Yanmar or Westerbeke?

I was the proud owner of a YSM12, a one lung, raw water cooled beast that snapped engine mount studs as frequently as some people change their underwear. Finally had to install an AquaDrive system to isolate the engine from the boat hull and eliminate the snapping studs problem. Little did I realize until much later that Yanmar had withdrawn the YSM12 from the marine market and my builder had evidently picked up my engine at a close out sale. Had the boat 11 years, and that YSM12 was a PITA the entire time. Today's Yanmar product is a high RPM, low weight unit designed for the power boat market, not a low RPM, high torque unit designed for a sailboat application. Yanmar has figured out the the power boat market spends money and the sail boat market talks everything to death, but doesn't spend any money. Lew I have a friend with a YSM12 in his 27' sailboat. He installed it himself so maybe he does not have stock mounts. My old 1GM broke a mount but I never got around to fixing it for 9 yrs and never had another prob with it. That little engine sounded like the African Queen but in 9 yrs started EVERY time no matter what. It was also very easy to work on. I thought it was a great piece of engineering but at 6.5 hp, a little small for my 7700 lb S2. So, I found a use 2GM (13 hp) and I think it is also wonderful (installed it myself). I admit, this is only two data points. |

That little engine sounded like the African Queen but in 9 yrs started EVERY time no matter what. You betcha. Thought about Hepburn and Bogie everytime that little beast was at idle. Could point upstream and idle in place against about a 1-2 knot current at less than 1,000 engine RPM.. It was also very easy to work on. I thought it was a great piece of engineering but at 6.5 hp, a little small for my 7700 lb S2. Nice boat. So, I found a use 2GM (13 hp) and I think it is also wonderful (installed it myself). Different engine. The YSM8/12 were great inustrial engines, not so great as marine units. The points remains that today's Yanmar product line is a light weight, high RPM family much like the old VWs. Works well in a hight speed power boat, not so well in a sailboat which needs high torque, low RPM. Lew |

When I bought my S2 with the 1GM, i was worried about being able to power into thunderstorms (we have a lot of them here in N. FL) so I had the 2 blade prop replaced with a 3 blade and it seemed to work well. I once ran from Naples, FL to St. Marks FL no wind at all the entire time for 250 miles and burned only 12 gallons of fuel at 5 kts the whole time. That little engine never missed a beat. |

Yanmar or Westerbeke?

My yard is recommending another Westerbeke but all the sailors I talk to say Yanmar. My genset has a 35 hp Yanmar diesel that is still going strong after 2,000 hours in three years. It replaced a 10 year old Westerbeke that was getting flaky in a variety of ways. |

Your best bet seems to be... http://www.volvo.com/NR/rdonlyres/EE...C6-5100F8A3BEB... Volvo has a reputation for expensive parts, *but* their engines are now made by Perkins which has a long and proud tradition of rock solid diesel engines. Want proof? Note the displacement / bore / stroke of the Volvo in the above .pdf with the Perkins model 404D-15 he http://www.perkins.com/cda/layout?m=97265&x=7 So, if Volvo is simply 'marinizing' a Perkins, and if Perkins parts are widely available and resonably priced, why shy away? Too, the Volvo has a whopping 115 Amp alternator as standard equipment... which is a nice feature, but perhaps not one to base a decision on I believe Yanmar makes a fine product, and unlike all of the above, it's *their own* product, i.e. they aren't 'marinizing' someone else's block - it's a Yanmar from tip to tail. This might be considered a good thing by some, and a bad thing by others. My suggestion would be to print out the various spec sheets available from these manufacturers for the 40+/- hp engines, grab a highlighter and start making notes. With a few hours study, you'll be well on your way to making a informed decision, which will give you a leg up when it comes time to buy. Let us know what you decide, and - perhaps more importantly - why! MW Am not sure why Hodgett does not like Yanmar. I have had two and they are the most reliable machines I have ever seen.- Hide quoted text - - Show quoted text - Ditto my experience. Yanmar very reliable. I've had various 1, 2, and 3 cylinder Yanmars, all reliable. Very, very important to have good shaft alignment with any engine installation. Poor alignment is the usual cause of motor mount breakage, although some mounts aggravate the problem by sagging. Also very important: clean fuel and proper propellor match. With proper gearing and prop match, high rpm engines very OK for sailboats. The only real disadvantage is that hand starting can be next to impossible with the low flywheel mass, so be sure to maintain your starting system (battery, wiring, starter motor). Paul Mathews |
