Sorry Capt but I can't agree with you on this one. A piston starts at the top of the cylender and goes to the bottom of the cylender on the intake
stroke, that is one half revolution of the crank. Then the piston goes to the top of the cylender for the compression stroke, that is another half
revolution of the crank. Now starts the power stroke and the piston goes to the bottom of the cylender again another half stroke, and finally the
exhaust stroke completes when the piston gets to the top of the cylender. 2 complete revolutions of the crank. Lets hear your theory.

A two stroke has a power stroke every revolution. A four stroke every other revolution!http://www.animatedengines.com/twostroke.html

HolA,,yep your correct !! I was on the phone to my part's warehouse at the time and posted wrong..ooops!!! being on HOLD makes my brain shallow and
not all there..I stand corrected..and since I have been building and repairing 2 and 4 strokes and diesels for over 40 years..I should be the last one
to say what I said..al well PLEASE someone fire me !!! I could use a day off!!! and also on that note we also have 2 and 4 stroke diesel's..I didn't
watch the vidio...hanging my head low!! K&T

captkw,
No problem, welcome to the human race. I make simple mistakes daily.
I agree with you on two strokes. With just a little care they just about last forever. I have a 70hp Evinrude 3 cylinder looper that probably has over
two thousand hours and still runs great. My 150 Yamaha has over 800 hours and has never been in the shop. Just new plugs and gear oil about every 200
hours.
Everyone tells me to get a new four stroke 150 because they get about 25% better fuel mileage, I just tell them I can buy a lot of gas for $14,000. I
would take me about twenty years to pencil out not counting increased maintenance!

a story
wish I had osprey'S touch,but I dont..any way about 8 years ago Im in the machine shop (2nd home) and see a nasty ate up pair of heads..ask my
machinest whose they were..with a chiteating grin he states HP (harbor patrol) what !! I say!! looking at them with a trained eye..my god they only
have had these like 2 yrs or less I stammer..machinest says 1 and a half yrs to be exact..and strangly enough I had there old commercial johnson 150's
in my boat yard that were run hard for over 5 years and were still good motors..those heads were off a pair of yammys 200hp 4 strokes..now any time HP
use the boat they flush !! (duh) and the johnson two strokes were never flushed..just a tougher build and I anit got nothing to say that is biased....
being a marine tech for over 30 years and also work on a homeland secruity vessels I have most of all the latest training, tools and know how..so
when I say a four stroke takes more care than a 2 stroke !! listen to the man that knows....OUT

2 strokes will be around for awhile but they ARE on their way out
dont fight the wave |
news is slow to get to mulege! the big buzz in the motorcycle community is all about
the new husqvarna direct injected 2 stroke dual purpose bike. ktm is also scrambling to get theirs out. take a look at the awesome snowmobile and
jetski 2 stroke power plants! go out to a district race and see all the ktm 300 xc's on the start line. 2 strokes arent going away, they,re making a
huge comeback

NEVER get a 2 stroke...old school
they are loud and stink AND are banned in many locations
plus they suck gas
later the parts will be impossible to get...
thats how "they'll" eliminate them totally
4 strokes do break and "old mechanics" hate to learn the new technolgy but the 4 stroke is a better machine |
STINK!!!! nothing matches the sweet smell of bean oil! ahhh castrolR

stink !! what stink..thats not stink!!
on my small cat I run bullet proof 2004 merc's 75 hp two stroke motors (2) and I increased the oil injection a bit !! for me a cup of coffee. heading
out the"jaws" with a bit of 2str oil is a smell that I cheresh with the first sign of the sun coming up and the gulls moving out of my way !! and
55steve.. I have the software for your E-tec..a sweet motor and a hell of a leap up from the FICHT !! our friend BOB sounds like a nice guy and hell
any one that has a light house (el farro) is OK in my book if its next to a point and the right markings ..one of us needs to take him for spin so
that he catches up with the wave..its amazing at tahoe with the newer two strokes !!! to run mine as a dealer (a) I can put on a 4 star stickeeer,turn
down the oil injection and run !! JUST KIDDING !!!!they will be knocking on my door in the morning!! K & T (a) retailer would be more
fit!!

tough one on the motor santiago, pero I don't know chit about engines.
This conversation is interesting and informative. I've had a GW22 for over a year now. It came with a 225 SWS. Damn was that thing loud and smelly
and the gas usage was crazy. Sold it and got a 4 stroke 225 with about 600 hours on it for $5000 on topof what I sold the two stroke for.
4stroke get 50% better mileage, quiet and allows, allows allows starts on the first crank. My bilge is clean since removing that oil tank. DId I
mention you can have a normal conversation while under way.
4 stroke is a big heavy b-tch. Trim tabs helped getting it on plane, but the increase in weight has dimished the MPG's because it's hard to stay on
plane a slower speeds like the 2stroke did without trim tabs.
100 hour maintenance is expensive.
No chance of installing twin 4 strokes due to weight
It's really just too dam heavy for my older Grady, so the new two strokes be great in a twin 100's if they weigh 250#'s each.

Current status:
Installed today and test run in the shop, will sit overnight and they will scope it in the morning; they have small scope with a light that they can
get into this area. If no leaks, then I will pick it up and start my on-the-water test runs next week.
Question: the shop says this motor has a low oil pressure warning buzzer but not automatic shut-off. Sooooo, if I'm running at 5000rpm and there is
sudden failure of the patch, the warning will come on but the shop thinks probably too late to save the engine. I'm thinking they are being too
conservative; if I immediately shut the engine off when I hear the buzzer, there would still be some oil pressure and some oil circulating, right?

If it was repaired with epoxy and a plate I doubt it could lose the oil very fast if it developed a crack or hole. I would think you would see the oil
slick or mess in your engine well before it siezed. I would feel pretty confident as long as it was done right. I've had JB weld out last aluminum on
past emergency repairs...even on coolant tubes that are under pressure. Good luck, let us know how it does... BTW. Boat tow insurance is cheap..
