Default 90 HP E-Tec vs. 90 HP Yamaha 2-stroke - weight matters

Like screaming fire in a crowded theater, here it goes:

The 3 cylinder 90 hp Yamaha 2 stroke is probably one of the most reliable and highest real-power to weight ratio motors ever made. It's pretty well accepted to be a tank of tanks. It's going to be phased out soon (if not this year) due to emissions requirements. Even though it's a carbureted motor, its only real competition is the 90hp E-Tec. The Yamaha is still available new, in box.

320 lbs - 90hp E-Tec
261 lbs - 90hp Yamaha 2 Stroke

In a flats boat application, where 60 lbs on the transom means 1 or more inch of draft, any reason to go for the E-Tec rather than the Yamaha? For the purposes of this discussion, assume that the 60 lbs on the transom really matters.

I have a 2005 Yam 90hp motor.
Always starts ups easy even in single digit weather when hunting on LIS of those sea ducks. Can't complain about the reliability but the fuel usage is quite bad, getting 2 mpg on an aluminum 20'cc.

Tough call........ It's like leaving fish to find fish..... I know of many 90 Yams, they're like the 70 John Rude and the Energizer Bunny... But hey, it's 2008, carbs are going away and Etec is here and doing it right!



edit: That said, I personally would be buying the Yam because of strong relationships with my dealers for many years. With a Etec, I would have to look in the yellow pages to see who the dealers are and start over again! I doubt the well qualified guy (non-dealer) that has taken excellent care of my JohnRudes for 20 years is Etec certified....

I need to know too as I am repowering (for the 7th time) next year and want my twin 90 Yammies. A friend has the idenical boat with 90 omc and it's like night and day. Say it isn't so.

According to the BRP supporters, weight means everything.

Here's my take on that question. No doubt weight matters, but it does depend very much on the actual hull you're mounting it on... If the hull is very, very light (one of those composite sandwich, vacuum bagged, kevlar reinforced, etc...) then the weight difference on the transom would be noticeable. For my older Maverick - you'd never even notice it. Here are the two downsides of that Yamaha 90, it's a great motor but there are a few little items... the first is the noise level. The difference between the Yam 90 and my 90 E-Tec is dramatic. I had to run a skiff similar to mine for a week and the Yammie on it gave me a headache every day since I was running a full hou'rs worth at the end of each day. With the E-Tec you can actually talk to the angler next to you at any speed - that's just not the case with the Yammie. If I'd never run an E-Tec I'd have just accepted those noise levels and learned to live with them...

The second difference is a lot more subtle, the Yammies that my friends own (lots of them) are a bit temperamental when starting first thing in the morning. Once the operator learns the specific moves to make they're just fine, once started that first time they're an easy starter all day long -- but I've watched more than one guy who really had to work to get one of them started, right next to me at the ramp. If it was a friend I'd offer to kick start it for him, strangers were left strictly alone since that kind of stuff is enough to make anyone cranky.... The E-tecs are night and day different in that regard, starting first time every time with no choking, throttle advancement, or any magic incantations. If your battery is up to snuff, the motor fires and doesn't quit - even if it's been sitting for several weeks.

Both of these items are relatively minor, but once you've run the E-Tec they're pretty obvious. As always with motors, the brand or make is a lot less important than having a dealer or service outlet that you trust.... that's just worth everything as far as I'm concerned.

Yes, I'm lucky enough to be on BRPs guide program, no I don't get any support after the initial purchase and my opinions are my own...
