1977 ODAY Repowering options Questions
 
Hello, Fellow sea lovers. I have recently purchased a 27 Oday 1977. it is in pretty good shape for a boat of its age and as all boats needs work. its pretty much bare as far as electronics and the inboard was removed at some point, which is why i was able to buy it for cheap. it sails great and i take it out often loads of fun.. my question is what small diesel engine should i be looking for to repower this boat? and how much horse power would be best.
I think the orignal motor these had were the Vire 7 engine. also where would be a good place to look for engines? the good news is the fuel thank is there all cables, wiring, thru hull shaft, prop and something which looks to me as an muffler of some short is all there. (looks like a black can) so any help with this would be great. also another question related to rigging. the standing rigging going to the mast it feels a bit lose is there a specification as to how much play they should have?
ok thanks in advance for the help.

Fair wind and following seas.

A quick look on Yachtworld showed ODay 27s with an Atomic 4, a small Yanmar diesel, and an outboard. A new diesel is going to run you more than what you probably paid for the boat. Even a rebuilt A4 is going to run several thousand dollars. A conversion from gas to diesel (or vice versa) is going to be a lot of work. Easiest and least expensive would be to go outboard.

I have an outboard and it works great a 9.9 2 stroke Marnier. My concern is for longer trips. I live in southern California and we have the channel islands nearest ones abiut 20 to 30 miles off the coast on these trips id like the added security of an inboard. I dont mind paying a couple grand for a nice used diesel. I can also install it myself saving me some money.. ive been looking on ebay and craigslist and ive found a few decent engine for 1500 to 3000 dollars. I just dont want to be stranded out there because my outboard died.. i guess thats a question though is this boat worth repowering?

The boat is worth it to you. like a car, don't expect a return on your "investment" make nice make it what you want it to be.
but as we say around here :)

Doesn't Beta Marine have a drop in replacement for the Atomic (BOMB) 4?

Thats what I would do:

Atomic Four Replacement - Beta Marine diesel engine using high performance Kubota diesel, Atomic Four, atomic 4, repowering

But again as others have discussed, you'll never get the value out of the installation. If this is a particularly nice, clean bristol O'day, then do it if you plan on keeping the boat forever.

I, on the other hand, would put up the boat on Craigslist with your current outboard and then scour for a different boat...one that had been repowered already but the owner needs to sell. You'd be amazed at how frequently a boat like that comes up for sale. In the end, you'd let the seller eat the hit of depreciation for a repower.

We repowered with a Beta. Good support from the dealer, easy (for our marina) to install, and love the color.

The diesels today are more efficient and can do more with less HP.

well i do really love the boat its my first boat. and the first time i have ever sailed was on this boat.. you think if i just got a bigger more reliable outboard id be ok? also are there any solar powered engines that are popular out there.. i was thinking as a possiblilty to instead of putting in an imboard just rig some batteries down there... i think the wieght of that engine couldnt of been more then a coulpe hundred lbs.. is that throwing my boat off though?
not having that wieght down there? any suggestions on my rigging would be great just like specs as to how tight they should be..

No pure electrical motor powered by solar panels and batteries has proven itself over the long term. Especially if you need to do more than just maneuver to your slip and/or get out to the sailing grounds from a marina. Pound for pound, there is no better storage for energy than hydrocarbons right now.

I have seen diesel-electric hybrid setups...but even Lagoon pulled their model that had that setup after a few years. I think Hunter had a hybrid setup. But both still have a diesel engine to power up and top off the battery's.

Batteries just aren't there yet to replace hydrocarbons for trusted, long distance cruising.

If you can find a good used diesel and can do the work yourself, that would be a good option. Probably in the same $ ballpark as a new outboard. Outboards have their advantages and disadvantages. They can be just as reliable as inboards, and have the advantage they can easily be removed for repairs and are much easier to replace. Main disadvantage is they don't power the boat as well as an inboard, especially in waves when the boat is pitching and the prop is coming out of the water.

I have a Yamaha 8 hp out board. It is satisfactory and will push the 29 footer against about 25 knot winds (barely). To keep the prop in the water is the biggest trouble with this setup.
