2 stroke vs 4 stroke on 1996 Osprey 225

[MarshMarlowe196]

The 4 stroke or DFI 2 stroke should yield about 10-15% better fuel savings.

 

Where does the 10-15% increase factor come from?  Is this WOT #’s?  All the documentation I’ve seen on conventional 2strokers vs. injected 2 strokes/4 strokes is showing a 20-40% increase in fuel economy for the latter @ cruise, with variable factors. 

 

Jolly, I found this on continuous wave. It may be helpful

4 strokes only shine from about 4.5k down to idle where I mainly drive. A 225 Johnson with carbs will burn about 13GPH at 4k(23.5 wot). The 225 4 stroke burns about 9, so does the DFI's. At WOT the DFI and the 4 stroke burn the same about 21+. So compared to a conventional, antiquated 2 stroke like my OceanRunner or say a 100GT Johnson, 4 strokes are gas misers. I would love to have a 4 stroke on my Hydra sport because 4gph at cruise is a big savings, but not worth $16k to upgrade......yet.

 
For the sake of discussion, and I’m only speaking  from the experience of owning my Suzuki for 5 years now, the regular maintenance called out in the owners manual is well within the capabilities of any average wrench turner, which I believe everyone on this forum can call themselves.   Still haven’t had any problems with my engine, never had to  take it to the dealership for any maintenance.

Thanks fellas.  

My current motor runs good so I would be foolish to fix something that is not broken it just seems that everytrip is costing $100 was a tough pill to swallow.  I was used to a smaller boat with a smaller motor....  I am setting money aside for summertime fuel....and waiting for spring.  Think warm weather. :P

Sound thinking Jolly man!
Give her some TLC and keep up on the maintenance and she'll give you many more years of service. Gasoline and oil will cost what it costs and like everything else in life we will shift the financial priority as needed. Still better than dropping $15K for an outboard, that will depreciate 50% in 5 years regardless of brand and yield negligible savings over its life with average use.

Jolly does your boat have a flow scan fuel flow gauge?
