[shawn911]

[scc82]

did not make a 200 bp and no bp in 93

[shawn911]

i might be off on the year,will check serial number tommorow.sorry ,what should a 200 bridgeport do on the 20ft vt rocket

Saw one a few years back with a '94 build date.........

Look for tha date stamped in tha block half at tha base of number 2 clyinder. Right serial number should be stamped in tha flange where tha block halves meet. Clamp bracket numbers may/may not be good...........t

A 200 is a black-painted block consumer bass fishin' 200 with oval exhaust ports, 2.4L or 2.5L.

2.4 Bridgeports were typically 225 hp (carb) and 240/245 hp (efi) race motors wityh bare aluminum blocks, made from the mid-80's thru '91(?) or until the 2.5's came along.

My boat, although not a Stratos, ran 80 with a 200, and 95 with a stock 240 hp Bridgeport, so there's a big difference.

Sounds like you're on the right track with the Bob's foot work.

[DerStream]

yeah that sounds rather late for a bridgeport, if EFI 245hp, some Carb were 225-240 hp depending on 7 pedal & 5 pedal because there were 5 pedal bridgeport carb also.

That stratos should be a 85 mph boat and thats being conservative.

There is a 200 oval port thats unpainted also Pyro. Tha BP and tha oval port carb motors had 5 petal fronts. Only seven petal carb (HP, not production) front from back then was a 2.0 Champ motor rated somewhere around 290 hp. It was pretty much a "got ta get it off tha truck" motor. Was REAL hard ta buy for a walk in customer............t

[pyro]

I left out a few of the models, (Mod-VP, SST120, etc.) that's why I said "typically." ;)

[shawn911]

tahnks guys its a carb motor for sure,i will post the year and serial when i get off work,ill see if the guy selling has any pics to post.

[Carter Powell]

I had a late 80s EFI 2.4 BP that was a seven petal unit. Matter of fact all of the EFI BPs that I have seen were seven petal motors.

[tlwjkw]

Yes they were. Tha BP and Oval Port CARB motors were 5 petal with tha exception of tha 2.0 champ motor (7 petal carb) I mentioned..........t

[shawn911]

what would a carb 2.4 bridge run on the vt rocket,with the foot work and a good set up?thank for all your help guys!!!

[tlwjkw]

:confused: Don't have a clue. No absolutly nothin' 'bout that boat...........

Bare aluminum block and heads, bare carbs out the front, 225 hp Bridgeport, I'd expect 85 with relative ease...

[shawn911]

that wouldnt be to bad,

I have a 93 Bridgeport EFI w/nikasil cyl. I didn't realized they still made them until I ran across this one.

There were quite a few Bridgeport replacement blocks and even some complete new factory powerheads manufactured and/or sold after '92-'93. I recall a couple of instances on this forum where someone has brought forth a Bridgeport with block dates in the mid 1990's.

[shawn911]

here are some numbers,block,01939913,front 969-9078-01,carbs 374-5427,intake 96770,heads 15221-c1,mid sec oc290021,12/3/91 power head is different from mid,what is this?is it a bridgeport thanks guys any info will help shawn

[tlwjkw]

Can't tell with my stuff if its a BP or OP. If thats tha date stamped on tha block it will be a '92 model built in '91. Only sure way of knowing is pull a head or tha divider plate. Ya might be able ta see tha bridge with a "snake lite" throught a spark plug hole. Never tried it myself, rather pull a head and be for sure with it............t

[shawn911]

hmm,ill check into it is there any to tell by pics?

[shawn911]

what is op stand for,sorry new to this

[pyro]

what is op stand for,sorry new to this

"Oval-Port." The early 80's (pre-Bridgeport) race motors had a large, oval-shaped exhaust port.

[shawn911]

Cool,would a 91 200 20in mid section,stock gearcase,with a 91 200 bridgeport powerhead worth 2000. Bucks its pretty clean

They over lapped each other in tha eighties.
Think tha OP was just a HiPerf 2.4 carb and efi and tha BP was a Mod-VP carb and efi. best I can remember.........t

Sure, if it runs good.

[shawn911]

All its suspose to need is the carbs cleaned,what would be some of the better mods to do to it.and would it be chrome or nik? And do you know if its good or not

[tlwjkw]

With that build date it should be a nic BP. No way of tellin' what kinda shape its in from tha outside. Regular comp and leak down will give ya a little information about it. Tha "it just needs tha carbs cleaned" never seemed ta be a good thing for me. If it ain't runnin'/runnin' right then its broke is tha way i look at it nowdays...............t

[pyro]

You should remove the heads, turn the flywheel and see if there is any visible damage to the bridges/Nikasil (BP) or Chrome (2.4 200) with each piston at the bottom of its stroke. A compression and leakdown test should tell the rest of the story.

DO NOT try to run it without completely re-building the carbs first. A dirty, lean motor will melt things down in a hurry.

Ah...so it's not just me. Pyro is right also. Don't run it without verifying the condition of the carbs. Expect the worse and hope for the best.
