If you have a true 87 140, then you have a small bore looper 90 degree V-4 and it will be one fuel effcient 2 stroke. I have an 85 that I modded to mostly an 86 and that thing sipped fuel on every boat I've had it on averaging a fuel burn around 6-7 GPH. And they are a STRONG 140HP that can hang with most 150's, and leave em at the fuel dock. The late 90's 225 is a great engine, but is one of the thirstiest 225's ever turned out by OMC with the small exhaust ports and finger ports for the intake to force enough air through em to make 225HP. If the 140 isn't rotted out, then that is still my personal choice over the 225 for a V-20 as they simply aren't heavy or big enough to really need the 225HP. And for the rare occurrence that you will be able to use it offshore I don't think the extra fuel burn will be justified. The 140 will burn about 1-1.5 GPH at an idle, the 225 will burn about 2GPH. At a 30MPH cruise I would expect the 140 to burn about 8GPH, the 225 will be closer to 10GPH.
