OMC 25 motor approved for A mod

[DrRick34-0]

I saw where the omc 25 closed up passed for the A mod class. Where do you get the rules for the 1974 motor? what downhousing and unit is legal? Need help!! Would like to try one in this class.

Rick,

The OMC 25 and the 25SS Mercury in stock format will be legal for A Mod classes in 2005. I have a set of sheets from 1974; however, the MORC Tech Committee must evolve drawings and usable specifications.

I didn't race in 1974 however I'm told the OMC ran on a tall Merc drive housing and gearcase. I'll post more when I learn more.

Jeff, I do have my old SO rules from 74. Give me a fax # and I'll send it to you.

I don't really know what the leaders had in mind, but the 1974 rules with regard to the OMC and Merc powerheads allowed use of either the Merc or OMC mounted on either the Merc or Hot Rod A/B tower and foot. Cowls could be removed but as I read and remember the rewind must be retained. The flywheel ring gear could be cut offbe used. The OMC powerhead could specifically NOT be used on the 'new' 25SS tower and foot. Min weight on the OMC flywheel is 3lb 13oz.

I assume we are allowed to run a MOD exhaust. But in keeping with the other rule on 'new' engines I assume is must be a 'quiet' pipe and not the 25Mod megaphone. Otherwise they ought to just allow them on the 20H conversion. I know that right now no one has a working expansion chamber for the OMC, I am trying to create one myself.

Mike the 25SS class Mercs and OMC ran with closed exhaust in 1974 and even after that so I dont believe that they will be allowed to run with any type of open pipe. APBA will have to clarify that part of the rule.

[Mike 41P]

Yes, closed exhaust in SO. But they are added to A MOD!

It would be a joke to put them in A MOD with stock exhaust.

I was running BSH and 25SSH in 74. My 20H was always faster than any 25SS. And I have run that same 20H in A MOD and I don't really have a chance against a healthy Amod Hot Rod

25 OMC as an AMOD engine

Mike 41P,
Please send me a copy of the 1974, OMC 25 Specs. MY fax # is, 573-581-7788.
Do you recall if the stock OMC 25 flywheel was used, or the cut down version allowed in the 25 Mod class?
Can`t see why a stock rewind is needed. We want to get boats on the water not have them stalled in the pits with a broken rope or recoil spring, these are a 30+ year old item.
In my opinion, if this 25 OMC entry works out the population the A Mod class will increase. Thanks.

Mike, how about faxing me a copy of the 1974 OMC 25 specs, 912-354-1607
Thanks Bob

I guess I am still a little stumped. Why are we allowing all of these 20 and 25 cubic inch motors into the a mod class?

These are b motors. What is the goal? It would actually make more sense to make all of the B Stock hot rods Amods and make all of the 25 OMC, 25 ss, and 20H's the B stock class.

How many new drivers are we going to gain by adding these motors to the A mod class?

Anyone ?

Scott,

I have to agree with you on this. Endlessly adding motors to a class is no the solution. I shrug it off as being a mod situation, and solution. Which does make it very different from stock. But who, honestly, is going to get together a 25ss or OMC 25 to run in A mod? A small handful of guys, more than likely will get the rigs together and be no more than stragglers in the field. Like Mike said, the 20H is faster than the 25ss. Hell, in 1980, when my dad won the nats. in CSH, his BSH rig was just as fast as his CSH rig. These motors just arent realistic solutions for this class. Do we really want to increase the number of participants, if it doesnt also increase the level of competition?

[Brian10s]

Scott & Ryan,

Everytime this comes up, I fail to understand what the issues are that bugs everyone. Contrary to what most think, there are guys out there who want to tinker and also want to put their old engines back on the water. Is it supposed to be bang, out front? No, it's not. But not every driver needs to be out front, banging sponsons with the lead dogs. Some (and I know this is hard to believe) just what to go play with their boats and go for a ride. What about giving them the oppurtunity, twists your shorts? It really doesn't hurt anything.
All it is doing is providing an oppurtunity for guy to get on the water with cheap, available equipment. Not new but cheap. If it increases the class total by 1, it is worth the effort. Does it matter if it is a new driver or a guys 2nd class? Would either of your clubs turn down the extra $20 (or whatever entry fee is) because you don't agree with the drivers engine of choice?

And if not a single person does this, what is the harm? If it doesn't go out and dominate the class, who does it really hurt?

As for this being a Mod situation, well maybe your right. Is that because Mod would work to find a place for these engines and drivers to get on the water and Stock would not? Is it really that bad that 1 motor can be used in more than 1 class?

Which is more important, participation or competition? Or are you only saying that you can't have competition without 12 boats within 2 mph of each other? And, if that is true, are you willing to tell those drivers who don't want to go deck to deck that they aren't "true" racers, because they can't/ won't compete at the same level as Outfront Joe? Or that your club will not accept their entry fee unless they can prove they increase competition? Or maybe increase the entry fee for Sunday for those that don't finish in the top 3 on Sat?

OMC 25 as an A Mod

Isn`t the OMC as a legal A Mod engine a done deal? Hasn`t this ballot item already passed? Thanks.

[Jakeroub]

I like this new rule. Mostly because I am currently a college student building a 25ss just to screw around with for now. This rule will make it a whole hell of a lot easier for me to get into my first race. Who can say that is bad? I'm sure that after a couple of races of me getting left in everyone else's roostertails 'll have to get a real motor.

[ryan_4z]

Just a thought, but wouldn't anyone who wanted to get tohether a 25ss stock motor, and race uncompetitively, have already done so in the 25ssH Stock outboard class. In case some of you didnt know, the 25ss motor is legal in 25ssH. Anyone interested in just a 'ride', with no intentions of winning, can already do this with this motor. Why is this situation different from A mod?

[reed28n]

Brian,
I don't have a major problem. But here are a couple of points I would like you to consider.

Local clubs can race anythignthey want, without the need for a National class.

We have many regional classes now that I think under the old rules of APBA would been on probation BSR, BSH, DSR, 45SS AMR
DMR

By continuing to keep old equipment alive especially in the Stock category, when we have a place to run it inMod, we prevent ourselves from planning for the future and future motors. The perameters set by the old Stock motors that we have Modified over the years to raise the speed by 10 MPH set the bar too high for a real stock motor to be introduced in the existing class.

I am all for the guy that doesn't want to run out front because he makes it possible for me to race period, and I am also a guy who takes advantage of the rules to race an extra class now and then.

I want every one to race, we just need a congruant plan that flows from Stock to Mod, that won't tax the inspectors and won't stretch the race day. By keeping so many classes we make the local clubs reponsible for eliminating classes from the shcedule. Those calls should be made by the commission to keep the number of classes reasonable and find a place for equipment to run until it has to be phased out.

Final point. We should be introducing new motors. Not 1970's motors.
