Hi all,

In case my main outboard motor decides to quit I would like to install a second outboard, this would be transom mounted sitting next to a transom mounted rudder.
Motor mount would preferable be on a sled to keep it close to the boat (pull start)
Obviously motor would be operated via a remote cable system, so far nothing particular...

I am told prop next to rudder would generate bad vibrations in the rudder/rudder mounts... Can anybody comment?
To counter this I guess It could be installed in such a way that, when lowered, the prop sits behind the rudder...
But then I would need to work out a way to pull start the motor as it would sit and it being far behind the boat would

Now since the prop is not sitting on front of the rudder to improve maneuverability I would like to interconnect the rudder to the outboard to steer the outboard...

Looking for experiences, hints, ideas etc...

Thanks,
Djeeke

An alternative you might consider is mounting it on a removable bracket on the side of the boat.

My boat has the outboard on the transom next to the rudder. Not noticed any vibrations in the tiller. I have a 4 HP outboard.

Same here, a friend did have vibration, but only when the prop hit the rudder! Built in a well to cure that...
One assumes the OP has his main OB in a well? Since this is a 'get you home' emergency fit, then the simplest bolt on bracket that allows you to lift it clear of the water and has room to start and control it in the water. I certainly would not bother with cable contols for it, or link the steering, just offset it enough to clear the rudder's normal angle of swing.

My boat was relatively small a C&C 24 with a short shaft 10 hp Honda 4stroke on a very standard outboard bracket to starboard of the transom mounted rudder. It worked just fine. No problem with steering. Outboard could be raised to be clear of water when sailing. Or when moored.
When under power running very slow steer with outboard. When running even slowly the rudder was able to steer just fine. No vibration problem I can recall.
Starting no problem raised motor pulled cord. Lower into water check cooling.

Not sure why you would want 2 outboards. My motor was a mid 80s and never gave me any problems. If it did I had sails.
The short shaft did mean a fat bugger like me going forward could be an issue. So I would recommend a long shaft sail drive. Yamaha make a nice one. Get it serviced annually, keep your fuel fresh, and you won’t need a second one. Carry a simple tool kit. Spare plugs, carb cleaner, JIK.
I did once have a slightly disconcerting problem on a C&C 24 with an outboard on a bracket. Also a short shaft.
Coming out of false creek with a good sea breeze. Some AHole in a big power boat blew past really close and his wake put my motor under and killed it.
Hauled a sail up PDQ in a narrow channel with a lee shore and an inbound tug and tow. Made for some excitement. But all ended well. Once clear pulled the motor up took the plugs out and checked for any water. Dried it off and started it after a couple of pulls. It was a seagul. Not sure if a Honda is quite as robust.

I found the outboard was a very clean space saving option on a small boat. Fuel was relatively easy to get anywhere. If any servicing was required just lift it off and take it with you.

I always run with two outboards. The main outboard is on a transom mount next to the rudder. never noticed any vibration problem. Second outboard is in the Leisure 18 designated outboard well (main outboard is too big to fit in it! - outboard being part of the package when I bought the boat).

A good reason to have two outboards can be that the second outboard is from the tender and you may as well have the ability to use it if the main one fails assuming that you don't leave it on the tender at a swinging mooring .

The engine on my 9m Catalac is an outboard and I don't see why it should be any more unreliable than single inboard. I do have a dinghy and outboard and after many years have never had to use it in an emergency - yet.
