel Control is the latest development in instrumentation for marine engines. It offers a higher level of integration with your boat: speed, tank level, depth and surface water temp as well as an optional trip computer integrated into a uniform in- strumentation. EVC makes boating easier offering new software options such as power trim as- sistant, a function that adjusts the power trim depending on engine rpm. EVC is scalable from a classic dashboard up to advanced driver information systems. The system is built on the latest automotive technology with waterproof connectors, so it’s just plug and go. Electrical system Fuel injection (GXi)
The electrical system features a 12 V corrosion-protected marine elec tri cal sys-tem which meets the U.S. Coast Guard requirements. The en gine is wired for easy plug-in con nec tion to the in stru ment panel. The engine elec tri cal system and the elec tric hy drau lic power trim is pro tect ed by a 40 A circuit breaker and comes equipped with a 75 A al ter na tor. Full in stru men ta tion in clud ing trim gauge and wiring har ness (op tion on cer tain markets). The Multi Port Fuel Injection system is mon i tored by an Elet ro n ic Control Mod ule (ECM) and gives the fol low ing ad van -tag es: more responsive and smooth er ac cel er a tion, excellent turn key starts in all weath er conditions, smooth reliable idling, reduced fuel consumption, and improved control of emis sions. Additional features built into the sys tem include: engine knock control for com pen -sa tion of less than perfect gaso line, over-speed protection, rpm re duc tion of the en-gine for low oil pres sure, high engine tem- pera ture, and low voltage, platinum tipped spark plugs for longer life and trouble-free starts, al ti tude com pen sa tion for air den-sity, and self-diagnostic capabilities. Also, there are two fuel pumps for low and high pres sure respectively. Aquamatic sterndrive
The Duoprop drive with its twin coun ter-ro-tating propellers features ex haust outlets through the propeller hub and cav i ta tion plate producing a har mo ni ous drive unit with un beat a ble char ac ter is tics in the boat in terms of speed, ac cel er a tion, steer- ing, ma neu ver ing, fuel econo my and less noise and vi bra tion. The drive is equipped with a cone clutch for easy and smooth shifting, pat-tern-matched spiral bevel gears for op- ti mum strength and minimum gear whine, a break-away shaft cou pling to prevent costly drive train re pairs, and sacrifi cial zincs located both on the drive and tran- som shield. The drive is equipped with easily maneu vered hydraulic power trim for ob- tain ing the best running position at differ-ent sea and load conditions. A choice of stainless steel and alu- mi num propellers are available for dif- fer ent ap pli ca tions. The 4.3 features standard pow er steer- ing for maximum driving com fort.
