koen, what about polyethylene for boats?

Studied up on the Evinrude MFE 55 and it sure seems like a diesel. It also seems like Evinrude is trying not to call it a diesel. They even refer to kerosene instead of diesel fuel. Thanks for the heads up. It may be just what I need.
Still wish I could figure out what boat you have. Maverick makes a plastic boat, but it does not appear to have the hull design yours does.

Roto mold B/Whaler
I think I've got the idea of how to get photos on here now. Wish me luck!
The photo shown is just one of the nine in the link below.

Does it have a fiberglass liner?
Or fiberglass stringers?
Or is it entirely roto molded polyethylene?
I want one exactly like it immeditately. Knock off or no knock off!
Actually, I think you better call Boston Whaler and ask them if someone stole a prototype experiment with HDPE. 🙂

Fiberglass stringers? Nope.
It's ALL roto mold polyethylene, with Expanded foam in the hull void. Screws and fittings are through-bolted where possible or screwed directly into the plastic. For use as a work/ pleasure fishing boat I went industrial (by design) and used galvanized, all except for the bow eye, not being able to find one with a long enough shank. Mountings to the hull are with SS lag bolts, only because the galvanized ones all have deposits of galvanizing compound plugging up the thread, so when they are screwed in a pilot hole, they simply clean it out, enlarging it to full size. The SS lag bolts grab nicely; 1/4" x 1 1/2" usually.
You say you "want one", I'll check around and see if I can find any of the others, uncompleted, that the owners might want to part with.

Let me know.
I'm in the market, so long as they're legal. And I would really like to know who did the roto molding.

Regarding accessories...
One think I like about these plastic boats is that the vast array of cheap injection molded objects like the Rubber Maid stuff someone mentioned might actually look at home on these boats. I know you'll shoot me for this, but I was actually imagining enclosing the center console in a couple of Rubber Maid Garage utility storage closets. It would be easy to fasten a couple of them together, into an HDPE cabin, fasten it to the floor, cut out some window openings, fasten some kevlar window panes onto the outsides of the window, openings, go over all the seams of the cabin and windows with a bead of silicon caulk and, voila, you've got a sport fisherman with a decent stand up cabin (certainly better than a Bimini and curtains) for about $300 total plus labor. And whenever the salt and UV decayed it badly, as it soon would, as Rubber Maid probably doesn't use marine grade plastic, just go get another couple utitlity closets from KMart and repeat (recycling the kevlar window panes of course).
I know, I know, this is a design web site and it might make everyone sea sick looking at it, but when it comes to fishing where I am (and I would suspect where you are), staying out of the rain is paramount function and, well, form in this case, must follow function. Now if I were willing to be separated from 80 or 80 large for a Grady White 24, well, then aesthetics might be better underwritten. But I am a lowly crabber and this would do quite well for my needs.

dcwilson. Still want one?
It took a while but I finally found one for sale.
If dcwilson is still interested, send me an Email at gsutfin@telus.net
The one I found is bare but only $500 Canadian. Nice blue colour. I haven't been in contact with the seller but have the link to the for sale ad.
They were made in Langley BC Canada by a Japanese company. They were made under the name Sea Lion. Company doesn't exist anymore and I can't find anything else out about them.
