i seen this add on craiglist about this boat for sale.. boat looks nice. i want to buy it. but something is wrong with the engine.. here is the email..

what will cause an engine to go from Cruise to 0..


--------------------------------------

Basics:

1988 Bayliner Cierra 2655 on custom made trailer.

Sleeps 6 (well 4 comfortably)

Alcohol Stove

OMC 460 King Cobra engine

110 Gallons of fuel

10.5? Zodiac included

Not running. Gonna be some work involved.


More details:

Boat has been stored for 9 years and is in need of some cosmetic as well as mechanical help. Last time it was out the RPMs slowly dropped from cruise to 0. The engine never seized but for your sake you should assume it needs to be replaced.

The Boat is 30? LOA but is a 2655 model. In 1988 the swim step and pulpit were an option and not considered in the length. Weight is about 10K lbs so you will need to have a good size tow vehicle or rent a truck.

The Zodiac holds air very well. It does however need some of the seems to be re-glued. There is no outboard with the Zodiac.

The trailer it is sitting on was custom made for a boat of this size. Someone may just want the trailer to stop paying dock fees! Replacement cost of the trailer is about 5K. The trailer has less than 2000 miles on it. It has a brake flush kit. The carpet on the runner needs replacing and I would not try and move it with out greasing the bearings.

With some work it could be ready for the next boating season! Make me an offer?~!!!!!

"OMC Cobra" so right there it's a pass. Now, since they've said it needs a new motor just assume so and go from there.

No matter what you do, get a survey done. It'll save you lots of headaches.

Well.......the OMC 460 would have me running and screaming!
Who knows what is wrong with it.
Sounds like a huge money pit in my opinion.

RUN. You need new drive and new engine. 460's are no longer supporded with parts like couplers and exhaust systems. There are ways to work around using GM exhaust and maybe makeing a coupler from a GM coupler, but it hasn't happened so far.
OMC has been out of buisness for over 10 years. So you need a complete repower.
Aside from that, check the transom and stiingers for rot. After setting for 9 years, you better get it for close to free.

They are listing 110 gallons of 9 year old fuel as a plus somehow, that is kind of funny. I guess you know how much you will have to pump out and get rid of!

PS: You can't even get gears for the outdrive with a 460. They just aren't around anymore.

LOL, Sideways at best, not up by any stretch of the imagination.

Re: Want to buy this new Boat BUT something is wrong with the ENGINE

i thinking of something like this!!!

Buy a New engine with Sterndrive
Install Engine and Sterndrive


Sound like a good idea to me???

A Merc Bravo setup can go in there, someone here has done it and has lots of details. Start a new thread titled "Swapping out King Cobra with a Merc Bravo" and see if HTB shows up, he has done this.

Everything you said in the reply above tells me you have no clue what you are doing, but like the looks of the boat and that you are about to get yourself into an expnsive problem you can't get out of.

Re: Want to buy this new Boat BUT something is wrong with the ENGINE

actually Don. iam a very fast. learner.. i have read, listen to all what you guys have posted here on the forum. and Special thanks to my Boat manual books and my PDF files..

i have learn how Clutch work. worm gear. and how important is little thing. just like having to put gasket on a clutch housing. putting gasket on tilt motor. and nylon washer. everthing is important. LOL

i have remove intake manifold. wire brush the whole unit. remove exhause manifold, replace riser. .

install water pump on the engine. easy.. and my first project that started all this.. I HAVE replace the sterndrive water PUMP and 3 easy steps....

i have learn many tools that i could use later on the future. what happen if i get stock on the water.. now i have an idea of what happen..

How i learn all this??? because iam very cheap and i want todo the work. so next time i know how to repair it my self and not pay for mechanics.

Specially when iam on the water with my kids and family. . . if something happen. i will be able to fix it. and get my family home..

LOL thats a long one..

but yee..

Ayuh,... Then you should know by now that the Golden Rule is Never buy a boat that says OMC on it Anywhere....

Btw,.... Everything you've learned about fixing Stringer drives will be Useless as soon as you sell that barge....

I merged this with your other post. It has EVERYTHING to do with the boat you are looking at.

Re: Want to buy this new Boat BUT something is wrong with the ENGINE

ok I just did the swap from a 454 omc king cobra to a 350 merc swap. If you can find a donor boat and do it then you are looking at about a month ( best case) and quite a few collards but it is possible. I just finished mine. She runs awesome now. But, man /... I would walk away. unless you love the boat and have 1-2k above the donor boat price.
