I found nothing on the top page of that Antique Outboard Club's website about a BEARCAT 85. It seemed to be a page soliciting people to pay to join an organization, not a source of information on a BEARCAT.
The BEARCAT 85-HP four-cycle outboard engine is mentioned in my
article about BEARCAT outboard engines. I just recently heard some more information about the BEARCAT engine project by FIsher-Pierce. I don't think you can find this information anywhere else:
As I have mentioned before on many occasions, it takes a lot more capital investment to get into production of an outboard engine than it does to get into boat building, and entry into the outboard engine business has always been a much harder path to success than making boats. That is why there are hundreds of boat builders in the USA and only two outboard engine makers. The BEARCAT 55-HP engine was not selling as well as hoped for, according to some sources I spoke with recently, and part of the problem was pressure from the other established outboard engine makers discouraging dealers from taking on the BEARCAT line. I don't have anyone on record saying this, but that is the recollection of some people in the business back in the Fisher-Pierce days of Boston Whaler. A great deal of money was spent trying to make the BEARCAT four-stroke-cycle outboard engine a success, and when sales did not materialize, there was a financial strain on Fisher-Pierce. One might speculate that there was some debt, and that may have played a role in the selling of Boston Whaler to CML. Again, so far just some speculation, but certainly interesting speculation.
One fan of the BEARCAT 55-HP engine used to have an old AOL homepage with some pictures. I don't know think that webpage is still around. I used to link to it in the article about Bearcat, but it turned into a dead line several years ago.
It is not very hard to find information about the BEARCAT. A search at GOOGLE turned up this page about the 85-HP engine:
