Hello guys,

I am thinking about installing a back up engine on my sears 240 sundancer.

Anybody did that and have some tips or advices to share?

Thank you
 
Problem is that I live in new caledonia and we do not have that kind of options.

If DSC/Tow Boat are not options I'd suggest your next best bet (for safety) would be to invest in a dinghy with a reliable outboard. And plenty of rode on your 240 anchor. In a pinch you anchor the 240, dinghy to safety and figure out salvage of the 240 from land...
 
That could be an option however usually when you are in trouble, time can be a real issue hence I do not see myself putting the dinghy in the water and installing the engine on it especially if the weather is somehow bad with waves and gusts.
 
Even so, I agree with the dinghy idea.

I don't think a dedicated outboard engine for the sole purpose of being a spare makes much sense. Mounting it would be awkward, ugly, and damaging to the boat. You'd also have to store an external fuel tank, and if you didn't regularly use that outboard and keep the fuel fresh, it would likely fail when you were already desperate for propulsion. It would also imply to future owners that you didn't trust the primary systems. (at least, that would be my first thought)

I don't have statistics to back this up, but I'd bet that most towing situations are due to: lack of maintenance, lack of fuel, dead batteries and poor navigation.

If you put extra care into avoiding the common failures, that only leaves random, unforeseen mechanical failures to leave you stranded.

A dinghy and Torqeedo could be your way out of that...

Well Even if maintenance is done in the engine, shit can happen.
And usually they do when you do not need it.
It is pretty easy to be at 1 or 2 hours from the shore when you navigate in the South Pacific and New Caledonia. South Pacific Ocean is not that Pacific and weather reports are usually not that accurate.

i suppose this is the reason most of the single engine boat are equipped with a back up smaller engine even if it makes the boat uglier.

In the well next to me is an older Sedan Bridge (non SeaRay) with an outboard mounted on it. The guy uses it as a trolling motor when he fishes. Ugly as can be.

What year 240 DA do you have? What's the swim platform setup?
 
On the swim platform mount a bracket, backing plate and a 9.9hp ...get an external tank and a long hose to go thru the door and your good to go.
 
One of my biggest disappointment's is that these threads never seem to end with photo updates...

If I ever convert my 400 to triple 200hp outboard power you guys know full well that there will be one hell of a photo thread started :)

Remember this from a thread from a while ago?

Not that ugly ;)

Did you have a situation where you had to use it? Is it easy to steer from the platform? Is that a L shaft? 9.9hp?
