Looking at some potential 47 foot motor yachts to buy in the USA and one has Cummins 6BTA5.9M2 300hp engines, another has the same basic engine but 6BT.5.9 at 210hp (turbo but no aftercooler). Are these good engines? I have heard the ones at over 300hp have raw water cooled aftercoolers that can be troublesome, but up to 300 have freshwater engine water cooled ones and are still fairly long lasting. Any comments? Engine hours on the 300hp ones are 1,950 and 2432 on the 210hp ones. The 210hp one is cruised at 8-9kts @ 3.5gph (US) max 15kts, 300hp one can apparently reach 18kts, slower speed is fine by me however.
Also looking at two others with Cat 3208TA 375hp engines which seem a popular USA choice, good or bad comments?
This is outside my comfort zone after 40 some years of rag and stik and max hp of 50!
