As WreckDr. says, when I looked into the rules for my bat boat, f- factory modified engine class was for all the NA Mercury Racing Blue Motors. ie modified by the factory to a standard spec. without blowers etc.

Exactly.
Years ago they had my Factory 1 boat with HP500 in a class with stock 502 Mag boats. The stock guys claimed an unfair advantage so the people that hosted the event came to me and asked about the "new" Factory classes and requirements for the class. I showed them the rule book for Factory-1, F2 and F3, and showed them the seals on the HP500 engines.
As a result, the Shootout organizers created Factory classes more aligned with (at that time) current APBA Pro series classes. They tried to keep up with ghanges with the class, (500carb to 500efi to 525, etc.).

Thanks Gordo, Then the boat should have been in a differant class such as modified. Something tells me the Fountain new that from the last years protest.

SVL could be a Good class ,!!!............... a great class ! !!!

90% of the teams over the years have only improved it,s designation .Those who hurt it are pretty much just sittin, any how .So theyre input is moot .

Hopefully 7 will do the Last couple on SBI,s Schedule .

Actually ,OPA has one comin up down here in the panhandle . Since it was a slow year some of those racers , Orange Beach would be a nice place to covet as well

Really tho , the last three good race sites are comin up !!!

Exactly! That should have been an immediate DQ. Period.

Not true.
The intent of this class was engines that are legal for specific sanctioned racing classes.
Refer back to Von Bongos' post. He has been a vital part of the Shootout for many years

Not the first time they got confused on what class to enter. Opps.
