The problem is mine seems really hard to access, which makes it impossible to change when you're at sea. I'm trying to figure out changing the empller.
Thank you

The water pump is on the front of the engine (cabin end), as in the video, correct?

If you have any other photos that might help see what's going on.

It might be that your hoses need to be rerouted so as to provide better access.

The probelem is there are two empellers the one on the front og the engine I've changed the one on the back is really hard to get too.

Ah. That's the original fuel filter, I think, on the side of the engine. My impression is they are frequently replaced with with a Racor unit mounted for better convenience, because old boats have crud in the fuel tank and filter changes become periodic preventative maintenance.

Some of us here have the 5411 and will know more.

I wonder if he's talking about the heat exchanger, which has plates on both ends, but it's not a pump and doesn't have an impeller. Heat exchangers do need to be serviced regularly, and are hard to remove cause the hoses never come off easily.

You have 2 sea/raw water pumps ? I am not familiar with this engine but I have a 5416 which is similar, I thought anyway. In picture one is that the pump on the front of the engine your trying to service ? What is blocking access ?

 

[Loren Beach]

Can you follow the hose from the seacock to the raw water pump on the engine, and then to the heat exchanger?

That might be a good start.

The yellow is the impeller location and the blue are the 6 screw heads, and the red is the working space. This impeller is on the opposite end of a continuous shaft from the front of the engine which houses the raw water impeller. and on the

Stephene, Can you back up a little and take a picture of the front of the engine ? Pretty sure the seawater pump is on the front of a 5411.

 

[Dave G.]

5411 picture, I believe the pump is lower left ? Does this look like yours ?

 

[Christian Williams]

According to this guy, it's the fuel pump.

 

[Dave G.]

Fuel pump ? I would think the fuel pump is up above that where the injector lines are connected ? The hose size looks a little big for fuel too, don't you think ? After watching that video it looks like the fuel pump is on the starboard side of the engine.

 

[Christian Williams]

Looks to me that "fuel pump" location is compatible with what the original poster shows--starboard side of engine block, under the throttle linkage. Yeah, the hoses are big on that model. Confusing.

This video is very useful for owners of the 5411, but I wish the guy had paid more attention to lighting and a steady camera. It's not that hard to do.
