More fun with Verados

Following the advice of a poster in another thread to check out Boston Whaler's performance reports for comparison purposes, I did so and noticed a number of Whaler's performance reports now include results with the Verado 250 and 275. Still curious about the much hyped performance, I compared the performance of the Verado to the Optimax equipped boats. What I found is that while the acceleration of the Verado 250 seems to match the Optimax 225 for the most part although the Optimax equipped boat was 500 lbs heavier, that better acceleration out of a 4-stroke comes with what appears to be a large penalty of WOT fuel consumption.
Compare the 305 Conquest test results. A pair of 225 Optimax put it on plane in 5.1 seconds, pushed it to a top speed of 44.3 MPH while consuming fuel at a rate of 41.9 GPH and had an optimal cruise speed of 28.9 MPH at 4000 RPM yielding 1.36 MPG. The Verado 250 pair put a 500 lb lighter Conquest on plane in 5.7 seconds, pushed it to a top speed of 44.9 MPH while consuming a whopping 57.8 GPH, and Optimal cruising speed was 26.4 MPH yielding 1.35 MPG.
The data suggests that to get the low end torque of a conventional 2-stroke you also get the WOT fuel consumption of the conventional 2-stroke as well as a couple of hundred pounds on the transom.

I noticed the same thing, Peter, when checking out the performance of the Mercury 250 Verado four stroke compared to the "Mercury" 225 four stroke and the 225 Optimax on the 240 Outrage.
The difference in wide open throttle speed was about four or five miles per hour. The fuel consumption data for the "Mercury" F225 was not listed. (I wonder why?) Seconds to plane and seconds to 30 MPH for the Verado was impressive and it does look like this is where the motor will shine.
I was amazed that the Mercury 250 horsepower Verado would burn 28-29 gallons per hour at wide open throttle. My 2003 Mercury 250 horsepower EFI, according to my Smartcraft, burns around 27 gallons per hour at wide open throttle (5800 RPMs).
When I was shopping for a motor over the winter I was looking for a 250 horsepower motor. The motor I was most impressed by was the new Suzuki 250 horsepower four stroke. Around 600 pounds, wide open throttle fuel consumption of around 22 gallons per hour and a gear reduction of around 2.30 (it turns a 16 inch diameter prop) really made this the best fit in a four stroke for my boat. (1997 21' Outrage) Priced at around $16,000 on the transom and out the door made it attractive also. Buying in the first year of production and the lack of dealers in my area close by were factors I also considered.
The Mercury 250 EFI for $11,000 (new) on the back of the boat was what I went with because of price and the good reputation of the big block Mercury V6 EFI motors. The dealer network for Mercury is extensive and I know the dealer I purchased it from. I really like the motor alot and I am very happy with it. It does have a hefty appetite for fuel though.
