Re: yamaha 225 efi 2 stroke vs. 225 4 stroke
Sometimes the manufacturers have been at fault, I have heard stories like that for nearly every motor around.<br />heard bad stories about optimax, <br />heard bad stories about OMC fichts, (not bombadier though, yet to hear a bad one from them.)<br />heard stories about the end of cams snapping off suzi four strokes, heard some stories about honda 4strks as well..<br /><br />They are all engines that work on the same general principles.. (internal combustion.)<br /><br />all are capable of having mechanial failures, of having design failures, (old fichts are an example here.) and of having material failures..<br /><br />both use standards that have been around for yonks for their basic structure.. they are both only refinments of engines that have been around for 50 years...<br /><br />I still say its much of a muchance.. <br /><br />I'd say the biggest reason to chose one over the other is "which one has the better support" over the others.<br /><br />In Australia, anything with "marine" in its name somewhere is 4 times the cost.. 4 strokes are incrediably expensive over here... you have no idea how expensive.<br /><br />We have no laws at all regarding emmisions.. (except that if you create a big spill, you pay to clean it up..) and two strokes are a much cheaper.. but still expensive.<br /><br />In Australia, a 10 year old 225HP would still go for around 12000 to 15000, (multiply that by 0.58 for roughly US dollars.)<br /><br />A honda 225 four stroke goes for around 23,000 dollars AUD. not cheap, thats the price of a new family car.. (ford falcon or GMH commodore.)<br /><br />who can afford that? certainly not me...<br /><br />so again, its personal choise as dictated by your wallet, its contents, support in your area, weight, space etc...<br /><br />Don't write off the two stroke yet.. its developing fast.. and it is the more power efficient format.. (ie: max Hp per ci)it just has some issues that need to be worked around.<br />they are getting there..<br /><br />I still think that one day crankcase compression will be replaced by a basic rotary supercharger, meaning that all transfer ports can be removed, flow characteristics improved. oil in crankcase<br />for lubing duties, throw in DFI and variable exhaust expansion etc etc..<br /><br /> if they ever want to mass produce a 300-450+ HP outboat motor, they won't do it with 4 strokes. (at least not initially) it would be too heavy. but a two stroke with the above characteristics could do it... we already know that in equal tune 2 and 4 strokes of the same size the 2 stroke wins every time..<br /><br />they just need to work on improving the design.<br />Don't solely decide now, things change all the time...who knows what will be the trends??<br /><br />pretty much all failures with recent motors have been found to be a design fault..<br /><br />As is pointed out many times on this forum, the majority of outboards don't die from wearing out, they die of neglect or some accident.<br /><br />Its all about choise, and we should all be delighted that we have that.<br /><br />having said that, if I was looking for a 10-70 HP outboard and cost wasnt' an option, I'd probably go a fourstroke, if I was looking for a 225hp, I'd start by looking at the new fichts.<br /><br />regards<br /><br />Frank
