This couldn’t happen with a petrol outboard

[oldharry]

I would never recommend dunking as a service operation! I fully did not expect ever to get my Johnsons going again, but it seemed woth a try, and was! The fact it ran better was clearly due to there having been some minor blockage or maladjustment to the carb, rectified on reassembly. I was amazed it was running so well years later. I fully expoected the accident to be lkife limiting for the engine! Seagulls were the neaest thing to an engtine buiult to be dunked, with plain bronze bearings etc!

Equally true of immersing a torqeedo beyond its IP67 1m for 30 minutes.

To true, but the presence of an IP rating at least gives some confidence that it was at least designed to be hung on a 1" piece of wood 4" above the water, and that the likelihood was that it would get wet at some point.

It's not an ROV, so IP67 seems suitably adequate.

I had no idea. AFAIC that makes a seagull less maintainable than a modern 2T engine and far less likely to last. (Although they *do* seem to last....)

Someone with some real knowledge will be along shortly to tell me why I'm wrong!

Here I am. If your petrol outboard fell off while running it would stop. Pull it back aboard gently with the still attached kill cord.

If the electric outboard fell off it would continue running, shredding the inflatable dinghy, then make a freedom run for the gap in the reef dragging you behind by the kill cord.

I understand it can be a problem as you get older... ;-)

With the Torqueedo I would again have swamped everything with WD, its brilliant at removing water and moisture.

The solvent properties of WD might have made it the last time you used the Torqueedo. They are designed to be waterproof so best just to wash off dry salt (although that isn’t strictly necessary) and use. Officially they are only warrantied at 1m depth but as they example shows they are better than that.

The only thing that baffled me was that it fell off the dinghy as Torqueedo’s have exactly the same way of attaching as any other outboard.

No it wouldn’t - the kill cord would come straight off it and it would stop.

That was why they needed so much oil, it helped seal the bearings. I dont know what grade of bronze they used but it was one of much harder 'mixes'

If it jumps off while running just let it go.... nothing worth salvaging!

I have a clear childhood memory of my father's reaction when his outboard 'jumped off' the tender and continued running for a few seconds hanging from a lanyard completely submerged. I can't say what he did afterwards to sort it out it did give years of subsequent service.

My 2T Mariner got a dunking before lockdown, hard dinghy overturned and tipped me out!
I didn't have the kill cord active, the ob ran upsidedown for about a minute or two then stopped. I got it to the boatyard mechanic who air pressure cleaned the cylinder and plug, drained the carb and replaced the fuel, tank ran the ob for 5 mins and I then used it to get to the boat and back. I cleaned the engine when I got home and it was left to stand during lockdown. When I first used it after lockdown it took a few extra pulls to get it started and it has since been ok.
I don't think that a four-stroke would have been so robust.
