Own a 1997 Grady White Islander with twin Yamaha 150 Salt water series 2,
fuel comsuption at average RPM is high and have been thinking or repowering but can`t decide between the new Yamaha 4 strokes or the Evinrude Etecs. Can some one give some insight..
first time boat owner!
I re-powered a 29 ft Fountain (tournament boat) that had twin Mercury 225, that kept blowing up, with twin Suzuki 200 4 strokes. Not only do these get the same speed but they get double the mileage and they are lighter. They are not even broke in good.( 35hour) They should get a little better mileage after a few more hours. Quiet is not the word for it. I pull up on a rig and forget they are running. You don't smell that oil/gas burning smell ether.
I have twin 90 4 stroke Suziki on a 258DLV Carolina Skiff. I had the chance to get the E Tec's but got the 4 stokes because of the reliability and long life of these motors. I have a friend with almost the same setup with the ETec's and our speed is within 2 mph difference. He is running 3 blade props and I am running 4 blade props. WOT for him is 6000rpm and I'm at 5500rpms. I get 1mpg better fuel mileage, which is 4 to 5 miles per gal. My 4 strokes are quieter at WOT. The weight difference doesn't really matter.
3 years without a maintenance. " WHAT A CROC". You have to take it in at least 2 times the first year, if you use it alot, to have the computer adjusted. There is no breakin because the computer is set to dump lots of oil in during this period. Thats why you have to have the computer adjusted now and again to cut down on the amount of oil. I got this info from a mechanic for ETec.
The only maintenance for the Suziki is the first oil change. They reset your computer, change filters and spark plugs and make sure there is nothing like metal in the oil or filter. After that you can do it yourself.
The 4 strokes Suziki is also cheaper to purchase. just my opion
I replaced my two stroke yamaha with a four stroke..they are great engines but high maintance don't know anything about the e tecs but they seem to be pretty popular around here.
Live life before it lives you
I'm running a 60 and 225 Etec, other than injector issues with the ethanol, no problems at all...
I also have a 150 and a 115 4strk Yammy, other than injectors, not one hiccup.
You'll save some money on gauges going with yammy, but other than that, both motors are real nice.
You will find a LOT more info at this thread about this same topic.

In reality, this quote and the following assumptions neglect the full picture because they neglect the entire low budget two stroke market. Here in CA, where 4-stroke is now king thanks to non-HP injected two-strokes being outlawed. People were driving to Nevada to buy cheap carbureted (or non HP injected) two strokes because of the lower weight, the higher low-end torque, and MOSTLY the significantly lower price (thousands of $$$ on large motors). Most anglers with families stretch to buy a boat and motor. They cannot afford to go out a few years later and spend $15k to repower, plus a $1k to install the motor, $500 for a new prop, $500 for new controls, and 1000$+ in sales tax. The choice is not always about performance or reputation. Sometimes it is about $$$. When I was looking to repower, and saw the $17k-$18k price tag for a new Yamaha HPDI, I thought twice about ti. Now, Yamaha has kept their 4-stroke prices down (below the HPDI). Evinrude prices are less, and Suzuki is the price leader (at least where I live).
I also see the comments about Optimax, etc being the same as ETEC. While they are all direct injection motors, the technology is quite different. The ETEC has a simpler, lighter, lower cost design with fewer parts. Their solenoid-like injectors are far different than the expensive, high-pressure pumps used on most other HPDI engines. There is a huge differenc from an engineering standpoint. When I hear them casually lumped together, I think that the person making that comment is either biased or not knowledgeable about the subject. Another example of some one comenting on something about which they are not knowledgeable is the comment about four strokes having better fuel economy than the ETEC. ETECs have comaparable gas mileage to four strokes, some claim even better mileage, but your real mileage is dependent on your setup and boat.
This thread is great entertainment, but you have to take the time to sort out the facts.
