The most honest engine raters are those that use their engines for commercial gensets, notably Cat and Cummins which are the most popular in the 100 to 200 HP range - operating at 1800 RPM.

The Cummins 6BT genset gives 24/7/365 numbers at 112 KW or 150 HP and Cat's C6 is rated at 138 KW or 185 HP. These two are 5.9 liter engines. One of the most popular gensets is the 7.2 liter Cat C7 rated at 150KW or 200 HP. All three can be purchased with a cradle to grave warranty if you adhere to the maintenance programs.

The Cummins 6B block in its marine propusion variant can be goosed up to 400 + HP and the C7s 450 HP so the genset versions are pretty well loafing. Alas the underachiving C6 has the same marine HP as genset HP for continuous duty at 1800 RPM. The Cat C6 (or Perkins Sabre 225 TA when rebadged and painted blue) sits in my vessel as the propulsion engines.
