jhoffman Posted May 27, 2008 Posted May 27, 2008 Let me start by saying I am in my search for a new boat. I finally landed a job with enough income to justify something brand new and although my house is old, my truck is an 02 darn it, I WILL have a NEW boat before the end of this year. I see the tracker lineup is really pushing the two stroke motors out the door. Checking the Mercury site they dont even mention the two stroke anymore. Are they done manufacturing these? Is this why they want you to buy that motor as a "powerup savings"? Whats everyones input on the two stroke? I assume from my motorcycle days they are snappier, easier to rebuild but need to be opened wide often to prevent fouling of the plugs. How is the fuel economy vs the EFI, I assume slightly lower, is the trade off in fuel consumption worth it to save $2000? Any input appreciated. Quote
HPBB Posted May 27, 2008 Posted May 27, 2008 they are pushing them because they are cheeper and keep the cost down on the boat package, and for most people the cheeper it is the better. not saying the 2 strokes are bad. Yes they are not on their web site. Why? don't know. I have a 2008 booklet from a dealer, and a 2008 guide in BWB mag, and they still sell & make 2 strokle, only 3 models, 50hp, 90hp, & 150hp. The 2 strokes are lighter and easy to run, they do not get the milage of the opti or four stokes. if your looking for the most bang for your buck, don't run that much ( so the mileage will not effect you) and your waters are not restricted to 2 strokes, and want to keep the weight down. then the 2 strokes might be right for you. I am looking to repower my boat, and $$$ is always a issue. I was looking into the 90hp, which was my max hp, well I was able to get the max hp change by the state to 115 so I will be looking for a 115hp now. if you plan on keeping the boat along time, and use it alot then you will make back that $2000 in fuel savings. atleast in the 90-150 models. at the 50hp. I think I would still go for the 2 stroke. I have two buddies that bought 18 footers at the same time, one has a 150 opti and the other a 150 2 stroke and the opti get way better milage added this after reading past post: the 2 strokes he is talking about are old style efi and carb. I know the 150 is efi, and the 90, 50 are carb. the main thing is price. here is what is stated in my booklet. Its all about up front cost. and for alot of people, that is all they look at. If I have the $$ for a new motor it would be a DFI (optimax), but when money is tight the lower price and lighter (old style) 2 strokes may look good for many people 50hp 2 stroke oil injescted (carb) 50 hp 4 stroke weight 204lbs 248lbs cylinders 3 4 base price $4,800 $6,400 90HP 2 stroke 90HP optimax 90HP 4 stroke oil injected (carb) 2 stroke dfi weight 305 360 399 cylinders 3 3 4 base price $6,795 $8,320 $8,680 150HP 2 stroke 150HP optimax 150hp 4stroke efi oil injected 2 stroke dfi Verado weight 407 431 510 cylinders V6 V6 4 base price $10,050 $11,610 $12,650 Quote
Super User Jig Man Posted May 27, 2008 Super User Posted May 27, 2008 When you talk 2 stroke do you mean carbs. If so that technology is slipping away and not even allowed on some waters. The electronic fuel injection 2 stroke motors are in somewhat of a decline because of fuel efficency. The direct injected 2 stroke engines are as fuel efficient as the 4 strokes and a lot lighter in weight. I think you will probably see the DI motors become the only 2 strokes available in a few years. I don't know about carbs and EFIs but the tech who looks after my DI says that I only have to run it to 4500 rpms to keep the carbon build up off. Quote
AnthonyRSS Posted May 27, 2008 Posted May 27, 2008 I wouldn't even consider buying a new carb motor. Fuel injection is so efficient and painless. The Opti is a 2 stroke. It is direct injected and gets great mileage, but you have to pay a premium for the motor. Quote
Super User Jig Man Posted May 27, 2008 Super User Posted May 27, 2008 ELPTO - Oil Injected Electric start/Long shaft/ Power Trim/Oil injected a two stroke carb engine. I wouldn't buy a new one. EPA rulings are making them hard to use on many waters. EFIs aren't much better. Quote
The Next KVD Posted May 27, 2008 Posted May 27, 2008 I would have to say go and buy the optimax version. Even though I don't run mercury I would go the DFI way. I just wish yamaha made a 90hp DFI version of the HPDI. Quote

EPA rulings are making them hard to use on many waters. EFIs aren't much better. Why wouldnt the EFI be better for emissions its a whole different ball of wax. The boats im interested in dont come with Honda's or id put one of them on it. I gotta finance it all in one shot. Quote
Olebiker Posted May 27, 2008 Posted May 27, 2008 The Evinrude ads have me scared that a four stroke will need a lot of service that only the dealer can provide. Is that true? Quote

Jig Man when they talk two stroke they are refering to the type of engine. Two strokes take two engine revolutions to take in fuel, compress, fire the cylinder, and discharege the waste. Then it starts over again. Quote
Super User Way2slow Posted May 27, 2008 Super User Posted May 27, 2008 Not getting in on this debate but somebody had better learn a little more about their engines before they start posting how they work. A two stroke engine only takes one revolution of the crankshaft to make a power stroke (spark plug fires everytime the piston comes to TDC) a four stroke takes two revolutions (sparkplug fires every other time piston comes to TDC). Two Stroke; one piston down stroke and one piston up stroke = one revolution Quote

I should know better, I built drag racing engines for years and set many records with them. Have no idea what the heck I was thinking. Please excuse me. Quote
