The Yanmar Diesel Outboard has been out of production for a long time, and is extremely rare. Best wishes.

Does anyone know what ever happened to the Evinrude "Vindicator" (Bombardier), a 55HP, two-cylinder, two-stroke, direct injected outboard ?
This outboard was promised to run on Diesel (1 and 2), JP4,5 and 8, home heating oil #1, kerosene, gasoline, ethanol, and bio-diesel.

I've been curious myself, Gord. Here's a couple tidbits:

New Evinrude outboard runs on jet fuel, comes in "stealth black"

Evinrude's Multi Fuel outboards

The engine is designed for large ribs, with a 20" transom height and a rope start. I suspect its based on the ETEC 50, so there might be remote controls and a starter for it, but I doubt there's a longshaft or extension. Evenrude's site mentions a high thrust prop, but doesn't include data, so I suspect it isn't going to be an out-of-the-box solution for catamarans. While it has a switch to select different fuels, including gasoline, the write-up only mentions the lower viscosity kerosenes, not fuel dock or over-the-road goopy diesels. It seems to be a very pricey solution to a very rare problem; NTSB, CTSB, MIB and USCG accident records don't support the traditional fears* of gasoline on board.

* I've left out my personal opinion on this subject.

Come on, Sandy, you're amongst friends. You don't need to soften that down so much it's nearly out . Besides, I heard you have some insider information on NTSB. Like, you know an ex-investigator or yourself.

I see him every afternoon*. He's an opinionated, self righteous, pompous couch potato who needs internet forums the way a dog needs a fire hydrant, he checks back every day to see if his scent is still the strongest!

In my recollection there just wasn't a large demand for this type of engine and you are very limited as far as choice. As Talbot noted Yanmar was the only manufacturer that manufactured a diesel outboard that would fit the Catalac 8M or 9M.

These may be difficult to locate.

Other than your repower project, how's the boat coming along? Have you had the opportunity to sail her?

Syoung
have you ever tryed to buy petrol on the East Coast? i could not find petrol for sale in any of the Marinas i looked,i was almost caught out at Orford ness,i got lucky as a little old lady in her hardy had a spare can thar she sold me.
At Lowestoft i had to call my son to come to the marina and pick me up
At Levington the petrol pump does not work anymore

and the best laugh was after i filled up two 25 liter tanks at Ipswich,the assistant told me that it was "Illegal" to fill up two tanks and that i should have only filled one???????? anti terrorist legislation

The price difference is that i spent 120.00 on gas motoring some 90nm from North Norfolk down to the Deben,using a diesel would have cost me a tenner

Yes thanks Rick, we had some great adventures during spring and summer 2008, weather was a bit hit and miss, but we ventured up as far as Woodbridge on the River Deben, Ipswich, Harwich, Pin Mill and the Walton Backwaters. We'd planned a trip to Holland but it was blowing 35 knots in the North Sea, so we abandoned that idea.

I've always been careful to have a few cans of petrol on board, as the wind always seems to be on the nose when we head back to Tollesbury... luckily not had to find petrol during any of our trips.... I guess thats another reason for wanting a diesel - having to carry cans of petrol on board...
