RTA it is just the model number

as to exhaust mixing with air that is no problem as we supply more air to the engine than it needs so some air is caried over to the exhaust manifold since there is no fuel in the ait it is no problem

the engine has a mininum running speed of about 25rpm

The bearings are plain bearing but we use shells just like you do in a car just they are a wee bit bigger

As to getting a dead engine out it would have to be very dead before we evn thought about what is basically done is take the ship into drydock and cut a hole in the side or take the top off and lift it out.

But it is amasing what can be done in place to grind a crank you get a machine that clamps onto it and spins itself round the crank to grind it in place.

As to throwing a rod it would be pretty horrendious but thank fully it don't happen often the bearings tend to wipe out first.
