Wow!! That was scary just watchen knowing something bad was going to happen. Why did it blow out like that ? Video said it had a merc pro et lab finished prop, so why would it loose bite? I run my Action hard with a merc et prop and never even think about blowout! Now it will be on my mind next time out but how do you stop it from happening ?

Maybe he should try a Bullet, Stroker or an Allison next.

Look in the "Photos and Videos" Forum. The guy that was filming posted it there.

What a DOG 400 hp and 106 mph ... on the edge:nonod:

maybe gearbox was way deep so slow and blows out?

[patchesII]

He raised the engine too high

[racer]

Larger gear case on that engine so blow out will be different. Standard dia prop on big unit. Engine height are some of the reasons for blow out not to mention trim angle.

how do you get blowout with the box too high, I would have thought too high has the bullet clear of the water?

[pappa pete]

Blow out is the prop losing thrust, motor too high prop is surfacing, too much height at speed prop runs out of water, simple

I agree with this 100% That boat acted like the motor was trimmed out of the water and had no rudder at all? Maybe this boat wasn't designed to go 100mph??? 400hp outboards on bass boats...it's a whole new world, unfortunately these two guys may have learned a lesson for all of us, just glad their OK!

Once you get it repaired they should try it again I'm sure they can give it to 104

Years ago I took a boat over to Monty, I had it looked at by two local shops, no one could get it right, I called it my salt water boat it had a old 90's stock 225 Johnson, (I've never put any of my 2.5 stuff in salt} the only mod is some epoxy in the float bowl area, In no time Monty went thru the carbs and said lets go for a test ride, he installs one of his props, goes for a 5 minute run, says its a honest 100 mph boat GPS showed 99.7 , the boats always rock solid, it has a flat 11.5 pad.
Now this boat has a 400 hp and did 102 mph, I know set up and prop is important but golly, Shazam , those two are so lucky to be OK.

Yes I seen this last week on my YouTube , kinda wild the way it happen in video. Didnt even look like boat got stupid , when a blow out happens wouldnt the nose drop

55 seconds from 90 to 102 is a long time to try and eek it out and make a mistake ,lucky dudes for sure,400 hp should be running 100 easy with neutral trim ,not impressed to say the least in 400 r

[JPEROG]

I have yet to see a "single application" with 400R that impresses me. I do know of one coming together that will, but until he is up and running, the new 300R will run off on them. As mentioned above, if they had a pro-et (which is a 14.5 dia. propeller) and the 5.44 case, its a mess waiting to happen. If you are going to play with a fast V-bottom, keep it hooked up.

Two lucky guys, glad no one was hurt.

At the 2:22 mark in video he states he has blown it out more than 20 times!! That's crazy, sounds like he had plenty of warnings this boat was not running right. No way would I continue to run a boat that blows out like that until I figured out what was causing it to misbehave! I guess he learned the hard way that he had a misbehaving boat!

[FUJIMO]

have no idea what this boats rigging details are...but the gearcase could simply have a case of the "crabs". and blow'n out cuz of it. who knows. agree with the prop diameter thing.

[eli]

5.4 gear case is like dragging brush thru the water

[Scream And Fly]

That video is a scary example of what could happen so quickly with no, or very little warning at those speeds. It seems that not too long ago, 100mph for a bay/river boat seemed like breaking the sound barrier. Now it's commonplace, which is just an example of how powerful production outboards are and how hull designs have evolved. I'm glad that this did not end as badly as it could have.

Yes, and when the bow drops suddenly, you get drastic bow steer and the stern comes around because the skeg is no longer in the water. If you look at the video, you can almost see that happen.

Ya looked like it went right when it happen, I know my boat has lots bow steer like that if motor is to low when I let off gas , can get hairy
