661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[Big_Wood]

THIS!
Yammy outboards btw spec a 100:1 mix ratio. However, when I ran a fleet of them commercially I always thought they maintained full power longer when ran at 50:1.

i know, i'm a marine tech LOL i to think that the 100:1 is a stretch for premix applications but the way those oil injections systems were working before they went to direct was pretty sweet. although it sure sucked when they failed LOL.

Some of those injection sytems didn't even pump at idle. Always worried about inadequate lubrication when trolling for hours on end, but they seemed to work ok.

i run honda myself. they are picky in salt water applications and suffer some major block rot issues if not taken care of but man are they reliable.

No, it doesnt. Red oak always makes alot of dust. Especially the standing dead I have been cutting.

Evinrude has about zero exposure in regards to the Canadian commercial use market.
I do like the Etech's.

I worked at an OMC (pre dissolution) and Suzuki marine dealership in college. Hands down Suzuki made the best outboards. And I was a die hard Yamaha guy.

evinrude and johnson was always a big deal here my little boat motor is nothing to brag about it is only 9.9hp.
seems to push the 14ft john boat pretty good.

they didn't pump much at idle but they all pumped. they mix before it even hits the carb. unless you talking about after they went direct. direct still pump at idle too but VERY little. i liked some of the older merc/mariner gear driven ones. they seemed to be most reliable anyways. the ones running on vacuum worked when they worked. i'm kinda done with 2 stroke outboards at this point. i had a 75 etec that cooked 2 cylinders and then another 90 etec that cooked 1. the 90 sure lasted a long time though.

OMC absolutely ****'n sucks!!! LOL best thing was bombardier taking them over. now were getting into opinions so maybe cut it out otherwise we'll all be arguing in no time LOL

my OMC doesn't suck but it will embarrass a lot of machines that do the same job.

you talking about the M series with the oil injection system
i had one and sold it but the injection system was bypassed.

The best 90's have ran where Yami, three cylinder. They would easily go five years with out so much as a plug change when ran commercially.

What about the Harley golf cart? How does that run on dino oil.....oh wait a minute....didn't you say....aahhh nevermind

You ain't gonna' let me forget that PITA... are ya??

Yeah... when I switched that to full synthetic I noticed the piston was really clean when I replaced it again... but it ain't made a difference on how long the piston lasts before the rings break. I'm still running full synthetic in it (Amsoil Interceptor) because for $9.90 per quart at the local fleet store it's the cheapest I can do unless I wanna' use some Pennzoil "yellow bottle" sludge... I don't use Pennzoil anything (but that's another story). I use Interceptor at 50:1... at 40:1 the muffler dripped a little oil on the shop floor.

The Harley golf car has a 250cc engine... I don't classify it as "small 2-stroke OPE".

the price has really jumped in recent years a 1 gallon mix bottle of it is 3.49 around here.

I buy the bottles sized for 2½ gallons... if I remember correctly the last 6-pack was less than $15.00 at my local Stihl dealer (likely still have the receipt laying somewhere).
The little 1 gallon bottles are always the most expensive... in any brand.

Correction; I just checked... $11.75 for a 6-pack of 2½ gallon size bottles... and a 6-pack of the 1 gallon sized bottles is $7.45 (a single bottle is $1.25).
I'm not sure why it's so expensive where you're at jakewells??

Further to ship? It's more "exotic" where he's at?

Sorry but there's an awful lot of hype and hoopla about Amsoil up here.
