Can anyone tell me if the Oday 25's ever came with factory diesels? Can you give me a bit of the history as to the brand and size of diesel? Are there any owner opinions? Don Evan's and any owner that has completed the task of installing a diesel, what was the deciding factor? Next question. Is there any differences in model years of the Oday 25 and what were they? They stopped production in 83, was this the best year? r.w.landau

25 O'Day Diesel
The 25' O'Day did come with an optional Diesel, but I don't know what years they were available. It was a single cylinder Yanmar. This particular engine was rather popular at one time on other boats but I am not sure it was very reliable. My only encounter was of that with a friend who had one but had a myriad of problems with it. Could have been a lemon or a poorly maintained unit. You won't find that particular option for the 25' O'Day very often. I've only seen one O'Day with that option for sale in the past five years. I am also aware of a Diesel plant set up much like the OMC SailDrive, but I don't think that was available on the O'Day's. I think it was Volvo that made it. RKM

Diesel Onboard
R.W., I believe you could always order a factory installed diesel on the 25. O'Day seemed to jump around with their suppliers. I've heard of at least 5. They were typically 1 cylinder, raw water cooled units, ranging in size from 8-10 hp. Raw water engines sailed in salt water are fraught with problems due to corrosion. There were some kits available to convert to closed cooling, but cost and space were always a problem aboard the 25. I do not know of any owners who have original diesels, these would be now over 20 years old. I know a few more who have added them later on, one owner adding one this past year. Typically, space is at a premium, having to give up locker and drawer space, which is already limited aboard our 25's to begin with. I modified my galley, turning the corner and adding a new set of drawers, and in the process loosing a bit of the starboard settee. Not a great loss in my opinion. The decision to add a diesel was easier to justify 14 years ago, then now. The boat was worth considerably more then, and costs were about half what they are today. It was a good decision then, but I could never justify it today. Three main reasons for installing one was dependability, a prop buried deep in the water, and a reliable charging system. I have probably dissuaded more owners from installing one than persuaded them, but only you can decide this for yourself. If you can get your hands on a good used diesel, and can install it yourself, it may be worth it. The cost of the engine represents about 60% of the initial outlay, people forget this part. Prop, shaft, cutlass, stuffing box's, flange, fuel tank, bed, hose etc. and installation make up the rest. Hope this has been helpful. Don It seems there was very little design changes from year to year on this model, unlike some other models. They seemed to have a successful design and perhaps did not see any advantage in screwing with it. Cabinetry about the galley seemed to be one area they altered slightly.

Thank you for your responses !
Thanks Russ, JT, and Don. I have seen the 25 with the Yanmar online. It is currently under contract. Your responses about the problems may be why the 83 boat was going for 7800.00. Thanks again r.w.landau

ODay Diesel
Dear Landau: Here in Brazil O´Days were manufactured till 1991 under license. My 25´came from factory (Marine Boats) with a Volvo 2002 with 18 hp, diesel. Under power I use to reach 6 knots cause the engine is very powerfull to the boat size. That´s it. Orival macieri@terra.com.br orivalmacieri@aol.com

Engine never removed or worked on.
