That boat is awesome. We'll done. I have a Glastron 1900 with the exact same outdrive, threw out the old V6 and busy modifying a Lexus 1UZ-FE into it. Also added twin turbos for excitement.
Go with a mirage plus prop. The “plus” means has a good amount of bow lift. Over 70 you will want to consider a nose cone on the outdrive and if I starts to chine walk a set of tabs or correct prop will help with that.
My SBC 452hp 383 stroker with an alpha would run 72 on gps with a 202 Lpx Crownline! Love it, figured you’d get a few more mph out of it. I ran a 22 pitch enertia. I did that swap ten years ago.
Thats amazing would love to do the same thing. What outdrive most dont like being shifted with motor over 600-700 rpm. Is it raw water cooled what motor did it have befor. Love this wanted to do this swap sence the day i bought my boat 5 -6 years ago the carbed 4.3 still going strong lol what prop size
All good , Fast ; but why in the hell would you put nos on a non drag boat ? Tune the motor match the prop. Good to go. ! vs 15 sec of rod popping through the block and may be through the haul ? Just a thought . Cheers
Awesome! I’m working on my swap right now. How did you guys do the exhaust? Is it through the alpha Y pipe still or did you run it through the transom somewhere?
I wired the interrupted switch into spare input on the holley and set it up to trigger the 2 step rev limiter. Then Set 2 step rpm to 400rpm. It's just enough to to get it to dip but not stall out.
@travtech1 tried this with my carb MSD setup, but it will only allow a minimum of 2000 rpm. Many people are turning off 1 bank of coils momentarily to allow the engine to stumble and fall out of gear.
Boat engines have must a lot more cam lift and duration on them so they don’t like to rev very high and make most of their power lower in their power band. Most high performance boat engines and outboards rev to 6500 rpm max because they can hold higher rpm’s at wide open throttle for longer periods of time without stressing out the engine. Higher rpm’s put a lot of strain on the valvetrain and it becomes harder to keep the engine from overheating. Of you cite race engines do that just know they get rebuilt every race. These engines get rebuilt after 200-300 hours for high performance engines and 500-1000+ if they are regular boat engines.
Why is the tuner so focused on a 100 shot of NOS. (Idles to high 100 shot) (It runs good 100 shot) ( it runs runs bad 100 shot) Thought this was a nitrous video
DEFINITE IMPROVEMENT OVER THE TYPICAL GM BOAT ANKER ENGINE'S THAT SUCK ASS. NOW IMAGINE A HIGH RPM 5.0 FORD COYOTE ENGINE IN IT. IT'S ALL ABOUT PROP RPM'S REASONABLY SPEAKING. NOW IMAGINE A 10 SPEED 10R80 FORD TRANSMISSION HOOKED TO IT. IT COULD TAKE A BIGGER PROP WITH MORE PITCH, AND THAT TRANSMISSION WOULD BE IDEAL FOR ALL SCENARIOS !. POWER FOR JUMPING UP ON PLANE QUICKLY, TOWING POWER, HIGH SPEED, LOWER RPM CRUISING SPEED, FUEL ECONOMY, LESS WEAR AND TEAR. THE LIST GOES ON.
@@travtech1 I CHALLENGE YOU TO EXPLAIN WHY. ASK YOURSELF WOULD YOU OWN A CAR WITH ONE FORWARD GEAR. BTW, A PERSON ON RUclips DROPPED A TURBO CUMMINS ENGINE IN A BOAT. IT WAS SLOW. THEN HE HOOKED AN OLD STYLE AUTOMATIC TRANSMISSION TO IT WITH I THINK 3 FORWARD GEARS. NOW IT DOES OVER 90 MPH, AND JUMPS UP ON PLANE QUICKLY.
Pretty nice work guys. Im curious though, why start with crappy hull? If you put all this in a fast by design hull you would be making impressive speed numbers and have a much cooler boat in the end. Bow riders are for kids
My last boat was a closed bow eliminator daytona 25' cat with twin turbo stroker bbc. So I get it. My family enjoys this boat and it works well for us right now.
@@travtech1 looking forward to seeing what you come up with next. Again good work didnt mean any disrespect on hull choice. You have your reasons for it.

Your boat probably had the 5.7 v8 1.48 outdrive ratio mine has the 1.81 v6 ratio that's how you were going faster with a 22p vs my 25p
@@travtech1 you’re are exactly right on the outdrive ratio… my 202 LPXs running surface wasn’t hydrodynamic at all…
@travtech1 how did you wire your shift interuppter?
With bigger cam do you have to worry about water getting sucked in. What manifolds bad boat and one of the best tuners there is

Why would you put in the music to the video, when the engine was making a much better sound.
You should build one the. You can make your own videos

That thing rips!! Good job on the install and tuning! Can’t wait for you to re-prop and add nitrous!
Some of the previous generations of laser boats had a bravo 1 X with the 350 Chevy MerCruiser,, which is a 600 horsepower capable...
Awesome! I’m working on my swap right now. How did you guys do the exhaust? Is it through the alpha Y pipe still or did you run it through the transom somewhere?
Nothing better then drinking and driving
trasmissione installing?
Dude that’s fast
The boat was coming up off the water
@travtech1 how did you wire your shift interrupter ?
That’s a great question. I had issues on my old Caribe boat. It’s tough to get it timed just right.

I don't have a tuner that I can take out with me for the day, I don't know shit about tuning.
Should I just go Term X and forget all this?
Cam specs????? I have a very similar setup and will be doing a cam swap on my boat sometime....
225/230 114+2 .615"
@@travtech1 awesome, I was looking at the summit stage 4 truck cam, very similar specs at 226/230 112+4 .550"
moving out pretty good definitely has room for more speed.
Can we all give it up for the Sombrero?
That alpha one is tough lol
Get a bow lifting prop. Probably a 28" 3 blade chopper should do the trick.
Just picked up a used mercury tempest plus 14.6x27p I'm going to try it this wknd.
I know your not drinking beer behind the wheel but drinking beer none the less. Your motto: Boating and Drinking do mix
Wonder how a gt3 engine would run in a boat with 9100rpm. With a turbo straped to it.

@puttingwarheadsonforeheads9872 ya i figured it wouldn't be the best option. Just thought it was a cool idea if at all possible.
Super cool build, but man you guys desperately need better audio recording
Sucker rips for a cheap setup. Gonna have to scroll through marketplace now lol 😆

(It runs good 100 shot)

Bad ass
I love the sleeper boat
Needs more prop
No music/on emgine
it'll go faster if you unload the 576 pounds from up front
No honey I won’t do NO2 lol
Boats really are the cheapest engine dynos....
*compared to actual engine dynos... break out another thousand
Boats run faster in chop and slower on glass water

I think it's awesome to see a bowrider doing what this one is doing. Proper sleeper.
OPEN UP THE ENGINE BAY FOR HEAT EXIT, AND GO DRY HEADERS. WET HEADERS / EXHAUST SYSTEM ROBS POWER AND POLLUTES THE LAKE !.
THE WET EXHAUST SYSTEM IS KILLING YOUR HIGH RPMS. 5400, DON'T THEY REV TO 6000+
We were seeing 6400-6500 rpm. The old smaller cam we only ever saw 5900-6000 rpm
