Default 31 Jupiter Sea Trial, Lesson Learned, Stuart FL

Had an interesting sea trial yesterday. A reminder of Caveat Emptor. From the Greek, the buyer is responsible. Enter one very nice looking Navy Blue / White 2005/6 Jupiter 31, twin 250 4S Yamahas with ~1700HRS. Boat is represented as near perfect and it looks the part. After tough negotiations, a 10K deposit and a few failures to produce by the broker we are off on a sea trial. The broker reports the boat to be full of fuel, just in case we head to the fuel dock to top her off. $387 worth of fuel later all three tanks are full. The boat looks, starts and runs great. We head out the Stuart Inlet at 5900 RPMS, the engines are just singing. Then, light grayish smoke begins to appear in the exhaust trail. We slow down and everything seems normal. The engines sound great, no alarms. Off we go and no smoke. Thinking the smoke is just carbon burning off. Run the boat for about 30 more minutes with an increasing smell of fuel. On the way in we ask the mechanic and hired captian to run it up again. After a short run the hint of smoke comes back. The engines continue to run flawlessly through the rest of the trip. After hauling out the mechanical inspection begins. First engine has 175PSI every cylinder, a bit high but, possibly due to heat. Every plug looks pretty good. Engine two begins the same way until a lower cylinder reads 220PSI and the plug is black, oil soaked and gummy. Two more cylinders have the same result. This is not good. Next we read the engine hours.Both engs ~1000 under 1K RPM and very few ~20 over 5K RPM. #2 engine is dead. Engine number 1 is probably about to meet the same fate. My guess is failure to run them up hard for a few minutes every trip and no ring free. Returning to the console the smell of fuel is now overpowering. There is a leak somewhere. Interesting to note the deck plugs over the sending units appear freshly caulked. All in all the lesson is this. Based on how this boat looked and ran it was a buy. The deeper dig shows it needs a repower and tanks, potentially $60K bucks. In this high priced and ruthless market Caveat Emptor.

The initial post was not to indicate anyone was dishonest. Not doing their job, or taking too much on input from the seller, maybe. The tanks were much lower than reported, so filling them up is the lesson. Everyones view of full is slightly different. Mine is they are full to capacity. Anything less and leaks can hide. In this case the smell of fuel became very strong after filling them up. Confirmed by a top notch surveyor, myself and others on the boat. It could be as simple as a loose clamp or as bad as new tanks. Access is severly limited and it could turn into a real boondogle. The recently caulked sending unit covers is concerning. The engines ran great but, tested poorly. Based on the condition of the plugs and 220 PSI in some cylinders I suspect carbon build up and possibly damaged oil control rings. How it really happened is speculation. The condition is not. The lesson hear is just becuase they run great they may not be great. In my 40 years of owning and building engines I suspect the engine with high compression is toast. The certified Yamaha mechanic agreed. A rebuild would certainly tell the whole story. The other engine may not be far behind. My opinion, your welcome to your own. The broker never produced records for service which he promised to provide on several occasions. This is not material but, added to the other issues is reason for concern. If you say it, do it. This lapse may really be on the seller but, the broker is the one who promised to produce and did not. The sole and entire reason for the post is Caveat Emptor. Buyer be aware. In other words, from Mr. Ronald Regan, Trust but verify.

We attempted to do so with no success. Maybe reality will set in. I just hope no one else gets burned. This could turn into an expensive lesson for someone.

Default Showed very well

I looked at this boat with my son, boat showed very well, engines had high hours and price kept dropping 3k every 2 weeks, i knew she needed a repower, but at 100k and 60k for new engines still kit a bad deal. I would have gotten a Servey and hopefully found the tank leaks, Jupiter's and Contenders usually need new tank at the 15 year mark. Thanks for sharing i waz wondering why she was back on the market at same price.

The broker now knowing this will need to let potential buyers know about the issues or could be held liable!!

Pretty simple. You found a very good boat with engines close to parts value.figure to add new power. And what ever else needs replacement and make an offer. You will get a basically new boat at a significant discount to new.
Well made hulls like this basically last a lifetime short of a direct exocet missile strike.

I agree with the value of these hulls and long term reliability. It would be sold for a fair price. However, the broker feels splitting the $5K cost of rebuilding one engine will cover it. The reality is this boat will most likiely show up with a rebuilt or different used F250 and a $109K price tag. It should have a full tank of fuel!

Are you saying he thought dropping the price by $2500 was a fair deal? If there's something marjor and definitely wrong such as an engine about to go pop, to me that's all down to the seller. Something like say a faded hull, where you can see what you're getting from the outset and doesn't materially affect the performance of the boat is something you might consider negotiating on the basis of a price reduction but not by the full cost of putting it right.

Yep, that is his position. For 109 this boat should have two good engines and tanks. No worries, $750 bucks for fuel and testing is a small price to pay for the heartache this boat may bring to someone.

Smart call to top off the tanks. Appreciate the psa! A couple months ago there was an ocean master 31 in stuart with twin zuks. The fuel tanks and deck had been replaced. Well it had no inspection plates to access the fuel senders and the deck was separating from the gunnels in various places. He said oceanmaster did he job. So, Ok I drive up checked it out. Didn't add up. The job looked like crap in person. I called oceanmaster they said yup they sold him the tanks but he outsourced the install and deck. I asked the seller and he said he had no receipts and oh I forgot ocean master didn't do it. Yuuuhh huh. Boat seemed a steal at the then 45 ask. Liars out there man. 2 weeks later a buddy sends me a text with the same boat for sale again. New seller socks someone believed him. Except now it said it needed 2 new tanks and price was 15k less.

i would send the seller and broker the survey report

in some states they could be legally liable if they do not disclose but they need to be informed in writing of the issue / receive the survey report

that is why when you buy a house, some seller's brokers don't want to receive the inspection report nor have it sent to their client

i'd also consider posting up the boat details including name, location, make model year, make model year of engines, HIN and serial #s

You might save someone!

I drove 6 hours to buy a boat a couple years ago. The inspection went so-so (boat not as described and pictures omitted problems) - then I fired it up and the outboard ran fine at idle but immediately sputtered and shook at anything other than idle. The broker actually said to me - no joke - that the motor is still under warranty so I could get it "fixed for free." Holy moly. I kept hearing that over and over on my 6 hour drive home.

"31' Jupiter 2005
Please note.
Due to recent survey results showing high numbers on cylinders on the starboard engine we are running the engines with Yamaha Ring Free to see if it clears up.
Until we investigate we are not considering offers or scheduling showings.
As soon as we know more we will report results.
The fuel tanks are indeed full.
No smell nor change in full level detected to date.
Thank you for your patience.
We will report back on our findings.
No she is not a new boat but if you want a Jupiter she is a great hull."

what they have listed on their site...
