Probably you've never had a diesel engine.
Bad guess. We had a (one) diesel before, and we have two now.
No diesel odor.
Usually.

There is a myth that you can't get CO poisoning from diesel exhaust. Granted the amount of CO in diesel exhaust is less than from gasoline exhaust, there is still CO present. And it can still kill you (maybe just not as fast).

One of the strangest vessels I saw last year was a pretty large sailboat, with no mast or rigging. It had a 70hp or so outboard mounted on a bracket/swim platform. It was cruising at a pretty good clip. The captain looked to be 7 ft tall, he was huge.
When they hit my wake (not a huge wake by any means) the boat went wonky, the big guy almost lost his footing, and the roll was incredible. I guess sailboats are meant to be pulled not pushed.
ss - Interesting couple of reviews. Thanks
That opens my eyes better to "potential" [however small it may be] of CO from diesel fuel as being a dangerous enough content to cause death.
Albeit, as second link eludes: For CO in dangerous amount from burned diesel would need to be exacerbated by very badly tuned engine and exhaust entering a considerably air tight location. Seems that engine running to mfg specs would create only very small amount of CO... not enough to be dangerous
Statement toward end of first link [regarding diesel trucks]: "Lastly, an extensive literature review produced no scientifically reported cases of fatal CO poisoning attributed to diesel fuel exhaust."
I thought the Nazis used submarine diesels to gas people as well as gassing vans before they switched to ZxyklonB? I’m pretty sure the science is documented on that...... The vans might have been gasoline but the sub motors were certainly diesel. And they killed 10’s of thousands with them.
Even with perfect combustion you can exhaust products that can kill you. While you are unlikely to drown from the water produced, you could succumb to the CO2 if it collects in the area you are in (e.g. berth compartment, engine room).
A CO2 concentration of 20% is likely to kill most people.
Even if you found those numbers, I'm not sure they would have much relevance, unless you also had the number of people exposed to gas fumes compared to diesel fumes.
If there were 100 times more gas fume deaths than diesel fume deaths, it sound like gas engines are so much worse....but if there are 100 times more gas engines than diesel engines....the risks might be the same.
That was breathing, not berating.

No question, this is a trend. Sea Ray is offering more and more, larger boats with outboards. MJM announced the 53z at the Palm Beach show with four Mercury’s. There were a LOT of boats showing off new outboard tech in Palm Beach.

A nice advantage of multiple outboards is joystick maneuvering. Forward, back, pivot, translate, station keeping, all in one little stick. Kind of interesting to watch multiple motors all doing their own thing while moving a boat.
Jumping in to earlier thoughts. Yanmar now makes 50 hp turbo diesel outboards. You wonder how a pair (or more) of these would do powering a trawler designed from the ground up to use them.

For those who are worried about losing swim platform space to outboards, Sea Ray has a covered outboard design. Again, the boat would need to be designed at the outset to take advantage of these two ideas.

Outboard mod on a 1969 Pearson. Nice paint job!
