Surfing Craigslist, I spot a tired looking old dinghy with a perfect wineglass transom. A few dollars later, she's strapped securely on top of the jeep, and we're on our way home. This is as simple and rewarding as a project gets. Let's see what we have for leftover parts & paint in the cabinets...

What is the significance of Yanmar using Kubota blocks? So what if they do. It does make a difference. The little Kubota based diesels are easy to find parts for. Lots of tractors and generators are also using the Kubota Z482. In fact, if things go really bad with your boat's engine, you can buy a ...

John, CD28

Also, after reading about some of the "drop in" factory engine configurations, I'd like to see where the mounts are going to end up when they're supplied for your "drop in" replacement and whether they block or interfere with anything/and how... PS: Not a recommendation, as I'm ...

John, CD28

Went to the Maine boatbuilders show yesterday and talked to Yanmar, Nanni, and Beta. Looked at the 14 hp models from all three. All based on the Kubota 2 cyl. Yanmar is using a Kubota block too? http://www.yachttantalus.us/Images/Repower/BetaVolvo.jpg I just swapped out a Volvo MD7A for a Beta 13.5...

I climbed in and put the meter on the shaft - it's not grounded. There is no continuity between the shaft and the boat's bonding system. The transmission, bronze stern tube, and rudder shaft are grounded. Even the stainless cap that covers the outer end of the cutless bearing is grounded (screws int...

don't take steps to mask the problem, Fix It. as Tim said something is up find the issues. check to see if there is a continuity between the shaft and eng. is the shaft saver allowing a connection. people use SS shafts and bronze props all the time with zincs that will last a season. (you should ch...

John, CD28

Thanks All, I'm not sure why the zincs are now eroding so quickly, but clearly something has changed. I'll start by running a wire across the drive saver, to bring the prop & shaft into the bonding system. I'll hang a big zinc grouper off the boat too, clipped to the backstay (bonded) to offer u...

John, CD28

John, Is your boat on a mooring, on a dock or in a marina? ...Is the stuffing box connected to the bonding system? is there underwater metal close to the prop / shaft that is bonded? What else is connected to the bonding system (house ground, green wire AC ground, etc)? In the photos on your websit...

John, CD28

I repowered the boat last year, and all goes well. Except for the zinc - that goes quickly. Very quickly. Before I repowered, the boat had a bronze prop (2 blade Michigan Sailer) on a bronze shaft, and a drive saver. There was nothing to bridge the drivesaver electrically, so I'm thinking the old pr...

John, CD28

Would a modern ablative paint avoid the build up problem on the prop? Perhaps it would wear off entirely, leaving the prop clean & bare mid season. Maybe you'd have a clean bare prop half way through the season. This would be better than half the garden mid way through. yes? no? (I dunno) John

John, CD28

Several folks (not here) have told me not to paint a bronze prop. I don't recall the reasoning but they were pretty sure the sky would fall if I did. It seems all the bronze props in the yard are bare while all the bronze thru-hulls are painted over. If we regularly paint bronze thru-hulls, then why...

...The 28 and the 27 are very similar boats, of course, but have sort of different characters. As they say, the 27 is the biggest of the small CDs and the 28 is the smallest of the big ones. The 28 is a bit roomier, especially since it doesn't have a lazarette... Sweet boat you've got there Duncan!...

Way down there? I always felt I was exploring the ICW as I went through the Cape Cod Canal.

I guess I'll have to venture further afield next time :)

Hey that looks neat! I've been playing with Google Earth, and adding pictures via Panoramio. I'm not sure if it's working though. Do you by any chance see my picture of a pilot whale in the Cape Cod Canal when you zoom in near the Sagamore bridge (east end)? Or does Panoramio only add the image to m...

Hey that SPOT report is really cool. Does that come with the basic subscription price ($100/year +/-)?

It's a slippery slope. One thing you find after a while is that it's just all too easy to overthink everything. Tim's right (again). On my boat I overthink everything. Invariably, when the job's done, I realize there was something I didn't think of. I happily cruised coast of Maine two summers in a...

I think you're right - it was Obi Wan.

Apologies to George Lucas!

John, CD28

As Yoda said, "USE THE FORCE, LUKE." That's how I set the rig the first few years; I had been using the "twang" method for the 4 summers I've had the boat in the water, and just went to the Loos gage this summer. The rig tension isn't that much different in the end, but I do like...

John, CD28

Something ain't stirring the kool-aid. With a masthead rig the length of forestay and backstay should affect rake, but not induce bend. How's the rake?...Bend has more to do with the lowers. Can you ease the aft lowers? Before I added the two toggles under the roller drum, If I slacked off the aft ...

Ok, I finally get around to the rig on my old boat. This is a 30 year old Cape Dory 28, masthead sloop with single spreaders. I buy a Loos PT-2, and Ivar Dedekam's book and have at it. It didn't take long to realize there's a banana in the mast, big one too. The mast was bending forward above the sp...

David - sweet boat you've got there ;) I planned a 2 week cruise, and was promptly shut down by weather. This was a scary looking cloud off Cape Ann, delivering a 50kt gust, rain, & hail.

I used Rule's Elastomeric Sealant to bed bronze thru-hulls on an old boat once. Just a few years ago, the current owner of that boat & I pulled them back out, and the elastomeric sealant looked fine.

Even if your theory pans out the water lift MUST still be locate LOWER than the exhaust injection elbow! Yes, this is mandatory. The muffler must be well below the elbow - always.

After drilling the vent hole, and letting the epoxy cure in the hole I had to drill in the lower half of the tube to allow the bit to reach the upper inside of the tube, I repeated the water volume test.

I'm really concerned about the 2" hose now. If I did the math correctly (pi x radius squared?), the 2" hose has 1.7x the volume of 1-1/2" hose. This means 1.7x the water volume will be sitting in the 2" hose between the muffler and the top of its rise after the muffler. These are...

I must admit that after reading of Tim's nightmare getting a prop shaft for his boat, I was a bit nervous. I gave Hamilton Marine a call, and described exactly what I wanted.

Ok, my muffler and hose arrived this week; I went with the Vetus LP, as it is narrow, and looks easy to fit into tight places.

Metal? Hardwood? Everybody uses that. Where's your sense of engineering adventure? I'm going with the Azek. Now, I just need to get some Gorilla Glue to hold them down.

John, CD28

Assuming this motor lasts 30 years like the old one did, there's a good chance there will be cooling problems along the way. I don't want to compound a cooling problem with a melted muffler too. Maybe Vernalift is the way to go.

Thanks Tim.
