I wanted to get some thoughts from you guys. tomorrow we are signing the papers for our new to us boat. We planned on buying a new crownline 205ss but than found a deal to good to pass up. The boat is a 2014 Monterey 196ms with 28 hours. Only downside is the engine is the catalyst. It has the 4.3 in it which I like over the 4.5 just because I'm familiar with that motor and its proven. How bad are the catalyst engines? What do you guys think.

Avoid any catylist engine simply because of the sensors that will get wet from the exaust mist and start sending codes.

Do the error codes it cause make the check engine light come on or does it cause the engine to run bad. Let me tell you the whole story and get your opinion if its worth it. I am getting the boat for seven thousand under value because the family just wants it sold. Original owner bought it and only put 28 hours on it before passing. The boat was paid off and moved to the family trust to be sold when I came across it. I would normally never consider a cat engine but with the boat being so cheap it has changed my mind. I just know nothing about them so I wanted to ask you guys. Does a boat this cheap with low hours make it worth a chance on a cat engine.

All boats built after Jan 1. 2010 with motors under 500hp will have cats

Like anything with more sensors there can be issues. The big issue is when something goes wrong the motor will need to be scanned for codes. The code scanner is a marine unique scanner and not the auto OBD scanner

Quite honestly I would pay a bit more NOT to have a boat with cats. In fresh water, its one thing. In salt water where exhaust replacement is a regular maintenance item, its a deal breaker. Price out the replacement of these exhaust systems and you will be stunned. While you can replace normal exhaust for about $700 in parts (good stuff not made in China stuff) figure like 3x the price for cat exhaust. NO THANK YOU, I can finally now justify the higher price of outboards, and get away from the I/O maintenance that can be such a pain here in the salt pond.....

Thank you guys for the advice. All things went South today. After driving 2 hours to the bank, I signed the papers and got the check and thinking I'm off to his guys house and taking home my first financed boat which I had worked for years to be in this position to buy a newer nice boat. I got to his house and he had all of the records for the last three years, all of the manuals, and even the original sales contract. Now, all of the maintenance records were from the dealer and for winterizing and simple items. I asked if it went to the dealer this year for winterization and he stated "No I did it, I looked on the internet and found how to do it". At this point, my stomach sank. I asked him how he did it and he said he sprayed fogging oil (CAT ENGINE) in the cylinders and poured antifreeze into the outdrive with the rabbit ears. Now, my stomach sank even further. I asked if he drained the engine and he looked at me with a funny look. I would say my stomach sank further, but I was already at rock bottom. I think you guys know where I'm going with this story. I pulled the plugs and unscrewed the blue handle and about 5 gallons came out of the engine with zero antifreeze. He started the engine and the engine and the temp would not move, of course, I pretty much already know why. Sure enough, the bilge kicked on pumping water overboard and when I looked at the engine bay water was leaking into it. As we were in the boat, water was leaking from the right side (port) under the exhaust riser. I could not tell where from but I am not aware of anything under there besides the block. This guy really did not seem to know what that meant and here I am left to tell this guy I think his block is cracked and the engine is shot. The owner felt really bad and apologized for my long drive and said he will take it right to the dealer to get fixed. I do not think he knows how much this will cost. Besides this issue of the engine, there is the fogging on a cat engine, and the owner went to start the boat with the outdrive in the trailer position, all the way up. I advised him that doing so will trash the u-joints and he said he did not know that and already started the boat in that position yesterday and let it run for about 30 seconds. The boat is gorgeous and in near mint condition; there is a small 2 inch scratch on the starboard side in the black paint. Everything on this boat is saying run, what do you guys think?

First your spot on with your assumptions.

He said he will take it to the dealer to get it fixed, I would wait and see what he says the dealer will do.

Cracked block... And possibly cracked manifolds, cracked cat manifolds? Sounds ugly.

That $200 in savings for not having the boat properly winterized is going to cost the guy $5,000-10,000. YIKES!

The seller is pretty made at himself. It is not a matter of money for him, but rather time I think. I talked to him and he dropped it off at the dealership and told them to fix it right. He knows it might be a new engine and is going to pay for it. Everyone involved hopes it is not the block but it sure does seem like it. If the work is done by a certified mercruiser mechanic and signed off on, what do you guys think? Original boat will have 28 hours than whatever the short block would have. I assume they would buy a new short block assuming they can still buy one. Does anyone know if there are still 4.3 shortblocks available?

They will probably do a 4.3 Merc reman, and if so it will come with a warranty. I wouldn't have an issue with

I would keep looking . . . a new (reman'd) engine is not a slam dunk and often are problematic if the dealer/installer did not do things right.

my bank said they normally need the title back within 24 hours to put the lein on it. they told me since i have a long relationship with them they will give me a week to figure it out. the bank suggested i talk to the dealership and see whats wrong then type something up that states he is going to fix it and have him sign it and get it notorized. the bank said if im good doing that than i can go ahead and give him the check if not i will have to bring it back to the bank to pay off the loan and start over when i find another boat.

Your asking for opinions, so mine is give the check back, and when the boat is done and ready (meaning you can ask what was done and if there is a warranty, and transferable) then go back and get another check. No need at being in a hurry
