Hello,

We are relatively new to sailing and absolutely new to cruising besides weekend day cruises with J22 at the Boston harbor.

We recently purchased an ODay 28 with an Atomic 2 engine as our first and entry sailboat. Part of the "package" is a multi day cruise from upstate New York (Hudson) to Quincy Massachusetts.

We prepared in advanced for the actual trip, assuming not to sail more than 3-4 hours a day, harbor the boat in a. Marina every night, just take it slow and learn as much as we can by doing.

Now, the third day at the pickup location, we are facing engine problems. The previous owner put a temperature gage into the oil pressure plug on the engine block with is now leaking. For 2 days, semi professional people trying to fix the problems including a dysfunctional temp gage. There has been some oil at the engine bilge and on the block.

While the boat was advertised as recently refurbished engine, we are now questioning the conditions. We were prepared to face logistical and wheatear related issues but are now at the point where we rethink the entire ordeal.

The biggest question for us is rather or not the engine will hold. It's a 2 stroke diesel and we expect to motorized a lot since we are going to New York format least 2'days while only moving 5 knots. As the skipper, I'm technically inclined but have a tuff time judging cover rather or not the engine will hold. The overall condition of the boat considering the age is good but it has been an land for 6 years and only back in the water for 1 year.

Any advice is really much appreciated. We are Germans and you can be very upfront.

Thank you,
Joerg

If you can not find anyone to put a new oil gauge fitting on any engine I think you are in trouble!
You did not say the year of your O28. The engine is most likely a universal diesel 5411 or 5416 engine but actually made by kubota. 2 stroke.. do you mean 2 cylinder?

you need a oil pressure switch. which should be an auto store item. the light blue wire would be from the oil light switch on the engine panel. I beleive the fittings are pipe fittings 1/4 or 1/8 inch pipe.



D&R Marine is in New England Rudy is the sole source for anything Oday!

Denise,

Thank you. The Oday is a 1983. And thanks for the schematic. I did download the same last night when trying to understand the pressure gage function and rarer it had an electronic purpose. I guess not...:)

Our concern is more about the longevity of the atomic 2 cylinder under load. We will be cruising under motor a lot and not sure if overheating or any other temp/pressure stress related incidents could happen.

Thank you,
Joerg

Most diesels are pretty hardy creatures. If it has lubrication, air, fuel and cooling water, it should run fine. Leaking oil is not a problem as long as you carry plenty of oil to keep her topped up. Cooling water comes out of the exhaust pipe; look at it often and if it has plenty of water coming out, you should be ok. Check the fresh water level if it is a heat exchanger engine and if that level remains constant, that's ok, too. In an emergency, you can always cool the engine with salt water, temporarily. Carry extra fuel filters and change them as needed, but for sure if it has not been done since you bought the boat. If you are uncertain about the oil level or water level, stop the engine periodically and check them. Carry a spare battery (completely charged) that you can use with jumper cables, should you need.
Make sure you have a decent anchor and plenty of rode, ready to deploy if the engine stops. Have your sail covers off so you can hoist your sails quickly should you need, after all it is a sailboat first.
Good luck.

is this the boat? Looks like you got a pretty good deal.



Well.. it is a sailboat. and hopefully you will one day know that is the primary mode of power on a sailboat.

If you could take lots of photos of your engine and "more" we can offer more help.

you don't "need" an oil pressure gauge but it's handy. there's a mechanical one on my boat. the pressure connection is on a small pipe that is connected to a small hose that is in the engine block were the oil switch would have been. (port side rear of engine.

Is your engine raw water cooled or does it have a Heat exchanger?

As an update of a day full of adventure here is where we stand:

1) Oil pressure senor or plug was changed using a GM version / brand. There is only a lamp indicating the electrical connection on the control panel but hard to tell if it has been working.

2) Plug for temperature gage was changed but we don't have a reading on the gage.

We decided to take the boat and continue down the Hudson to Liberty Landing Marina closing watching the engine and use as much sail and current power we can get. We purchase two new battery today and will install them tomorrow. For the amount of 3-4 knots motoring, we are hoping to install a bimini as well.

Thanks for all your advice. We really like the Oday style and feel we have a good starter boat. We have also started (partial in German) a block if someone is interested.

Sunny regards,

Joerg

Hi Jörg,

As Capta pointed out, most diesel engines last longer than their owners patience. You will learn more as you go.
Dielse engines on sail boats are seldom worn out due to excessive use, rather the other way around - too little use is dangerous. Rust is another threat.

A leaking plug is not good, as it leads to oil in the boat which smells bad - I have never liked that smell. This is the worst of that part; as Capta said, just fill up more oil when needed.
But I think you should fix this, as it is not difficult. If the threads fit as they should, then it is just a matter of getting something to stop the oil sipping out. There are different posssibilities, either something solid or some liquid which hardens. Guess the temp in this area never exceeds 100 centigrade. (It is unusual that threading only is leakproof. The threads are used to get a mechanical hold, to get it leakproof something else has to be used. One example: To make the diesel fuel pipes connection to the cylinders tight often Cu metal rings are used, as Cu is rather soft. ).
In worst case, ask a [professionsal] mechanic.

From the information given so far it is not possible to say if the engine will last or not. Age? Condition? Use? Even with that info, it's difficult, inspection is necessary.
The other way to look on this is statistical. How many engines of this size and age are still used in sail boats? That would give a some kind of probability for your engine.

The issues you describe don't sound major. You can get by without all the gauges working for the trip as long as you monitor the engine carefully. Fix things properly once you get it home.

Member of our club has an ODay 28. I has a Universal M12 which is a 2-cylinder 4-stroke diesel. Actually a bit smaller than the 5411, but its fresh water cooled. Chances are if your engine has a heat exchanger its the M12.
