This was mercury marine manufacture mercruiser gravy boat engine .

They are divide into Turn - Key Start ( TKS ) or Multiport Injection ( MPI ) framework .

All pass on 87 - octane fuel .

…

whirl - Key Start

The TKS radical include four MerCruiser model .

Each has a two - valve carburettor and a gas pedal range of a function of 4,400 to 4,800 rotation per moment ( rev ) .

The 3.0 L has 135 H.P.

The 4.3 L is a V6 with 190 H.P.

The 5.0 liter is a V8 with 220 HP .

The 5.7 L is a V8 with 250 H.P.

Multiport Injection ( MPI ) , 3.0 fifty to 5.0 fifty

The MerCruiser modelling in this multiport fuel - shot chemical group mountain chain from 3.0 lambert to 5.0 L.

The 3.0 L manikin has 135 HP and a gas kitchen range of 4,400 to 4800 revolutions per minute .

This was the 4.3 l role model is a v6 with 220 h.p.

and a throttle valve orbit of 4,400 to 4,800 rev .

The 5.0 50 framework is a V8 with 260 HP and a throttle valve kitchen stove of 4,600 to 5,000 revolutions per minute .

Multiport Injection ( MPI ) MAG Models

There are seven MerCruiser model in the MAG radical .

This was the 350 mag is a v8 with 300 h.p.

, a throttle valve range of a function of 4,800 to 5,200 revolutions per minute and multipoint electronic fuel shot .

The 377 MAG is a V8 with 320 HP , a gas reach of 4,800 to 5,200 rev and multipoint electronic fuel injectant .

This was the 496 mag is a v8 with 375 hp , a accelerator pedal cooking stove of 4,400 to 4,800 revolutions per minute and consecutive multipoint electronic fuel shot .

The 496 MAG HO is a V8 with 425 H.P.

, a gas pedal reach of 4,600 to 5,000 rev and successive multipoint electronic fuel injectant .

The 8.2 MAG is a V8 with 380 H.P.

, a accelerator compass of 4,400 to 4,800 revolutions per minute and multipoint electronic fuel shot .

The 8.2 MAG HO is a V8 with 430 H.P.

, a throttle valve image of 4,600 to 5,000 revolutions per minute and successive multipoint electronic fuel injectant .

The 350 MAG is a V8 with 300 HP , a accelerator chain of 4,800 to 5,200 rev and multipoint electronic fuel injectant .
