- In this video I finally get to taking a look at the diesel engine that came with the boat. It was sunk with the boat in salt water. I have never worked on a diesel engine before, so I'm learning as I'm going. The engine is a Yanmar YSM12.
Good choice on the outboard. All the best working on your project.
We'll see how it goes. I'm still torn about how it will look on a sailboat. If you're out here in the summer look us up. We're usually around. Thanks Robert.
Hi, I too have a ysm12 on my 28' Albin Cumulus. It's still ticking good, for now, but needs new mounts ($500), some rust eating away at the oil lubrication tube ($200) return fuel tube (no longer stocked - fab only). Replaced the cracked exhaust elbow and water pump 4 years ago when I bought the boat ($800 right there). Yes an outboard is a cheaper option, if you don't like it you can always remove the bracket and go back to inboard, but definitely get the extra long shaft (25") and a solid wide plate to spread the load on the stern. 9.9hp definitely enough, my previous C&C 27' had a 9.9hp yamaha, never used more than 50% throttle to reach haul speed... but I hated it, the prop kept coming out of the water (extra long shaft would've helped), noisy, and with a transom hung rudder the outboard messed with the balance of the boat. Anyhow, I've decide for my use case I'm going electric, I do mostly day sailing and for short coastal cruising I can bring my portable generator along. Near zero maintenance, reliable and no winterization, lifepo4 batteries getting cheaper by the day so I can always get more capacity later and the beauty of near silent power sailing and no diesel fumes make up for the electric shortcoming of not being able to motor full throttle for hours but hey it's a sailboat. Still more $'s than the outboard solution but our older boats with dead or dying diesels are the perfect use case for electric.
Thanks for this detailed comment. You make some very good points. The type of sailing you do is pretty much what I do also (although I dream about crossing oceans lol). I'd say it will be next year before I'm ready to power my B29, so maybe electric will be even cheaper by then. Thanks for commenting. Much appreciated.
hey Bill, If you decide on an outboard (long shaft) between 10 and 15 hp, you might want to consider hanging it on an inboard transom so that the prop hangs just abaft the rudder and would still be more or less out of sight. This would be similar to what the smaller Albergs (another famous and popular 'classic' sailboat from the 70's and 80's) design use and very successfully as well - check it out.
I have an Alberg 22 (so far without a motor and it's also my 'project' boat) and some day when I get bored (ha ha) with sailing my Bayfield 25, I'll get to it. I also believe the larger Albergs use this power design and if and when my Yanmar YSE 8 gives up, that will be my method of dealing with it. I hope this is helpful.
Meanwhile you have an otherwise beautiful vessel in your Bayfield 29 - great interior layout, stern davits, wheel steering, cutter rig ...WOW!!! It's worth every effort!!!😀
Alberg 22 is a great boat. Im not sure if I can build a well to put the outboard in, but I do like that idea. I've seen videos of that concept on bigger Albergs like you mentioned. However, since this last video, I've kinda decided to keep trying to clean up the Yammer. It took a couple of weeks, but I finally got the piston out and am currently trying to get the rings out and the head cleaned (It was just sitting there so no harm in trying). We'll see how it goes by launch time. If the Yammer still isn't working I can always fix a motor to the back to use in the meantime. If I can get it working, that would be a huge bonus. Thanks very much for your comments. They're always appreciated.
I'm really inspired by your tenacity and it gives me great hope if or when the day comes when my YSE8 decides to pack it in. Never give up and all the very best to you (and Gerald - both of you) made of the same really good stuff!
fine mooring block I figure haha. You'd likely end up needing another head, and depending on the condition of the cylinder walls, it could need new cylinder/piston too.
It would... And it is used to being in the salt water... lol. I'll hang onto it for a while. Maybe I'll give it another try to fix at some point. Thanks
I don't know about Bayfields, but I read somewhere that sailboats that were designed with inboard engines have a weaker stern not made to sustain the pressure of an outboard motor.
I think if the engine is too heavy that could be the case. I guess a good backing plate or large washers on the inside sound help keep the mount attached. I'm not talking about anything more than 100lbs or there about. Thanks for the thought to consider. Much appreciated.
Bill, a four stroke electric start 15 horse outboard in my opinion.
Agreed. Yamaha has a nice one that I checked out a while back. It's better to have too much power than not enough, especially when you need it. After reading some of the comments below I'm now back on the fence again between fixing the diesel and outboard lol. If I do go with an outboard, 15 Yamaha is the way to go. Thanks
There are lots of old yanmar owners out there that would want your engine for parts. Put it up for sale
I appreciate that, but I think Id rather hold on to it as a longer term project to fix up maybe. Even though I like the outboard idea in every way, except for the asthetics, deep inside I'm not ready to let the diesel go just yet. Thanks
i would nt right off your engine just yet ,the head looks good ,engine machine shop would have two new valves ,seats and guides and looking new for not much money ,price up new gasket set and piston rings you may be surprised ,as for freeing off and removing piston easy AF, boil up some engine oil on a gas stove turn engine on it side and pour the boiling oil over ontop of piston let it sit for an hour then use a block of wood on piston hammer it lightly and then crank over engine ,just investigate more on your parts prices and whats available injector could be removed same time at engine shop and easy to recondition new tip inner spring seals
I will check out a machine shop for the head work and also try the to move the piston again like you said. I probably won't get it all done before this sailing season, so might have to go with an outboard for this year. No harm in trying some more I guess. I like everything about an outboard except the look of it on a sailboat. Thanks so much for the good suggestions.
If the engine has spent days submerged in salt water...every part needs to be disassembled and inspected and a rebuild beyond what is economical. Find a used engine? If you go the outbord route, think about stormy weather being driven onto a lee shore in waves, you need the engine to make sea room to survive, in the pitching waves the outboard just does not work. But then I was thinking out of the box, maybe reinstall the drive shaft and prop, then just through a Harbor freight 15 horse off the shelf ($600.00)to drive that prop forward when you need this emergency drive, use the old yammer transmission as a coupler. Then do your cheaper outboard as your normal sailing. When I watch the "Red Green Show" comes to mind at times, in a good way.
I would suggest that you look within UA-cam for a British channel "REFIT and SAIL" this will lead you to a professional restoration of a 32 foot Contessa. It is quite educational and step by step through the various problems ahead and behind. Remember cost are cubic in boats, cube 29 then divide by the cube of 25 and you will find that restoration cost are going to be at least 160% more for the larger boat. ((29 x29 x29 x29)/( 25 x 25 x25))= 1.60 All the best wishes and Spring is just around the Corner , what a long corner though.
Thank you for the comment. Reverse is rarely used anyway so your point about the cheaper engine is a good one for sure. I agree that rebuilding the YSM12 is not worth the cost. Also, It's going to take longer than one year to get this boat in the water, which was my original plan. This year I plan to enjoy my B23/25 and keep eye open for the parts that I need to refurbish the 29 - like an engine Ana few other things - over the next year or so. Much appreciated.
Remember the old transmission and bell housing on the motor will make a modified motor switch possible, do not through it out until you decided how to power. And you would have a reverse. ( I am looking at Bayfield 25 in my area, that's how I found your channel.) @@newfoundsailing
@@brianferguson6278 Yes I'll hang onto it all for sure. B25 is a great boat. The earlier model (23/25 is the one I have. It has a 2 stroke gas engine in it. The later models have the 8hp diesel. You can't go wrong. All the best with it.
Noooo......not an outboard.
Soak the cylinder in transmission fluid. An outboard would look horrible on a classic boat like a Bayfield.
Trust me I hear ya. I might have to go with an outboard for this season and keep the motor as a longer term project. Thanks.
