Sorry Dude...

[red_n_vegas]

Well when you buy an older boat things like this happens. I guess I will not be at the lake for a while...(unless people have room on their boats) Sat I will pull the motor out of the boat. So hey does this make me a Hot Boater?...J/K http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif Ken I will also call around for the parts and see where the best prices are. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif

[jkpruitt]

Don't you need to know what parts you need first?

uhhh Duh...I think that might help... http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/confused.gif That’s what you get for being at work in a meeting, looking at this site and thinking about your boat all at the same time http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif

misery loves company...I got a whole 9 hours on my motor before my cam went flat last weekend. Â*After waiting for 3 months for my boat, I'm again boatless...for atleast 3 weeks. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/sad.gif Â* Looks like its time to hit that honey-do list...

Yes, you are definitely a Hot Boater......

If you need some help, let me know. I'm on vacation and my home projects have about come to an end.. I live up here on the North side of town..

Good luck...

[red_n_vegas]

Hey Mo..Ken and i just got done putting in a crane cam in mine...what do you say we go have a beer or 12? How did a new cam go bad so soon?

[Trouble Maker]

Is it a flat tappet style set-up? Â*If so, it probably wasn't broke-in properly..... Â*After installing a new cam and lifters you need to let the engine run above 2000rpms for around 20 minutes. Â*The lifters probably weren't rotating on the cam, which will cause them to wear out quicker than shit..

Good Luck......

[red_n_vegas]

Mo is that cam under warranty?

[red_n_vegas]

T.M. thanks for the offer I will keep that in mind. Ken is going to help me find where the problem is. I do have one question....Got a spare motor I can use....J/K http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif the hardest part about the whole thing is finding the money to fix it. I guess I will be working a lot of over time http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/sad.gif

[Trouble Maker]

I totally understand.........

Another sign of a true Hot Boater though......

Keep us posted

[Rude]

red and mo, sorry to hear about the motor probs.....THAT SUX!!! keep us posted on your progress and i'll be glad to help if i can.

[its all good]

red, the offer still stands if you need help , let me know. Bob

TM's right about the break in procedure and this cam was broken in properly. Also, I was completely babying this motor...completely following mercruisers own break in procedures for the first 20 hours. They say change the oil/filter at 20 hours, I did it after 4 and 8. The problem has to be 1 of 2 things: either there is something wrong with the lifter bore (very unlikely ) and the lifter is sticking or there is something wrong with the springs (more likely ). I think the wrong springs were used (part of the complete comp cam valve train kit ).

Cams can just go flat (almost always during the break in period as my first one did ) but to have 2 go is unusual unless the problem is elsewhere (like valve springs ).

RNV, I'll drink to our plight this weekend as our friends are tearing up the waterways and I'm home running crown and painting http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif

[Red Horse]

My boat is not very big, but I do have 2 seats that yall can ride in if you want. Let me know

[jkpruitt]

What do mean "went flat" ?

[MOWtown]

Horse, thanks for the offer. Â*Maybe in a few weeks if I'm not floating by then.

Ken, during the first motor initial break in (on stand ) one of the lobes went flat within 20 minutes. Â*I know that all cam mfgrs will say that it's always installer error that causes a cam to lose a lobe but I have about 4 hot boat (here we go again http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif Â*) or drag car mechanic friends who will swear that there are "bad" cams right out the box. Â*

However, since this problem has occured now 3 times Â*http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/wow.gif Â*I am much more likely to believe that my problem IS installer error. Â*The first time, the mechanic sent all parts to machinist for machine work, block test, etc. then the mechanic put it back together himself and the cam "failed" in 20 mins. Â*Then he had the machinist tear it apart, replace bearings and rehone the cylinders to make sure that the cam shavings hadn't damaged anything and the machinist put it back together (long block ). Â*Same problem in 1 hour. Â*Machinist did all this again and it failed in 9 hours. Â* Supposedly, it has not been the same lobe all 3 times so I think this is a valve spring issue (too much spring pressure ). Â*Your thoughts...(skip the obvious answer: get the motor away from these guys, I'd rather avoid having to sue them for my money back plus my lawyer says that I still have to give them another chance to rectify the problem since I technically have had only 1 failure while having the boat in my possession.

[Ratacole]

Mike,you wan't a ton of spring pressure to keep your valves shut & from floating (I run a ton with a rev-kit). Have you thought about a roller valve train? It may be an oiling problem. Thats my .02 worth. Mike

You have a bad block. I have had (TWO) while racing, both doing the exact same thing. Wearing the same lobes off the cam within an hour of engine time; although my engines were only running hard for (EIGHT) seconds at a time. In both instances, I trashed the block; blocks are cheap.

[jkpruitt]

Unless you guys are turning a lot of RPM: 7000+, why are you running super heavy springs? Because someone told you you needed them?

[kevnmcd]

Yeah, huh? http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/wink.gif

You know, that crossed my mind because I have read of poorly cast blocks with alignment probs but the thing is that I have NOT had the same lifter/lobe go out each time. Â*Also, this block was fine prior to my cracked head. Â*I never had any lower end or valve train problems before the rebuild. Â*

Re: the heavy springs. Â*That's my point, I did not spec out the bigger high perf springs. Â*I'm using a Comp 280 cam and supposedly the valve train to go with it...nothing very radical. Â*I think that the springs provided might be wrong.

Mike, I considered roller lifters but I've heard that they don't do well in motors that idle a lot...in other words, they're meant to work hard. Â*I do a lot of night cruising and idling (and something else http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/wink.gif Â*). Â*Do you agree? Also, that still doesn't explain what's going wrong. Â*I want reasons before I start changing things. Â*Right now, the only positive thing is that it's entirely on someone else's dime.

BTW, this is exactly what I was trying to avoid by selling my "hot boats" and buying a "performance boat". Like someone else said, I'd just like to be any kind of boater right now http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/crazy.gif http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/laugh.gif

All you guys having engine problems and hull cracks makes the little problems seem even smaller. The rest of us should just be thankful we are able to get on the water.

Best of luck with everything. If I can help, let me know.

Ken.
