I agree with Jake,and if we make another class will that hurt 750? cottage boats are welcome Jake was the only one brave enough! it was great ! the 750 parts are cheap they are not all scooped up like the 850 stuff..the Hydromotive# 44 i think did well..add another 20 pounds see how it works before switching engines?
my boat i think is heavy id love to weigh it i need to find a local digital scale..but maybe i am maxed out in performance for my weight now aswell and light ones will only get faster? however i feel there is more just by changing props

What about making the 49 run with a 20" mid and maybe adding some weight to handicap it? Maybe the 20" mid alone would be enough of a change in handling to even things up? If people don't have a motor with a nitro case, they likely don't have a short mid either. I think it would be harder to find a short shaft 49 with a large case in stock form than it would be a short shaft with a nitro case. Not only that, the 20" motors came with power trim stock. With a short shaft you would have to rig up a Yamarude or go through transom.

If another class was to be added for a 49, I think it would make more sense to add a stock 850 class where 850 is actually the cc limit and the motors are all stock with the exception of trim. This would allow someone to buy a short shaft stinger, freshen it up, and run it vs buying a short shaft stinger, then buying a 56ci powerhead or complete motor, doing the mods to it and then running it. If people want to have them inspected, it would be pretty simple to check most things by removing the head. Port heights, evidence of grinding, bore, stroke, and chamber depth of the heads could all be checked very quickly. Even better, to avoid the cost of a head gasket, when you put the engine together, have it inspected by the tech inspector, put the head on and have it sealed or tagged or whatever you call it so that if the head is pulled off again for any reason, you can tell. It would be pretty easy to do this at the beginning of the season to avoid having your head tore off at the race and if you don't have it sealed and win but don't want to have your head removed, then you choose to give up the points.

Our T-850 class as it is can't be considered stock since there was never a short shaft 56 made except for an SST-60 which is costly, hard to find, and isn't even allowed to run in the class anyway in stock form. I like being able to play with the engine and the class appeals to me. I would also be interested in a stock 850cc class where things were checked to be stock. Powerheads for the 49s are cheap and easy to find parts for.

I like what we have now, I'm just trying to say that if another class was to be added, I think some people in the group might find what I wrote above to be a little more appealing than a class for people with a 49 short shaft with a large case. Just my 2cents

Best idea yet!
T750 stays how it is.
T850 becomes pure 49 + yamaha 70.
Make a T1000X class for the 56rs!!

That's the solution...but it'll be T1150X...so we all don't have to run SST60s :).


I'm 100% in agreement with T750 being a 750cc class...if you want to go bigger just bump up to the 850 class. AND if you have a 60mph cottage boat that you want to come out and run (for no points) than have at it...BUT this should be an option for those who want to try the class not to give an already established racer a chance to run more laps. ANYONE not running for points should be treated as a rookie and have to start at the back so you're not messing with the guys running for points. That is also a potential solution for the TCAT guys running with the T's...so we're both not messing up each others lines.

I have always like the pure T750 motors. I don't think we should change the class. The other point is WINNING! To most of us that is important. Finishing 3 in the heat, but, first in class may be OK for the 24 hours of LeMans, but I would want to be first in the race. PERIOD!
We let other boats race with T750's provided that they do not dominate. Family style boats that run 50 to 53 mph appear to fit well. The top T750's still win and to me that is MOST important. The non T750's are there so those drivers get the opportunity to try racing to see if they like it or as in Craig's example to gain more experience. They are not there to race for T750 points.
At this point lets look at those 49's being part of T850. We have a good number of T850 boats. We can put these in the slower group heats. When we ran the T750 with the slower T850's it took several laps for the T850's to catch and pass them.
Kevin offered some good suggestions.
Let's see how many of these 49 OMC, 52 Mercury, 53 Yamahas we can get and go from there. See what people have that want to race.

60 cubic inches is roughly 985cc. So what would be larger anyway? T990 has a better ring to it? Just sayin :-P

Ah right! What's the story on that one? Why aren't you running it?
