I know this is a little off topic but it looks like you have the fuel flow meter on your hds. i just installed that on my boat but have not had a chance to take it out and run it. how do you like it so far and how accurate is it??
|
I like it, seems to be accurate. It is very responsive. My MPG goes from best = 3.05mpg at 29mph/3800rpm@9.5gph (My Boat/engine does not like to run this speed, wants to speed up or fall off and slow down) to worst = 2.16mpg at 39mph/5200rpm@18gph (WOT)

Hummmm.....2.91 on a carbed engine. I'm shocked and impressed.

Thanks. My Yami is VERY light weight, only 411 pounds according to the owners manual

I think that you may be ignoring the much greater efficiency of 4 strokes at idle and trolling speeds. Not saying that your calculations are wrong, just that old 2 strokes waste a ton of fuel at lower speeds.

Maybe. But to the best of my knowledge my motor idles and trolls at 1 GPH and at 4.5 mph so that is 4.5mpg. How does that compare with 4 strokes?

I don't think you'll get more than 8-10% improvement with a fourstroke, at best.

My thoughts, exactly...
