largest outboard engines ?

Re: largest outboard engines ?

Eric and Rick Davis at 7 Marine may not be stopping at the 557 LSA motor. the 727hp LS9 fits in the same cowling :happy:

now that must be getting close to a magic number......1hp per pound of ob!? ( or has that number been reached in the boat racing world?)

Re: largest outboard engines ?

ok so autozone near me didn't have a puller tool for this engine that works. I rented a harmonic and a steering wheel puller but that didn't do any good. To large didn't fit right to pull. I am wondering where I can get a puller to take off the magneto/flywheel on most small engines and outboard motors. Is there a general puller that gets most/all of small engine lawn mower , tillers , chainsaws ,..etc and most outboard engines that you guys would recommend. I am stuck until I can get this flywheel off the engine.

Re: largest outboard engines ?

ok....im easily confused, and with all do respect, but where does pulling a flywheel on an unknown engine fit into this thread????

Here is the link to the EPA Clean Air award to E-TEC 2004 Award Recipients | Clean Air Excellence Awards | US EPA

Not sure how relevant a decade old clean air award is to today's emissions performance.

Welcome to the No-Spin zone..........Here is the 2012 EPA Marine Spark-Ignition Engine certification data.

try to stick to one topic per thread

KFA, I am not sure that DFI 2 cycle motors have less moving parts than an equivalent 4 cycle motor. The DI motors have belt driven compressors and pumps (Opti) and fancy fuel pumps (e-TEC). The rest of your post may not be exactly accurate as well.

Ding and Seahorse. BRP claims that buring the 2 cycle oil in an e-TEC is an advantage. They reason is that they claim 1/2 of all used 4 cycle motor oil is improperly disposed. So burning it up is more environmentally correct.

I love advertising.....

...well I suppose if you count all of the accessories (some of which are optional), but crack open the blocks and compare a typical 2-stroke to a typical 4-stroke. By design, 4-strokes have more bits and pieces. Try picking one up. Ask any mechanic which they'd rather work on too. It's no contest. The rest of my statement is also correct in that the most efficient motor is the one that is never built. By keeping an old 2-stroke running, you keep a new 4-stroke from ever being produced thereby saving raw materials, pollution, etc...It's the same reason we wear jeans for years and years and repair our houses when they brakedown. While it may be a pain to maintain them at the time, it's still far more efficient and less expensive to maintain than to replace outright. Don't let the electronics on modern motors fool you either, they're all mined from somewhere deep in the Earth and/or recycled by Chinese, child slave labor, neither of which are particularly "clean" processes. I do agree that Etec's claim that their "cleaner" because 4-stroke folks routinely improperly dispose of their used oil is a bit of a stretch, but I'm sure there are plenty of folks that do just drain it into an old jug and toss it, unfortunately :/ Of course, there's no real way to measure exactly how much. They call that "puffery" in the ad biz.

You need to start a new thread for the new topic...... We can be easily confused...... Thanks.....

Re: largest outboard engines ?

Well KFA, not exactly a standard post. Gee I think you need to count all moving parts of a motor, but that may just be me. You do realize that 2 cycle motors are usually all roller and needle bearings, and 4 cycle motors have one-piece bearings for crank journals and main journals? So the moving parts on a 2 cycle add up quickly. And whereas it costs a lot of money to replace an old motor,when they are replaced, the environment is better for it.


The rest of your post seems to indicate a little bit of paranoia. Stock up on those knives, for when the Zombie Apocalypse occurs.
