We repowered Aloha (hull 72) at a yard in St Augustine, FL in August 2015 with a Yanmar 4JH-80CR. The engine itself was a little over $16,000, and installation was about $4000. Frequently, the install can be as much as the engine, but that should not be the case on an SM due to ease of access. I’m not sure who is quoting you 55k for this job, but I would look elsewhere. Also, if you are considering going with more horsepower, I’d stick with the 80hp, as we have found it to be economical and plenty of power in all our cruising. At this point, we have 680 hours on the engine, and it has performed flawlessly. We consider it to be one of the best investments we have made in our boat. The engine came with Yanmar mounts, which we installed, but their was no mention from the Yanmar rep who inspected the install that we were required to use them. We ended up changing the mounts back to new original mounts in Martinique a little less than 2 years later. The French Yanmar/Amel mechanic inspected our alignment and found it good, but determined the Yanmar mounts were a bit to soft, and caused premature wear in the rubber bushings inside the Vetus coupling. Moral of the story is that I would not use the Yanmar mounts. We have had no problem with wear of the bushings since switching the mounts. Feel free to contact me if I can help with any other info. Regards, Steve Davis Aloha SM 72 Currently anchored at Lahaina, Maui
