While only one of these test numbers was a Triumph 210/215. The others are of comparable boats. These are numbers from boat tests found on the web.

Suzuki DF 140, 127.4 cu. inches. 420 pounds. Estimated WOT 37mph, cruising 14.3mph @3500rpm, 4.5gph (20'6" Triumph 210 center console, 2100 pounds)

Suzuki DF 150, 174.9 cu. inches, 465 pounds. Estimated WOT 43mph, cruising 22mph @ 3500rpm, 4.9gph (22'6" Landeau Excaliber 2250, 1600 pounds NOT A deep vee hull, pontoon hull, performace boosted slightly to offset poor hull configuration)

Suzuki DF 175, 174.9 cu. inches, 465 pounds, Estimated WOT 51mph, cruising 25mph @ 3500rpm, 4.9gph. (22'6" SeaFox 225 BF Bay Fisher, 2,350 pounds)

From looking at the above it seems that the 175 is the most economical of the engines at 5.1mpg, the 150 next at 4.5mpg and the 140 a poor third at 2.4mph. At .6 of a mile per gallon cruising economy difference between the 150 and the 175, a cost difference of $1300, and gas at $4.00 a gallon at the marine pump, it would take about 650 hours of run time to justify the added cost of the 175.

However, there are some added bennies, one of them being you get to blow off about half the bass boats on the water with the 175!
