How many engines is ideal?
I finally have the time to research this age old trawler question and add to the body of knowledge of this wonderful site!
Sold my twin Yanmar Mainship 34 a couple months ago.
Since there are already plenty of threads debating one versus two engines, thought I'd explore twin versus ZERO engines. So I went ahead and bought a Hobie kayak!
Will post fuel, consumption, range, rpms, and other data in a couple months!

How about going from one engine to three. We met this house boat owner at Columbus Lock on the TennTom southbound and cruised together to port St Joe, Florida one winter cruise. The outboard controls mounted on the bow and he could steer with all three. Planned to get rid of the old single out drive eventually because it wasn’t near as fuel efficient as the outboards.
Rafted up at Bobby’ Fish Camp, best and only catfish in that area of the waterway.

Whatever is working to move you through the water is enough.

Once flew with a crusty old USCG fixed wing pilot that told me when I asked about engines....." I wanna look right and see nothing but engines as far as I can see...then look left and see the same....."
Crossing an ocean I might feel the same, for the rest of boating it just depends....

One of the boats I have inspected: Over 60'. Started with twins, but after its first season, due to not getting the top speed expected, a third engine was added, ahead of and between the original pair. same size, so added 1/2 again the hp. I assume he was satisfied, as he still has the trio, 15 yrs on.

Those crazy 4-6 engine setups are cool until Maintenance is due. It’s ridiculous. 4 engine commercial aircraft are dinosaurs. Too costly per hour ( with long term maintenance) included. Great during the maintenance honeymoon and certainly look cool.

Somewhere there's a prop repair shop salivating about the possible money to be made fixing EIGHT props...

We had a boat with twin Volvo Duo Props in it. We hit a submerged log and took out all 4 props at once. That was my worst underwater damage ever.

One. That requires only a fraction of the maintenance.

From someone who has had a boat with a single and now a boat with twins, one is the ideal number

So, is an engine a motor, or is an electrical motor an engine?
Are we allowed to count thrusters, as electrical motors, in this survey?

From someone who had a boat with a single and now has one with twins, 2 is way better than one.
