considering 4 stroke

oxbeast1210 · 02-09-2012, 03:42 AM

I'm considering going to a 4 stroke on my boat. It currently has a
1993 150 evinrude on it runs great and pushes the boat great. I haven't had any issues with it .
Mostly I wanted to know if you guys know of anywhere that sells used four strokes or is it best to just get new? Also I'm not sure what the boat weighs its an older 21 stamos cruddy cabin what HP would y'all recommend I know 4 stroke weight a lot more .would I be able to use a 130hp or would that be to much strain on the motor? I understand that there is different variables to consider so please let me know if you need more info.

I should have asked this first but if my motor is running fine should I even consider repowering? How much better are they in fuel for comparable HP?
Thank you in advance.

My opinion, Stay with 2 strokes they are lighter, no valve trains to be adjusted every so often at great expense and cost more. I have a 150 E-tec on my 21 ft Wellcraft over 400 hours one minor injector problem corrected free under there 5 year warranty. Also doubled my mileage from old carbed engines. PM sent..

Lots of factors to think about. I tell my customers that boat owners don't usually get rid of good used engines. If you do find one, have a trained mechanic check it out that has the proper equipment. Not ole Bubba down the street.
The four strokes are much cheaper runnng but you do need to keep up with the maintance. They have fewer fuel problems than the carb'ed engines and run a lot smoother. As for weight, comparing new 2 strokes to four strokes, there isn't much difference. They have really gotten the weight down. In fact, there is a few four strokes that actually weight a bit less than their two stroke counterparts. The cost savings in fuel greatly out weight any extra fuel burn from the weight.
Now for the down side, if it breaks, its costly to repair but properly maintained engines have very few problems.

Sealark, thanks for the info about the etec. I've been thinking about going from twin 150 four-stroke yamahas to twin 200 etecs. It looks like I would cut about 90 pounds in weight off the back while gaining 100 hp. I'm curious how loud the etecs are in comparison with the yamahas and if they smoke at all? One thing I like about the yamahas is the low noise when cruising and low smoke (a little at startup) but the overhauls are a stinker. I've heard fuel consumption is about the same and the performance charts seem to indicate that. Etec has some incentives going on right now.

The Etec is an excellant engine and they are finally shaking off the bad image of a few years back. But they are a different breed of engine and anything learned from other engines cannot be applied to Etec. My son is the USMC Recon team specialist for MFE version of these engines and trains the teams on their operations. I went through some of the engine training and learned enough to know that I didn't want to jump into one without someone smarter than me around. If I get one that is out of warranty, I call him first. Like I said, excellent engine as long as there is a trained specialist close by if they have a problem. I might have the pretty certificates on the wall but unless I was working on them daily, I still don't feel confident. You have to forget everything you ever learned about engines and relearn a competely different idea.

Look at the ratings the E-tec is one of the highest and my 150 doesn't smoke and it's super quiet. Kenny Mann at emerald coast is an authorized dealer. As for problems with E-tecs compared to other outboards, The e-tec is a standard electronically controlled 2 cycle engine just about like all the newer engines on the market today. The software and easy hookup that is readily available is a breeze to hookup and find just about any problem on the engine. I had my 150 running rough and hooked the software up and found a #4 injector bad after 420 hours. Took it to Kenny at Emerald coast and it was fixed within 2 hours after new injector arrived in two days. my engine has a 5 year warranty with it. my cost was 0$. Can't beat that
