This is the aftermath of a lower from a guy I know. Was cruising 55 mph and..

 

[82daytona]

That should buff out

Dam, Hope that's not a new dual down shaft drive.

 

[JD D05]

I was going the same speed when mine exploded.

 

[Singleton]

Looks like he hit something!

 

[hallett21]

Drive just blew? Or hit something?

Hmmm very pinion gear(s) 'sploding esque.

 

[ElAzul]

 

[Runs2rch]

Damn!!!!

 

[Waterjunky]

Just got to find the remaining parts. A little JB weld and good as new.

 

[Englewood]

Insurance will cover it.

 

[Danger Dave]

I always towed with my drives up to avoid this kind of issue.

 

[MagicMan]

Insurance will cover it.

Damn I always wonder about that, will my insurance cover a blown drive like they say. Anyone go through this?

 

[LargeOrangeFont]

Well look on the bright side, now he can try a different prop.

A buddy of mine blew his drive on his Eliminator and they totaled the boat. He bought it back from insurance after getting paid out and sold it with the blown drive.

 

[Melloyellovector]

That why I drive in 2 speeds, idle and fast. It’s that cruising shit that gets ya every time

 

[Outdrive1]

Crazy the way it sheared off. I’d almost bet there was already a crack spreading in that area. Just a guess

After draining the old drive oil, its always advisable to refill the drive with fresh oil before using the boat again! LOL

I bet the bang was pretty loud when it let go

 

[QC22]

Was he able to limp home? Holy fook!

 

[Constant840]

Why would the pinion explode?

 

[Rattle Can Lou]

Why the insurance questions...if he hit something maybe I guess..but if it shucks it's nuts..then I would think no insurance company will cover?? I think I'm right..it not I got a couple motors that look like that after I tuned them...gotta turn those in..

 

[HNL2LHC]

That is what happens when you beach it on the docks!!!!

 

[Keymyster]

He told you not to park on HIS beach!!!

 

[FROGMAN524]

What kind of boat was this on? What power?

Instant jet bote.

Like said above, Collision with something, insurance would cover it if you had collision coverage, mechanical no.

Saw this online...I've heard the rumors but I guess as long as you "hit" something?

I also recently heard of someone who got a new SCX and a teague engine rebuilt because he hit something under water which broke his drive and caused his engine to over-rev? This i second hand so it could be a story.

It's actually the new shaft-less drive. Everything is wireless these days

 

[Ragged Edge]

Why would the pinion explode?

Sheared a tooth from a lower gear, broken tooth got jammed in the gear set = explosion.

[J.P.]

Looks like and SCX lower to me.

 

[Bigbore500r]

No-tooth

 

[RiverDave]

It just exploded.. Did not hit anything

 

[Lavey29]

I was going the same speed when mine exploded.

It's not the speed it's the engine torque that kills drives. You have to make sure not to cruise in the RPM range where your motor makes its peak torque curve.

I think what killed mine was unexpected passengers on my boat for a 200 mile run, I had the wrong props for the weight and it was making max torque trying to get on plane multiple times. It really struggled to plane out.

That's true too. I used to take forever to plane trying not to rev the motor past 4000 and over torque the drive. Used to just slowly roll it over.

I think the 600SCI makes max torque at 3500 ( not positive) and it was just sitting right there for a long time trying to plane.

 

[WhatExit?]

Are those housings sand cast or investment cast or ? Failures like this could be a result (at least partial) of a defect in the casting

 

[Rayson1971]

Add that to the WTF wall art in the garage.

Yea that's not good. My Teague 825 was like 4400 I think for max torque back when I had it and never used to cruise in that RPM range.

 

[boatnam2]

Makes changing the oil pretty effortless.

 

[charred1]

Saturday? Big beautiful red boat? We just pulled our boat out of the water, at the Havasu Marina, as this boat was getting pulled out. Gave them a few plastic trash bags to to catch the oil that was draining from the bottom....was surprised there was any left considering he was towed into the marina...figured it would have drained out in the water? Felt so bad for the guy!

Exactly. They are sand cast.

This is why I went direct drive.

 

[RitcheyRch]

That looks expensive

Don't those Whipples have a bypass valve that reduces boost at lower load levels?

 

[Wicky]

Nitromethane is supposed to go in the motor, not the lower unit.

Insurance will cover it once... then drop you and you will PAY for this repair 10x over in the form of inflated premiums at the next company that will pick you up.. Unless its absolutely out of your means to repair , DONT file a claim...
I filed one marine claim in my life 2 years ago...... THE ABSOLUTLE worst decision ... That's my PSA for today.

Damn that’s a drag.
Are the boat, motor, and drive specs a secret??

Whole truth and nothing but. Spot on.
