I would encourage you to re-think “ new engine
.” We recently had engine
issues that were significant enough to ponder a new engine. The quote for a new comparable engine was $17,000 not including the actual installation
and necessary alterations. The old engine -Westerbeke 55 - ( actually an Isuzu 4LE2) was rebuilt for less than $2800 drive-out. I didn’t use a yacht shop, I used a diesel
shop familiar with construction equipment Diesel
engines. Got it back in 9 days. Repainted it and replaced all belts and hoses myself (extra $400 ). No modifications to the mounts or engine compartment, shift linkage or fuel
, drive shaft or electrical
The engine vendors I talked to- a lot- were fairly consistent in telling me that engines at present are generally back-ordered, and not to expect availability before September.
The beauty of small marine
Diesel engines is that in almost all cases the engines were designed for general applications: pumps, compressors, generators, front-end loaders, fork-lifts, etc. etc. thus familiarity and expertise is not confined to the relatively small yacht industry. Parts
(Westerbeke) engines for example from the early 60’s are still commonly available. High-time diesels (15,000 hrs) abound, though at some point injectors will need servicing and poorly-attended oil
changes and other mal-maintenance issues will require bearings and rings.
But I’d update it, not change it.
