CRT motor

[patchesII]

I know my best 2.5 never made 450 even on methanol. Was actually quite a ways from it

Hey guys like all the good comments . Like peanut man said, been a long time coming and a ton of R&D to get the girls to were they are today . Jerry Bird from New Orleans Street Outlaws will be making an anoucement on a new venue with some 450 plus HP outlaw outboard drag boats . This will host and call out the fastest outboards from our country and a broad. CRT is excited and will suport his effort.
Think the rules are run what u brung 1200lbs nitrous and 100 Lbs off if u don't spray . Think i herd TV guys and 2 days of his formate , big bucks for the top 3 . 1/8 th mile i think ,but not 100% on his call . So all the fast guys out there that want to play , keep your ears on , he's about to call .

Real racing has turns. Both left's and right. Bring those things here into some real water "salt" and rip em rally style through the back country.

Seriously I had this idea the first time I saw that street outlaws. It might be watchable again if they did a boat version. Love to see that happen. Good luck.

That's Special, I also heard they will be running in DSRA/ODBA this year?

The engines were approved to run in DSRA and ODBA in Pro Mod and Pro Drag at the same weight as the Mercury. Should give us a great comparison of the two different platforms

erik , does odba/dsra plan to let a 2.7 run at the same weight as the 2.5 merc?

[Speed Jr.]

Well yes, as Chris Alby told me they are actually 2.69 now. Dont shoot the messenger, this was what i was told.

A 2.7 will carry 50 more pounds than the 2.5 but that holds true for both engines. As long as they’re the same displacement they run at the same weight

Well with the weight at 1200# that will rule out the Ultra light current class Pro-Drag Outlaw boats

Good Point Rich. I would love to see the sub 1000 lb boats running these motors

[Da Bull]

No dog in this fight but if we`re talking about some sort of weight per cubic inch then it`s about time. I like that idea. No guessing just math.

[patchesII]

Weight per inch won’t work. It would heavily favor the 2.5. I’ll give an example, my boat raced pretty consistently at 915 lbs which gives you 6 lbs per cu inch. If you apply that to a V6 OMC at 218 cu in it would weigh 1308 lbs, a 265 cu in V8 would weigh 1590 lbs. The Mercury 2.5 would run away with it. The big inch engines would need to be under 5 lbs per inch

[tcrabtree]

Regarding weight , Someone explain to me why pro mod should be any different from the other spec classes ie lakeracer prostock 1400 mod etc? All these classes have a 2.5 weight penalty @ 5lbs per every cubic inch gained past standard bore.. 2.5 200 carries 100 more lbs than a 2.4 200 etc.. For example ,Ive added additional weight in LR for yrs just for using a .030 over bore so theres No reason a 2.6__ should run at the 2.5 weight. Most of these so called 2.6s are using Stroked cranks , 3.6 pistons

This is a Damn good point TC. I’m curious on this one.

I just got off the phone with Pro Marine and in less than 5 mins I got a price for the 2.5L 450HP power head. I'm not too keen on their terminology, but Julian said "short block"...whatever that means. So I priced out a CRT short block with my specs.

Well, then you didn’t get the price for a powerhead. A shortblock is not the same thing as a powerhead.

A shortblock is a complete rotating assembly in a block, but without the cylinder heads.

If you add cylinder heads (which is a bigger deal on a 4-stroke than on a 2-stroke), you get a longblock.

If you add intake, fuel system, and ignition system, you get a powerhead.

If you add adapter plate, mid section, lower unit, cowlings, and a bunch of smaller stuff like exhaust pipe and linkages, you get a complete outboard engine.
