Top­notch tech­nol­ogy in new Honda out­board

NT News - Motoring - - MARINE GUIDE - By JON HUIE

IT has been a long wait for loyal Honda fans but the com­pany’s new 250hp fourstroke out­board will be avail­able soon.

Pre­vi­ously, the highly ac­claimed 225hp model was the largest in the range, which re­stricted Honda from pow­er­ing up elite-brand 6.5-7m blue-water fi­bre­glass boats like Cruise­craft, Haines Hunter, Whit­t­ley, Sig­na­ture and North­bank.

Cu­ri­ously, the new V6 sin­gle over­head cam 3.58-litre mo­tor has a smaller dis­place­ment than com­pa­ra­ble Yamaha and Suzuki four-strokes, and yet it is about 14-23kg heav­ier. But the BF250 gets all of Honda’s renowned top­notch tech­nol­ogy, in­clud­ing multi-port mi­cro­com­puter pro­grammed fuel in­jec­tion, VTEC vari­able valve lift, BLAST (Boosted Low Speed Torque) and the com­pany’s patented ECOMO lean-burn fuel sys­tem.

In an out­board in­dus­try first, Honda has in­tro­duced a di­rect-air dual-cir­cuit in­duc­tion sys­tem. One cir­cuit draws cool­ing air into the front and around vi­tal en­gine com­po­nents. It is sup­ple­mented by a top-mounted al­ter­na­tor cool­ing fan.

The sec­ond cir­cuit routes air from up­per cowl­ing in­take vents, re­moves mois­ture and then in­ducts it into the throt­tle body. Honda says the cooler denser air re­sults in bet­ter com­bus­tion.

A new idle-charg­ing sys­tem caters for hi-tech marine elec­tronic suites. If the en­gine man­age­ment unit senses ex­ces­sive de­mand, there is an au­to­matic 100rpm in­crease and the al­ter­na­tor gen­er­ates an ex­tra nine amps.

The BF250’S slim 60 pro­file al­lows for mount­ing du­al­counter ro­tat­ing en­gines to larger craft and a 2.00:1 gear ra­tio pro­vides a wider prop se­lec­tion for tweak­ing out­fits to pro­duce the op­ti­mumper­for­mance.

Avail­able through au­tho­rised Honda out­board deal­ers.
