Re: fuel consumption

[drr]

Thanks for all the replies to my post, yesterday, I have a 1991, 90hp evinrude and wondered how much more fuel I would burn getting a bigger boat with a bigger motor, I am guessing probably not that much more from what I can tell, if I get a newer model. anymore input???? thanks again

Short answer is It depends.   ;D ;D

Longer answer:  Depending on what you are comparing, and the load you are pushing.  A new 4 stroke or DI engine will get better fuel economy than an older carburated model.  Putting a new 90 on your existing boat, you might see a difference.  But if you upgrade to a bigger, heavier boat with the new power, you may not see an improvement.

That said, with any improvement, it will likely take a long time to run enough gas through the motor to pay for the difference in costs.

drr, I'd think kirk is on the money.  I had an '86 carborated 150 Yamaha on an 18ft Ranger.  The motor ran like a champ, no complaints about how it ran.  Just drank gas, and didn't like changes in elevation so much (2500+ feet).  New 225 Optimax on 20ft Ranger, better performance and much better on gas.  I'm sure the same could be said for the four strokes, but I understand the Verado's gas consumption is the same as an Optimax.

I HAVE A 90HP ELPTO MERC ON A 17' TRACKER TARGA SC WITH A 94" BEAM AND I GET BETTER MILEAGE THEN MY FREINDS 16'- 74" BEAM MIRRORCRACFT WITH A 35HP TILLER HIS MOTOR IS ALWAYS RUNNING WIDE OPEN JUST TO GET 2 PEOPLE AND THEIR GEAR TO 15 - 20MPH WERE AS I CANS JUST CRUISE TO THAT SPEED PLUS I HAVE A STAINLESS STEEL PROP WHICH ALSO HELPS. SOMETIMES YOU CAN BETTER MILEAGE OUT OF A BIGGER MOTOR ESPECIALLY IF YOU KEEP THE SAME SIZE BOAT.
