Quite a number of places that marinize the Mazda engines.

A Google search will get you there   

Here's one of those places in the link click on the catalog

The outfit in NY that did Jeff's engines is out of business it looks like

Big heavy boat, I figure they used a gear reduction transmission like a Hurth with a 2.03 to 1 reduction ratio and pretty normal sized props, but that's just me figurin' or maybe looking at one of Jeff's pictures earlier in the thread

A 13B turbo was one of the most exciting race car drives I’ve ever experienced. Not the wildest, but clearly memorable to this day and that was in 1986.

I have not looked at prop numbers, sizes, pitch, etc., but just from a visual perspective, the props on this 1983 look significantly bigger than the ones on the 1981.



Above are the props on the 1981 with the V6 engines.
Below are the props on this boat (1983 with the rotary engines).

There is a place in Kannapolis (a couple towns over from me in Mooresville) that works on these engines, and even has experience with marine rotary engines. I may swing this by there and see if they think anything is salvageable.

Not that this letter means anything at all about its condition now, but I thought this was a pretty cool piece of documentation that came with the boat.

Did the seller give you any indication of the engine(s) condition?

I would use a 50:1 or 40:1 premix to fire them off at a minimum.

No, there was no indication that anything works from the seller. If something does, I'll just be that much happier.

I think I'd have a hard time tossing out the cool factor of the wankels in favor of V6's. Very neat project Jeff!

Guess I'm the only naysayer,turn them into anchors. They must not have been that great or everyone would have had them in their product line up. Plus the fact that they were not in the boat to begin with. Having to rebuild 2 questionable power units plus refurbish the boat will get you upside down fast

Gary,
I don't think you are the only naysayer:

Yeah, I am kind of torn on this one.

I am going to run the boat by the shop in Kannapolis that rebuilds these engines and see what they think. They have some experience with these in marine applications. If the cost is going to be crazy with unknown results I may go back to something more normal.

One other thing to consider is that if I do end up swapping them out, I'd need new transmissions and props too. If I rebuild these, the gears and props should still work.

You're probably right on that. I am still not sure what I am going to do with this boat. I will probably keep it and restore it, but I may sell it as-is if someone wants it and would be willing to save it. I just don't want to see a rare twin-engine Fish Nautique end up in the landfill.

Don't give up on those trans's yet. Think about all the boats out there running reductions and big aggressive props.

All things considered. My preference would be a donor boat or two , with a couple of useable engines and running gear. Something close to oem or better. K.I.S.S.
Really like the wankel idea but seems unrealistic now

Good point Gary, it's easy for someone like me to say "go with the rotary's" when it's not my time and money on the line! Or maybe I could suggest Jeff put a couple of Ilmor's in there.

But ..... if you grab a pair of 6 cylinders, and let's say at a minimum you have to refresh the top end, and maybe carbs need rebuild, and on it goes ..... I'm not sure that if you have someone knowledgable look at these engines that they won't give you the straight scoop, like "we have to tear them both down, new apex seals, blah blah blah and our estimate is $6,500 for the pair", in which case you move on and look elsewhere. If instead they say "let's spin them and check compression, if the seals are good we can clean them up, make sure fuel and ignition are working well, and fire them up" then why not give it a shot?

I agree Dave but since Jeff is close by to someone who is in the know with them it would not hurt to ask. They might tell him don't try starting them without doing x,x and x and might know someone looking to buy unmolested complete units which would maybe help offset new power. Like Bruce I wonder as well why someone would put them in,most with those boats want mileage- it almost like Joe or Tim took up fishing......
