Have you looked at the FPT NEF 6.7L 450 hp engine? We have successfully replaced 6LY Yanmars in 4 Hinckley's now, 2 of which were twin engine and had very limited engine space. The FPT marine packaging and overall dimension is much more clean and compact than what you are comparing currently. We have also had no issue repowering a Hinckley 29' Runabout that was originally fit with a Volvo D6, we repowered also with the NEF 6.7L 570 hp engine. Just curious.Thanks for the input guys. I was attempting to see if there were any viable alternatives to the Yanmar if and when a replacement might be needed. Was also looking more a little more speed on this rig but the space is not only limited down below but at the prop too.
...My Cummins guy is on Vacay. Would anyone know if you can squeeze a QSB 425hp in the same space as a Yanmar 6ly-stp 370hp if not how about the older B series 370 Cummins ?
maybe i missed something, but what kind of boat is it? does it already have an engine box? maybe engine height isnt the issue, just width and length.
What happened to the Yanmar?[/QUOTE
The Yanmar in the boat (that I am looking to buy)is good. I am hoping to pick up a couple kts of cruise speed so I am planning ahead to see if this could be accomplished in the space provided. The Yanmar has a small footprint which you are aware of. The purpose of my inquiry is to find out if it is possible to achieve these expectations prior to purchasing. The boat is a 31 Willis Beal, and the good folks I have had contact with on this forum have indicated that my cruise would be roughly 15kts...I was also quoted 17 @ 80% load. I got the feeling 15 is what to expect. If I knew we could get 18-19 with this rig with a engine HP increase in space provided this deal will be done. The other issue is there may only be room for a 22" wheel....
Please don't refer to the NEF 6.7L 280, it is not an engine that is sold in the U.S. any longer. Please only refer to documentation up to date that is attached here.Try this again,
Here are the dimensions of the Yanmar 6LYA. Easy enough to measure up what will fit or not fit.

btw, the QSB 5.9 is offered as a Tier II RECON.....very very competitively priced.

All the FPT engines are posted on the MSHS website, but you have to know which engine family you are looking for before you get started. No, they are not identical, the mounting foot print is similar but not 100% the same and dimensions are different as the hardware is not the same due to torque output. The dimensions are attached to the same brochures as the performance graphs.My apologies, the spec sheet was posted on Hugo Stamp website..your FPT distributor.
I was looking for dimensions for this guy...not performance.
Is the 280 the same footprint as its big brother 570 ?
Yes ?? No ??
