Engines - Sailboat inboards
This Scanmar link is an interesting story about an inboard engine
replacement. With the cost of inboards on sailboats it kind of makes me wonder what is the largest outboard put on the largest sailboat and how it was configured and located. I have seen a 25HP on a 30ft Grampian (transom mount) when the A4 gave=up. I wonder how an outboard could be used on a larger sailboat somewhere other than the Transom, possibly in a specially designed lazzerette... http://www.scanmar-yachts.com/docs/I...aintenance.pdf http://www.scanmar-yachts.com/NewEngineInstall.htm Rebuild or Replace; or, How To Throw Good Money After Bad http://www.scanmar-yachts.com/NewEngineInstall2.htm Installing the New Yanmar http://www.btri.com/boat/index.html "During the Fall of 2000 and Spring of 2001 I replaced my Farymann K30M with a Yanmar 1GM10.

Good work.
At this time I am sailing without an engine. I just took my 1 GM Yanmar (1982) out of the boat. This engine was properly maintained every year. It was rebuild last year by an experienced mechanic. This year, after about 50 hours of total running time, the engine stopped working. Now the engine is apart in three boxes. The crank shaft is broken in two. Now I have to make the decision to install a new engine or not. In Canada the basic cost of a 10 GM Yanmar is $6600.00 plus 15% HST = $7590.00 CDN plus installation. The other option would be to install an outboard engine on the transom. The last one is to sell the boat (a 27 feet Mirage 1982) without an engine and buy a pre - owned 30 feet sailboat.

Dennis, I am just starting to research electric motors (for
sailboats). What I have read sounds interesting. evparts.com is where I'm starting. I will possibly be replacing my A4 in time. On Tue, 06 Sep 2005 08:02:20 GMT, "Denis Marier" wrote: Good work.

My 28' S2 came with a Yanmar 1GM but it was an older one with only 6.5
hp output. Although it was the most reliable engine I had ever seen and ALWAYS started, I had been in a couple spots where I was concerned about not having enough power. I looked all over the internet for about a year and finally found a used Yanmar 2GM that was being sold. I took the chance that either it was in good shape or I could rebuild it and bought it and shipped it here. It was in Seattle and I am in Florida so shipping cost nearly $1000. One it was here, I started it and checked it out and it seemed in good shape. Rated at 13 hp with a heast exchanger for cooling it looked to be a good direct replacement for the 1GM after looking over the pyhiscal dimensions in the service manual. The boat was up on jack stands in my back yard with no way to get any sort of hoist around the boat to remove the old or put in a new engine. Nevertheless, I was amazed at how easy it was to remove the old engine. In no time at all, I had it sitting in the cabin looking surprised wondering how I managed to do it by myself. I enlisted two friends to get the old engine to the ground and the new one in the boat. We put a ladder against the boat and manhandled the old engine up into teh cockpit and up onto the cockpit sides. We tied a rope to it and slid it down against 2x4s placed against the ladder. The much heavier new engine was bolted to a piece of plywood and then using a rope around one of the winches we pulled it up into teh cockpit. From there we slid it on 2x4s into teh cabin. I then slid it back into the 1/4 berth and then down into place by myself. IT DIDNT FIT. The new engine mounts were too thick. The hardest part of the entire operation was for me to use my sabre saw to cut through the wood and glass engine mounts to make it fit. I went through 8 saw blades. It lined up very well although I did use a feeler guage. It started and ran well but soon stopped pumping raw water from a 5 gal bucket I had in the cabin. Finally, I traced the problem to a buildup of salt and corrosion in the output of the heat exchanger and fixed it. I am very happy with my new (old) engine and have extensively cruised with it. My boat now gets up to over 6 kts easily whereas before I was lucky to get over 5 kts. This has really improved my cruising ability because I can go for days running at 5 kts when ther is no wind. My experience seems to show that replacing an engine may be overrated in terms of difficulty and cost. BTW, I am no mechanic, just stubborn. |
I like your approach. However, Since I ended up with a broken crankshaft
on the 1 GM I am still apprehensive of buying used 2GM. You are saying that the shipping cost you nearly $1000.00 USD can you tell the cost of the engine. I starting to believe that (as you have stated) replacing a diesel engine is overrated in terms of difficulty and cost. The situation in this neck of the wood is that few people know about diesel engine. They seldom breakdown and when they do we have to call an experience mechanic. Here our diesel mechanics are very busy and do not come exactly after you call them. As in Seinfeld "the soup nazi" we here have the opposite for diesel engine repair. wrote in message oups.com...

I got the engine for $2000 "as is" and it turned out to be in good
shape although I expected it to be worse. When I sold the 1 GM, I really didnt know what it was worth and didnt want oto hassle with people getting it and then for one reason or another being unhappy so I advetised it on the internet for $450. My phone rang like crazy and a guy drove all the way from New Orleans (450 miles) to get it. Maybe I just got lucky. We also have no diesel repair places nearby so I expected to have to sorta "shade tree" it . Its only a diesel, not rocket science. (Gawd, how many times have I said stuff like that and been wrong) |
Thanks for the information.
I'll search the net for one used 2 GM. wrote in message oups.com... I got the engine for $2000 "as is" and it turned out to be in good shape although I expected it to be worse.

I believe both fresh and raw versions of both were built. Its true that most 1GM's are raw, but the 2GM has many of both types. The engine name has an "F" in it (as in 2GM20F) it is fresh water cooled, i.e. it has a heat exchanger. |
Very interesting links.
Answering your first question, but not really answering it because I'm sure your question is regarding monohulls, but the Gold Coast 65 ft catamarans had twin 50 hp or more on a sled between the hulls that could be raised. Catamarans can deal with the negatives of outboards--the esthetics and being able to locate them further forward. Nice to pull the prop etc. out of the water. But I recall a comment from someone that his, say 25 footer (mono), performed better under power with an outboard than a sister ship w/ inboard. Most likely the inboard was compromised w/ a small prop for less drag under sail. "Mic" wrote in message ... This Scanmar link is an interesting story about an inboard engine replacement.
