trigger plate assembly broke? am I right about part name?

[boatin-on-cherokee]

Mercury 150 XR2 - Had a new stator installed and they set time. Didnt make it across the lake and it quit. The new stator didnt make it at all, and only on the water for about 10 minutes. The bracket that the stator bolts to - is this the "trigger plate assembly"?

Well, it was cracked. What causes this to crack and what am I looking at to fix?

The casting that the stator screws to is the upper main end cap if your taking about item 13-- http://www.mercruiserparts.com/Show...&bnbr=100&bdesc=Cylinder+Block+and+End+Caps-- and if thats what broke someone did not install the stator properly.

Thank you for the response Laddies, the mechanic told me that there was a crack in it, and he went ahead and broke it off and was said he would have to 'split" it and check the bearing?

Am I getting shafted here or what?

Or would there a 'bearing issue'???

Re: trigger plate assembly broke? am I right about part name?

It's real hard to say without seeing the part but the fact remains that if it was broken when then engine was in the first time WHY was not any thing said about it, it apparently was quite obvious then it was there the second time. Why would a mechanic break a casting that is NLA from Mercury without the owner being advised first. It certainly looks like someone is trying to cover something up here. Are the stator and flywheel damaged it would be hard for a casting that is correctly screwed to the stator and covered with the flywheel to crack from normal wear and tear. In 40 years of repair I have never seem a upper end cap broken even when the crankshafts have broken in number 1 or 2 rod throughs.

Thank you again for your response. Here is the part he broke off cuz he said he wanted it out of his way, and now they are saying it will be two to three weeks before I get my boat back.

I think the image is here now.......

Well it's definitely broke, if it were broken the first time the boat was serviced there would have no way to tighten the stator back down as it's broken in 2 of the retainer hole for the stator so I can't say why or how he broke it but the only way it could have gotten broke is someone pried on it there is one piece missing out of it it looks like so if it broke while the engine was running the flywheel or stator would be skinned up. There would be no reason to even to be under that flange unless you were trying to remove the trigger as the stator simply sits on top of it and is aligned by the flange and held in place by the 4 screws. Wish I could help more but if he is going to charge for the repair I would pick my stuff up and find a reputable marina to repair it.

Re: trigger plate assembly broke? am I right about part name?

The mechanic called me and told me that the housing was cracked, but said that he had it fixed and also said that the housing was cracked. At that time, he said that it might run for five minutes or run forever and said that it was my choice to take it, or have him keep it for 2 to 3 weeks. All he had done was replace the stator and replaced the diaphram and charged me 588 dollars. I decided to go ahead and pick the boat.

Well, I never even made it across the lake, I had it back at the shop the next morning before they opened and left it there. I went back about 30 minutes before they closed to see the progress and he said he had been on a service call all day and all that had been done was the flywheel was off and he told me that 'he broke off' the piece that was cracked. While I was standing there, he took a long screwdriver and hammer and pried it up and broke the piece completely out. Then he said 'he might' get to it on Monday, saying that he would use 'used parts', to save me some money.

What should I do?

Re: trigger plate assembly broke? am I right about part name?

As the story evolves I think that I would let them repair it because they have a used part that is NLA so they don't have to search for one, they did the original repair and told you the part was cracked and the most important is that as long as 2 screws were holding the stator and it was not hitting the flywheel thats not what caused the engine to quit.

Re: trigger plate assembly broke? am I right about part name?

OK,

So, what could it be to cause the housing on that part to crack? Are they going to have to 'split' the motor? Is it a bearing that can cause that to crack? I looked at the parts link that you posted for me in an earlier post, and it showed bearings in there, could that be the problem?

Re: trigger plate assembly broke? am I right about part name?

Some thing caused it to crack and the bearing could be bad but I don't believe it cracked the housing the only thinh that ataches to the housing where it's cracked is the statot and it's dead flat on the mating surface.

Thank you for your quick response. Do you think that they are doing un-needed work?

Re: trigger plate assembly broke? am I right about part name?

1. About the only way that part is going to crack or break is for the wrong stator to be bolted to it, which should be very obvious to the one doing the bolting. Some shops will even cut a notch out of it so they can get the trigger wiring out without unhooking all the wires (when doing a major rebuild) and it causes no problems. It got broken by the mechanic,

2. They seldom break, even if the power head grenades, so they are pretty easy to find and procure.

3. On a 2.0, 2.4 or 2.5 v6, the power head does not have to be split to remove the top bearing carrier. You just unbolt and remove it. It is a slip fit sealed with O rings.

4. If it were mine, I would reclaim the boat immediately to avoid further damage.

hope it helps

First I want to thank those that responded to my post.

Here is the final word. The crank was bad, they tore it down and there was a groove in the top of the crank that caused the problems. As I have learned, 'and please correct me if I am wrong', that the end cap assembly should slide right out after the flywheel and stator are taken off. It would not slide out due to a 'large' groove at the top of the crank.

The shop has offered me another Mercury XR2 150 Blackmax, which they say is in excellent condition for 2000.00, they will take everything that is left of mine and put this other motor on and have me back fishing for 2 grand.

So, the story now ends........thank you, those who responded.......
