Blown motor update??!!!

[tailwalker]

Well I got my motor back from the shop and installed it. I had a pro mechanic do the start up so it would be done right. We primed the motor with oil and a beak in additive provided by the machine shop. We got the motor started and ran it for 40 minutes at 2000 rpm. Things weren't sounding right to me nor the mechanic.....So i put on a new electrionic igintion and a new carb and went for it again. Things were sounding bad...back firing out of the carb.......the cam had gone flat sending metal through out the entire motor:passout:!! Have you ever been kicked in the, well you know, and your laying on the ground in agony and while your on the ground another guy goes ahead and kicks you again in the same spot like he was trying to make a field goal?? Well thats about how I felt....bad. I called the machine shop and they said bring it in:passout:. That means take in out and bring it in.......oh god.......well I took that thing out in about 3.8 seconds with a few good ole cuss words and took it back to the shop where they tore it down and rebulit the whole thing all over again.....I just picked it up today and will install it tonight and hopefully have a successful break in:pray:. This whole episode started in May. So needless to say I have been shamefully bumming fishing trips from my buddies and a few Ifishers for the last several months. I will give you guys the update....soon....very soon!

Wow ... That sure would of taken the wind outa My sails ...:passout:
Glad the Machine shop stood by there work ,,, :applause:
But what kind of additive did they give you anyway ???
Not to say your mechanic does not know how to break in a marine motor but this is how I have always done it ...
Consistently slow speeds are not necessary to break in your engine. Warm the engine thoroughly at approximately 1000 or 1200 ... then up to 1600 to 1800 if desired ,while underway vary the R.P.Ms don't run at a constant one for extended periods , short runs not to exceed 5 minutes can be made at 2500 the first 5 hours, the next 10 hours short runs to 3000. Work to higher R.P.Ms gradually with short runs at higher speeds until 20 hours are reached. Then change the oil and inspect the motor mounts and manifolds for loose fasteners etc ... generally give the motor a good going over ...
Then runer like ya stole er for short periods for another 5 hours and then just run as you would normally ... Oil changes every 50 hrs .

Just so you know your not alone, I dropped mine off at the shop on 7/22 for a complete rebuild (has #6 postion disingrate), was supposed to get it back in 7 to 10 days. For one reason after another, it kept being a few more days.

Every night I drive by the river and it looks soo nice. Keep telling myself only a few more days (for 6 weeks now). On saturday the Mechanic calls and has my engine running in the back ground. Wants to tell me everything is a go and I can pick it up Sunday. I went to sleep with dreams of fishing and running the river in my head.

Call the mechanic on Sunday morning to pickup the boat that night. He says everything is a go, all he needs to do is the final compression read outs and paper work for my warranty.

An hour later I get a call that somthing is wrong with the boat. 3 pistions cracked on the new motor and cracked my new block... back to square one.

Later,

Chris

Dang its an epidemic ...:bigshock:

Sorry to hear the bad news, but it confirms what I've said to people in the past.

Newly rebuilt means that the motor broke down once and is likely to do it again...probably sooner than you would like.

I'd rather have a motor with an average number of hours on it than a recently rebuilt motor with low hours.

There are exceptions to be sure, but I'm going to bet on the motor that has never been opened up for repairs.

CAN YOU SAY CRATE MOTOR?????

I fell bad for you guys- that would definately leave me majorly depressed if i was in your shoes.

I have to say that given the choice, i would opt for a crate motor. Failure rate is usually less than 1% and you can order most knowing how many horsepower you will get. They typically have dyno-ed that power combination and have it down to a science.

Making a motor is like baking a cake, proven ingredients and a cook that knows what the hell he is doing.

Good luck guys. hope thing improve soon:wave:

Not really an option on a 175 SJ...

Although if the mechanic doesn't get his #$)( together and get the boat running by next week I am going to just order a new engine from Merc and put it on my existing pump...

Thanks,

Chris
