Chinese diesel auxiliary?

No. Not picking a fight. Just an observation . i am certainly no expert but i can tell you from experience that getting a complete marine engine will save a lot of headaches. Good luck with it whichever way you decide to go.

 

Fwiw if my boat wasn't a double ender it would have an outboard hanging off the transom. There's a lot to be said for outboards especially with the 4 stroke high thrust motors available now.

You should be able to replace the Atomic 4 with a new Honda industrial engine in the 20 hp range. B&S make a 25hp or so V twin and Wisconson also has offerings .

The Atomic 4 was never very strong and almost never cruised at full tilt , so a modern gas industrial engine will be quieter , faster , have better fuel burn and be far far cheaper.

Parts will be available for decades , not unobtanium in days with a Chinese something.

IF there is no self steering unit hung aft ,,a lifting bracket can be fitted for an outboard.

 

I like the industrial engine idea fred. How would you set it up. Ducting for airflow and water cooled exhaust .

 

FWIW the Suzuki 1 litre/ 3 cylinder engines as found in Chev Sprints were very durable and tough engines,usually last 200k miles with care. Bet you could pick them up for a couple hundred dollars.

Or going to diesel,there's many,many VW diesels around.

 

I've often wondered what would be involved to fit one of those suzuki s on an outboard leg. They are great little engines.

 

I had a turbo Sprint that I flogged mercilessly for 3 years and 120k km,never let me down,never burnt any oil.

I'd imagine:
-move oil pickup to bottom of the sump,or dry sump and use 2 electric driven pumps. It may be at the rear of the engine anyways and only need an adaptor?
-fitting an oil rail to spray an oil mist to the cylinders. Adapt one from a turbo engine from any turbo car.
-do the same for the cam
-need to drain oil from the head,an external line?
-it's injected so it should run.
-likely need to reverse the cooling so it runs from bottom to top.
-etc

 

Keep in mind that your repower may require that emission standards be met depending where you are in the world .
