Well finally is m back and on vacation so started digging into the engine. The shop which pulled my engine told me I had a bad crank and bearings. So I got it in the garage on the stand and it is completely down to nothing. Sure enough crank on the main bearing is gouged out and all of the rod bearings show wear and dis colorization so they are shot. I am going to pull the cam bearings along with having the crack inspected at a machine shp to see if I can have it repaired or end up getting a new crank. Everything on he internal side of the engine looks really good. Externally the surface rust is a bit much but nothing that a sanding and fresh coat of paint will not fix. I will get some pics posted tomorrow after I work on it for day miner three. I have to work four days over the next three weeks so I am hoping to get the engine done and tested to ensure its safe. My new mantra is to make it right because it's a little difficult to gt out into the Gulf of Mexico and worry about the engine. So I figure if I do the work and take my time to do it right I should not have any worries. :watermelon:

Ayuh,.... Look into a Long Block rebuilt/ re-man replacement,....

It's probably Cheaper, 'n no doubt quicker to go that route,....

Yeah I am sure it is a lot quicker. Not really sure about the cheaper part. I have been looking at getting a replacement for a while since it has been sitting int he shop. I have over $4000 already invested in this engine so I am going to go slow and do it myself along with help from here and the guys who work at my unit who do this for the navy. I am hoping to come out on top without breaking the bank.
The enine is completely tore down and in my garage so will see. I dropped the crank off at the machine shop wtg on word back about that so I can that part straight. Have to go pick up cam bearings and hope that I have the tool in the shop at work to install them. Will see tomorrow whe I go in. Well heading back out into the garage to get some work done check in later with pics!

What kind of stuff do you have invested into this engine? $4000 could have got you a long block easy.

This was a restart to my first post since it has been too long to add to it....
The bearings went out due to water intrusion in the engine....I had the engine rebuilt/built have you at a shop in Chesapeake va. It cost me $4000. I left for deployment the day after I got the boat back from the shop and the boat sat unused/tested for 321+ days. I finally got to put it in the water and the raw water pump failed, replaced pump and half way across the Chesapeake Bay a hose split from the water pump and filled the bilge with water. I waited for the pumps to remove the water corrected the hose issue and I had to creep back to port.
I checked everything out and found I had water in my oil so I changed to oil 4 times before i tried to run it on the water again.
I finally tried to run it and when I got it out in the harbor it would not come up on plane and the engine sounded like a Volkswagen (the old ones). I trailered the boat and towed it to Picayune Mississippi where I was transfered to and had a shop pull it and give me a diagnosis of what the problem was.
Found out it was the crank and bearings.
I took the boat and engine back home and tore the engine down to see what I can do.
Where it stands right now it's in pieces in my garage minus the crank which is at the machine shop and I got a call from the machinist and told me to trash it and get another one. He said he may have one in the shop,and will let me know later.
I am in no rush but I do have plenty of cash already tied into the engine and want to do what I can to solve the problem. I have access to some of the best equipment he Navy has to offer as well as mechanics that are helping along wit the guys on here I am hoping it all goes better than my previous efforts.
I take all word of wisdom given so thanks in advance.
Joe

No offense but it is really hard to read your post. It is missing lots of letters. At any rate, at some point you have to cut your loses. A long block and new manifolds/risers may solve your issues.

Sorry about that Ipad keyboards suck...but anyway I took my tore down block to the machine shop and he is saying the same thing that I am hearing here to trash the engine and get a new one. Now I have a few options that I want to run across you guys.
Option 1: The shop that diagnosed my boat said he has access to a 350 with 40 hours on it that he will pull which has everything attached it will be a swap job from one boat to another. I will go see if I can get pick of the engine and post them. $3500 plus $600 installation into my boat. (HE said he would give it to me for what he is paying for it)
Option 2: Slidell Marina who does a lot of business with my unit has told me that he can get me a brand new mercruiser long block (not reman) for $3100 but I would need to swap all of my attachments from my engine to the new long block and he would reinstall the engine and help me get it straight.
Option 3: The machine shop that looked at my block and crank said he can build a long block in his shop for $1800. I would have to do the same as option 2 for the installation. He is a very reputable machine shop that builds race engines all year long he was referred by another contractor that works on my units SOC-R boats.
I understand that I will have to get new exhaust and risers since I am finding pieces of them in my heads as we speak and I am really trying to do this the right way without any shortcuts. I am cutting my loses and dealing with it. As they say at my unit "Embrace the suck"...
Thanks

I would go with a new long block from GM. You can get a 4 bolt, 1 piece rear main long block for around $2,000. Summit is one place that sells them. But you can shop around. You would need to swap your old externals, but you would have a new engine with a truck cam, (which is appropriate for marine use), stainless steel heads gaskets, and brass core plugs already good to go.

Yeah I saw those a while ago when I was looking. They sell First Mate engines which is one that the shop here installs. I am looking at the price to replace the exhaust and risers while I am at it so am crunching numbers now to see what ave I am going to take. I have searched to the end of the internet for engines and there are so many that are available and the prices are relatively close.
Thanks

I would make the move to upgrade to Vortec heads at this time........you will need a Vortec intake also.

I believe it was 96. I do know it was mid 90's somewhere for sure.

Ayuh,.... The 1 piece main seal is '87, Vortec is '96,... roller cams, 'tween '87, 'n up,...

Re: 1998 Rinker 242---5.7 EFI (thread restart)

I was chatting with a salesman from a engine distributor online and he ran the casting numbers for my block it turns out the rebuild was done on a truck block.
If someone could explain to me the difference in Vortec or non vortec because he told me that my engine is a vortec due to the intake being a 8 bolt? There are 2 bolts in each corner of the intake he also told me that the engine was 300 hp not 260 hp as I was informed. Now I am getting really confused. I have the serial number from the original plate that came with the boat 0L093092 this is the number I have been using to locate parts and such so any help is appreciated.
Thanks:embarassed:

That clears, GM started in 86 and Merc didn't start until 96. Was just reading on the vortec heads in chevy mania is where I got my dates. So it looks like the OP should have vortec heads

Edit: look here

What are your head casting numbers

Vortec Cylinder Heads

10054727 is the cast number on the block. Looking it up it is a truck block so the guy at the shop in Chesapeake did not do me any favors when I paid for a rebuilt marine engine obviously.
thanks
