big thanks to the cult at boyne thunder
 

Big thanks to tom (rock climber & crew) for the parts, knowledge, tools and help.

Thanks to sydways for the help and scanning my boat too.

Unfortunately despite all efforts we still wernt able to do the run.

There's always next year.

That sucks, What did you break??

We had a blast, sorry about your bad luck.

Brian - Thank You for grabbing my boat and putting it in the slip, greatly appreciated. Would have never made my sons baseball game in time with out the help!

#7 exhaust rocker got out of alignment and the pushrod came out of the dimple and up along side of it. Replaced the parts and its still missing.

Might be done for the season dunno yet.

weeeee, love boats!

Damn, aren't those fresh top ends/ rebuilds????

The rocker that got messed up had already been replaced since it was different than the rest. So It's happened before. Dunno how much of anything I believe about my boats maintenance history anymore. O well. Atleast ill know its done right from now on.

Tom (rock climber) had the exact same thing happen to his 525 too. Same rocker and everything.


Will see what ck motorsports figures out this week. Both motors might be going under the knife for some bigger power.

Sorry you had the trouble and let's hope it's not that bad.

Hopefully I can get it through the summer and plan the overhaul for the motors over the winter.

I see high 90's in my future!

Call Jimmy Vallako to do your heads. Guy is crazy awesome!

x2!!!

Man that sucks. Still plenty to do up there for fun I hope.

I tried, sorry I was of no help. My wife tells me that all the time!

Sorry to hear your troubles Jordon. Hope you still had fun!!

Actually the reason the pushrod came out is because the valve stuck in the guide. The 525 has a small amour of reversion on 7 & 8 cyl at idle. That causes carbon to stick to the valve stem and eventually it will stick, causing the valve head to hit piston and bend the valve. Common problem with the 525, they all do it, usually between 250 to 300 hours. Also the exhaust flange of the head will probably be very corroded. You are still missing because the valve is bent. The valve springs merc uses are marginal at best further causing this problem. When I do the 525 cylinder heads I hone the exhaust guides for a little more clearence. I also use a looser valve seal on the exhaust side to allow more oil down the guide. Coupled with a much better spring and retainer package.

yep that's what happened to mine.

****. How much we talking here? $$$$

The audience is growing...

Yes drew (remedy) knows what he is talking about and knows more about heads and engine building than most anyone. Had him do my heads a couple years back.

(DONT LET YOUR HEAD SWELL THOUGH :lolhit:

Head is coming off tomorrow. The suspense is growing...

Yea Drew, For a button pusher, knows his way around an engine. he'll have plenty to do on his many off hours!:lolhit:

Yup, 7 & 8, I think you'll find Drew is right on. Doug

No, it hurts because I have so much to do!!

I would like to knows where all these excess hours are... I seem to have lost them.

Probably your fastest, easiest way to get back on the water right now is to put the new Dart heads on. They are about half the cost of merc heads. Then later in winter they can be ported and do the rest of the package. If your heads are really bad (flange corrosion, guides badly worn etc.) It's more cost effective to use the new dart head. Before they came out w that head you had no choice but to fix them because the merc head is very expensive.

I'm not sure if it applies to your 525s, but there is a Merc service bulletin, deals with removing the lower bypass hose. Doug

What cc would I need? What kind of power increases will I see?

Give ma a call.

Jordan, here is the assembled heads pricing...

http://www.cpperformance.com/p-16621...assembled.aspx

I'll call you later today when I wake up homie

For that much money I think ill have my factory heads worked over this winter! Yikes!

That's actually not bad pricing... If your heads need a bunch of welding and machining to make them work... I suspect they will. I know its a big chunk to swallow, but that's the cost of having these toys. Beware of lowball quotes for your stuff... Usually its low and when they get into it, it goes way up. Most of the time when its done, you could have had the new heads.

+1, do it right the first time. you'll end up spending the same amount in the long run anyway. + you'll make more power

I thought the 525 used edelbrock marine heads. They are not that expensive...no need to buy anything from Merc

They are made for merc by edelbrock out of old beer cans. The 525 has a special exhaust flange bolt pattern, therefore the casting is different. An off the shelf edelbrock head will not work.

Hey KID any updates?

Yeah, shop finally called me back today after 2 days of trying to get ahold of them. There just getting to it today supposedly. Not impressed....

Is your boat at ck now? Sucks that your having problems with a newer boat. Keith is always busy and has some serious hardware coming out of there.

Nice meeting some of you A/T owners up there at the BT event....nice showing with all the A/T's I saw and finally met some of my long time A/T brothers up there for the first time. I saw the 33' A/T sitting at the dock as they tried getting it to work, etc,....sorry you guys missed the run....what a heartbreaker----really nice looking boat though!

Thanks. She did looks sweet sitting there! I had been looking forward to Boyne since I picked the boat up. Very disappointing is an understatement.

damn kidd...sorry to hear you had issues at the run...hope you get your A/T running right soon. You guys summers are a little shorter than ours.

go ahead and Whipple the 525's while your at it!!! you know you want too:evilb: :cartman::party-smiley-004:
