Two cycle inboard question

[cheers]

I recently (may 2009) aquired a 1973 O'day Sailboat. I saved it from being crushed by a marina owner who had sold his marina. The new marina owners were taking possion and the boat had to go (it's a long story). Consequently, I have no documentation/information regarding this boat other than what in on the registration form, and what I can specifically find (not much) on-line. Someone mentioned it might be a special anniversary model due to the gold colored mast.
I have numerous questions regarding this boat, most of which relate to the fact I'm relatively new to sailing (two eventful seasons).
The most intreguing question I have relates to the engine. It's a 2 cylinder inboard, but looks just like an outboard that has been bolted to a plate in the hull. It's also a 2 cycle. I have not located any references to this type of engine being used in all my research. So I guess the question I have is...Can anyone tell me if this is the original configuration, or perhaps a modification? Any other related information would also be greatly appreciated.

Hello,

Can you provide any additional information on the engine? Make, model, pictures perhaps?

Also, what model boat do you have?

Good luck,
Barry

Thanks for the offer to help Barry.
I did realize that there were some ommisions on my post but rater than make the corrections I thought I'd check to see how well the post would work.
So...the boat is 27'. It model is "Bangor". The engine is a 30 HP "OMC". That's what I know so far.
FYI...I'm located on the other side of LI Sound in Branford CT.

OMC Saildrive

I think that you'll find that you have an OMC Saildrive. This is a 15 HP two cycle engine. There is a saildrive owners group in Yahoo groups that can give you a lot of information. Many parts are still available for these units. I've included a picture of my spare saildrive for your reference.

That sure does look like what I have aboard CHEERS. Thanks for taking the time to respond. Two things...I will try to find the saildrive group and, I will assume that the O'day I have was originally equiped with a saildrive.

Saildrive Links

Here are links to two websites for the OMC Salidrive:

Saildrive Owner's Group

groups.yahoo.com/group/saildriveowners/

A site that has all of the manuals and parts lists for saildrives

Steve,
thanks again for the help

2 cycle inboard...me again

Steve,
thanks again for the help

I just finished my visit to the OMC Saildrive site. According to the site,the Saildrive was first built in 1977. According to my registration, my boat was built in 1973. Any thoughts?

What's Your HIN

What's the HIN (hull identification number) on your boat. That should reveal the model year. If it really is a 1973 model and it does have an OMC Saildrive it would have to have been an aftermarket installation. More likely your boat is newer than the registration shows.

Steve,

Ok Steve,...thanks to you I'm beginng to get somewhere. Where is the # located on thr hull and what portion of the # would indicate (I understand how to read auto VIN'S) the yr. of manufacture?
Thanks...in advance...and...Cheers!

The hull id # is...xdym0046173. How do I interpret that? Thanks.

the hull id # is XDYM0046173...does that help?

ok...i visited several how to read hull id #'s web sites...no answers, just more questions. the hull id # is xdymoo46173 (that's more #'s than any of the how to read hull id's that i found). the "73" is of interest because the omc was not built until 1977. any thoughts?

In addition to my 2 cycle posted issues, I seem to be having trouble posting a reply as well! The hull id # is "xdym0046173". The "73" portion of the id # is of interst because that would incicate that the boat manufactured in 1973, however the omc saildrive was not manufactured until 1977. oh boy...

HIN Number

I think that your HIN should be 12 digits. You are only showing 11. The XDY is the O'Day designator. I believe that the M is the designator for the 27 footer and the 0043 is the hull number. The 173 probably means January, 1973, but there should be a 0 before the 1.

Regarding the fact that the boat was built before SailDrives came out, one of the websites that I gave earlier has an installation manual for the after market retrofitting of a SailDrive to an existing hull. Although it looks like a very hard thing to do this may explain your situation.

Let us know if you can find the 12th digit in your HIN.

Thanks again for your efforts. I double checked, and that is the # that appears on the registration. As I think more about it, it also appears to me that the boat was originally designed with an inboard engine compartment. I'll keep diggin'. It's cold and really windy up here. As I check how the boat survived the day, I'll check for the HIN. Thanks, Mike

It's still cold and windy, the boat survived the estimated 50+mph winds, but i could not find the hull's ID #. Where might that be?

The HIN will be located on the outside of the transom, it SHOULD be in the upper corner, near the starboard side. However, mant sailboat builders placed it dead-center on the transom or nearly so (location on my DS II).

I think many of the O'DAY 27s were sold with outboard power (That was the standard from 1973-78, the entire production run), some had a factory optional 25hp ATOMIC-4 gas inboard, others (especially early ones) had a 7hp VIRE 2-stroke inboard with a regular shaft and prop. Later model years an optional Diesel may have been installed at the factory. Basically, all 27s would have had the engine compartment I suspect, outboard models would use the area for stowage. Quite a few of those outboard models were owner-upgraded to inboard power, many installed a diesel, but the OMC Zephyr like you have was less expensive and should actually be a LOT easier to install than a standard inboard with shaft, strut, and prop. I suspect many Zephyrs were owner-installed if the owner was handy with fiberglassing.

Thanks for responding. The information you provided was interesting and based on everything I've discovered so far, seems to be a very reasonable explaination for my boats configuration/situation. I'm also interested in knowing where/how you got all this information.

The Zephyr OMC saildrive engine was not built till 1977. If your boat is, in fact a 1973 hull then this is an after market add. The engine is an OMC/Johnson/Evinrude 30 HP powerhead detuned to 15 HP. There is an absolute wealth of information on the Saildrive owners web site at Yahoo. Also the link to the fellow with manuals is a good one and you WILL need the manual to use this engine and maintain it. It's a dependable and somewhat hinky engine. Get thee to the saildrive web site and go from there. Good luck.
