one prop instead of 2

At the time the post was created, there was a question from my side. Thanks for all who shared their opinions.
The others waste their own time as long as they ask THEIR questions that outside of the scope of the subject)).

 

Yuri - a few gentle jibes aside, we are all here to help as best we can - don't take offense at anyone's comments, they're (usually) made in good faith.
Apex is almost certainly spot on in regards to moving the engine room. The cost of doing so would exceed the cost of installing 2 smaller engines.
And I was only 1/2 joking when I said rip the pair of them out. For the amount of travelling you're talking about, you could get towed. It's simply not worth the expense of making major changes to the vessel unless you're going to get some kind of return from doing so - be that financial, pleasure, or whatever...

Now, back again to my original question.... why?
I think you've answered that to some extent - you want to free up the space currently occupied by two oversized engines. But what else are you trying to achieve? Do you intend to do a complete makeover of the vessel, for instance. And what do you want it to be capable of when you are frinished?
These are fundamental questions - there's always more than one way to skin a cat - give us your desired outcome and maybe we can help to provide the best means of achieving it

 

Hi Will,
sorry if it sounded offeensive, was not supposed to be.
On this ship, it is easier to use another compartment for engine room, because existing one is full of pipes, cables,pumps and whatewer else stainless steel and aluminum staff that takes long time to remove. And it is really huge. Yes i do complete makeover of the vessel.
When it comes to financial side, let me do the calculations myself, as i'm better informed on the local costs.
Towing the vessel trough the river to the lake with all its briges and dams by the way -that is expensive.

 

You might consider a thrust bearing at the end of the first from the propeller shaft. That will allow you to use any engine and connect it with a truck style drive shaft,locating the replacement engine mostly in line with the old.

IF the existing transmission ratio is correct , you might mount it where it is and drive the trans with a simple truck shafting .

Should parts and cost be a concern.

I did the same Yuri, I removed 1000hp engines, put in two 250hp, and now I have big bathroom and extra engine room. I am still looking for thrust bearings. Fast Fred any ideas on thrust block for 2 -1/2" shafts used or something. Aquadrive and Python, too expensive.

That's because there MARINE.

Go to an industrial bearing supplier and see what he has for your 2 1/2 shaft.

Should be 1/10 or 1/20th the price of "marine".
