triple vs twin on gas consumption ?
OK ! I know!
Triple are sometimes more expensive to insure and not as easy to sell, triple maintenance...
But, I'M mixed between a formula 419 triple 500' running (not sure) between 75 and 80 mph I guess, and a 42 sonic twin 500's running I guess 65 mph.
cruising speed at 3500 in the sonic must be around 40 mph
cruising at 3500 in the formula must be around ... 50mph?
My question is: from point A to point B, at cruising speed, I'M I right thinking the triple would not be really more expensive to run than the twins? Full throttle I'm sure it would be more thursty, but at cruising speed???
or more simple question, how many miles a gallons does a sonic and a F419?

not really, unless triple are a pig on gas. I have nothing financed but sometimes I try not to throw money for next to nothing more. if it's one third more gas for the small difference in speed, it's not Worth it for me...

I thought I read a 525 uses 54 gallons per hour at wot. If a 500 is close to that, I guess 35 gallons an hour at cruise. Three motors working together I assume might lower that number a bit. Maybe 28 gallons times 3?? I have no idea, but as much ground as I cover on a weekend I know I wouldn't want the fuel bill.

Every motor will have a given consumption rate at any RPM whether it is in a single,twin, triple or quad configuration. What changes is the "cruise" MPH @3600 RPM (example) and with the additional power, top end! It really is a "catch 22"
It would be very interesting to see hard numbers of an actual burn rate/ performance #'s on a similar bigger I/O boat rigged with twins and trips.
Similarly, I know of a few 32 Skaters over the years that had Trip where the owners pulled the center motor. They couldn't really justify feeding the extra motor, hammering the center gearcase/failures for the few extra MPH on the topend when they primarily used the boat midrange with the odd top end run.
It does take more RPM/fuel to run these boats at a given cruise w/twins vs trips.
Test run both boats, the twins may feel that there is enough power and gives you what you are looking for in a comfortable cruise the way it's set up or just feel like a dawg compared to the trips....

The 426 Skater V is a sweet boat with the twin oil burners - performance, longevity and 1500 mile cruise range. You would only have to fill it up once per season - LOL.
Surprised it took so long to find a home..unless it was because it had no cabin?
