Damper Plate Failure

[wakesurfid]

Any history of Drive Plate/ Damper Plate failure on the Tige V drives?

Its not too uncommon on Malibu and Mastercraft

Did Tige boat use the same flimsy damper plate in the early 2000's that caused these failures?

[NICKYPOO]

I've never heard of one.

The main cause of failure is either to fast of an idle or rapid movement of shifter from forward to reverse with hard excelleration , or lots more extra ballast weight , other wise we havent seen that much failure.

[boatwakes]

Tige did not use that POS drive plate but interestingly the same driveline packages were offered in the other boats. I'm not going to begin to speculate why, but thank whomever, great decision. The enclosure surrounding the springs on the bad units lead to extensive corrosion which translated into destruction at speed (under load). There are some really awesome pictures of some really destroyed bell housings floating around due to that problem.

The damper is determined by the engine manufacturer not the boat company, if a particular brand engine was failing , it would fail on any brand with that motor, I cant really narrow it down to any particular brand because we have had every brand fail, again we havent seen that many failures , most common was on the higher torque motors like 6.2 hammerhead, normally you had plenty of warning when it was going bad , they would rattle like crazy when you were idling in gear and the noise would go away after you powered up.

[boatwakes]

These are the units with the destructive failure issues http://www.correctcraftfan.com/forum...-plate-failure so everyone has a visual. All damper plates will fail over time, usually beginning to rattle and chatter, but not like these loose pin grenades. The engine manufacturer does not decide which damper plates are bolted to their engines but rather the transmission manufacturer. Im only speculating but I think someone came up with the enclosed spring idea after drinking and smoking too much with too little experience in marine environments and then pitched the idea to zf and PCM.

Marine power dampers are incapslated in rubber around the hub and springs , ive got 1800 hrs on my ski team boat that pulls tremendous loads no failure so far , our team just set a record for 9 guys doing a 360 around the boat you should hear the engine strain.

I think you guys jinxed me. Literally the day after I read this thread (i.e. Thursday) my damper plate broke on my new (to me) boat. I was surfing at the time, but those in the boat said it sounded like the engine fell off or the transmission exploded. I guess it was loud. They immediately cut the engine, and of course when restarting and trying it, there was no driving it. Another tow back in, and a couple days (including the weekend) in the shop, and we got the diagnosis today. Boat won't be ready until Friday. Mechanic said he ordered a more heavy duty plate than the one that was in it. He also said there was rust and corrosion on the one that failed. Is the corrosion thing normal? It seems the part shouldn't be exposed to moisture, but what do I know?

This was after having the throttle handle fall off a few days before...and in the process, severed all the TAPS wires, etc. That was fixed for a day when the plate busted.

For what it's worth, the mechanic corroborated the sentiment here; the damper plates don't seem to fail that often. Lucky me.

Bill,

Can you post some pics of the old vs the new plate?

Also, how many hours, and what prop?

[billwil]

I'll see if I the mechanic still has the old one...it's supposed to be done tomorrow, so will be taking it out (fingers crossed). Low hours...but that means it has sat a lot. It's a 2003, and when I bought it last month it had about 260 hours. Trying to work all the kinks out by running it...often.

[billwil]

Ok...turns out the boat didn't get finished today because evidently the part didn't come in until today. Shooting for Monday. Bummer, but I did stop by to grab some photos. Oh, and the prop is an ACME 381 (I have the 6.0L engine).

Here is the failed plate (notice all the broken springs/brackets sitting on top):

And here is the new part that will go on:

I'll ask again in case anyone knows...why would the old plate have corrosion? Shouldn't it be sealed in the bell housing of the transmission? I've seen pictures of others that have been corroded, too, so I guess that housing is not all that well sealed, and certainly isn't keeping grease or something on the parts.

[wakesurfid]

Wow! That's a lot of rust. I changed out my damper plate in a 2001 Malibu and it looked brand new. Was the boat near the ocean? Kind of scary if the springs could rust. Do you see much rust in other areas of the engine?

[wired1236]

What is this coating u? I'm pretty sure mine is on its way out. I have the rattle happening when idling in gear. I've checked the timing, RPM at idle and can't get it to go away. I was told around $600.

[billwil]

I don't know...the dealer is handling it as I just bought it from him. I'll see if I can find out what it would have cost.

[Stingreye]

Bell housing is not sealed and has a slit to let water drain. My ring gear corroded and boatwakes replaced my damper plate at the same time since the motor was already out and it was fairly inexpensive with the motor already out.
