"C" mod????

[Sonny]

Is there a pro class a good "C" mod can run in?? How fast is the "RB" class??

[sam]

Not really. PRO allows deflectors to move down one class ... that was started many many years ago, but hasn't been practical in quite a while. RB kilo is 90, CMH kilo is 83. The 5 mile 4 lap records are 67 for CMH and 78 for RBH. RB doesn't run anywhere geographically close to you anyway.

A more up to date scheme would allow the old deflector motors to move 2 classes.

[Sonny]

ok

does this mean I can run my alky deflector 44 merc in "RB"???

[sam]

RB is a B class .... restricted B.

PRO rule A, #2 ... 44 deflector is eligible to step down to 500cc, yeah, right

[David_L6]

Brian Payne ran his 102 mod (Yamato 102: stock powerhead with open megaphone exhaust, any lower unit) in RB at the PRO Nationals a few years ago and placed very well.

On a long course a 44 Merc deflector may be able to keep some 250's in site. 350's would probably lap it.

PRO rules ??

I am not sure how one interprets the PRO rules so far as deflector motors
go, but they must not be thinking of the 44" Merc , as a legal stock mod motor. I assume they mean an 'alky' version of this motor, one running on fuel, high CR, any carbs[overflow Carters, or Mikunis, or ???] 3rd ports , 6" pipe tower, any good lower unit, modern four /five blade props etc.
IMHO, a 44-alky would run away from the 250s and RBs, and may run up with the 350s. One might even get a pipe to work on this motor. But why bother when there are good race motors available. But it would be fun to dig out a mid 60s C Merc alky,
if only for the sound and smell.

I don't have an overwellming urge to run an old school alky 44. I do have this brand new 102 mod that's ready to rip it up, and I doesn't make a lot of sense to me that there is no pro class to run it in. I mean really, I started out with a whole garage full of merc stuff. I spent thousands of dollars for the right boat and the right motor and now the only thing I can race profesionally are the merc's I started out with. I could understand if there was no osy 400. OK forget the mercs. I can race osy 400, but it I modify the motor to go faster I cant run it?? that's not fair. the army is supposed to be more hardcore than the boyscouts, pro racing is supposed to be more hardcore than racing for sport, and modified outboards are supposed to be more hardcore than stock outboards. so what gives??? If anything osy 400 should be a modified class slamming the door on the slower boats, not a stock class slamming the door on the mods.

[sam]

But a 44 is not a legal 350, it is a legal 500

That's why I say they should change the step down rule to agree with today's reality .... step down 2 classes (3 for the 722cc 44ci Merc)

[sam]

OSY400 is a UIM class that was absorbed into APBA PRO .... not grown from APBA PRO rules.

This was done because APBA PRO is closest to UIM "O" classes

[Sonny]

So let me ask you guy's this. If enough "C" mod guy's were interested could a pro class be formed?? maybe a 400 mod class?? Ive been watching the roll call's for these races and there seems to be a growing number of modified Yamato 102's and 302's.

[sam]

Anything is "possible" but some things are less likely. Maybe C-Mod Yamato guys like C-Mod ....


Most Stock and Mod racers view PRO as a separate sport; I doubt you'd grow much interest in a alky 400cc class .... there are already 350 and 500 classes without motor maker restrictions, a basic idea in current PRO thinking

[sam]

Adding a new class isn't the most popular thing these days .... the USTS doesn't even use all of PRO's current classes

400pro ?

Sonny; -you can run your 102mod as a PRO, but you would be embarassingly slow, 1]because the 102 is 400cc, and would have to run as a 500,
2]it has been true now for 80yrs. that a modified stock motor will never keep up with a made for racing motor. The best chance you would have is to sleeve the 102 down to 350cc and run as a 350PRO, but even on fuel, it would be slow compared to what they run today.
Other than the Nationals, most clubs would let you run in 350, maybe with the 250s, if you comply with the rules. Convert the 102 to fuel, raise the CR a bit, and go have fun with the PROs.

[Sonny]

That's my whole point, osy 400 isn't an alky class but it is a pro class. Now take that same osy motor and put a stinger pipe on it and it's no good??? what pro class doesn't use a stingerpipe?? Truth be known, you cant really do to much within the rules to a Yamato powerhead for mod, the biggest thing is an alky style pipe.

Sonny, more can be done to a Yamato in mod than you think. But, if you want a Cmod motor that has more options for mod, then get a C Merc..........
