Marin,
I read it "We run all our outboards, 2-cycle and 4-cycle, on non-ethanol fuel (as we do with our lawnmower, home generator, etc.) That alone make a huge difference in the reliability and longevity of the motor in terms of running properly." The same way and wondered about that. Re lubrication I definitely don't think it's an issue. Not at all.

Peter B,
I'd love one of those little Honda's but I don't think I could stand the racket. Flywright thinks I'm noise sensitive ... probably am. Perhaps I should just buck up and get one. Used to hate that expression "buck up". Lots of other people seem to like them as I see on Craig's List they are not cheap to buy used. I have a water cooled Yamadog 2hp so I'll wear that one out first. I think it's the same weight as the Honda though (27lbs) and I can lay it down anywichway. Not too noisy at half throttle but I can row that fast .... rev it up for that great top end rush (one more hp) and it may be close to the Honda for noise. Can't afford a new engine now anyway.

jleonard,
Your post #19 seems a big plug for Staybil. Glad to hear it. For all our domestic engines (lawn mowers ect) we use the alchol free gas but during the "season" perhaps we don't need it. Think I'll use alchol free gas and Stabil for winter though. Run dry also.

Eric-- Our outboards run okay on ethanol fuel, it's the not-running that's the problem. Ethanol fuel separates pretty quickly and starts to gum up things like carburetor jets, float bowls, and the entire fuel system in general. That's why it's very beneficial to run the motors dry before any period of non-use.

Using non-ethanol fuel probably reduces the need to run motors dry between periods of use other than longer lay-ups. But we still do it with our motors.

We use Stabil in our non-ethanol fuel but not in ethanol fuel. It was some years ago but the outboard tech at Jacobsen Boats and Motors in Ballard (they've since moved to Edmonds) gave me a lengthy discourse on fuels and additives. According to him ethanol fuel actually prevents things like Stabili from working and in fact the use of Stabil results in accelerated separaration. I have no idea if he was correct but once we found an easy source of ethanol-free fuel it wasn't something we were concerned about.

Marin that's funny (ironically) because my nephew who worked for a local John Deere dealer at the time went to a class and they said Stabil was a good additive for ethanol...but of course the JD additive was better.
I just know it has appeared to work for me.

I'll chime in here. We bought our Whaler 1-year ago new. The dealer (MarineMax) advised us to add Stabil to every fill up especially to ethanol containing fuels. The Merc owners' manual states that the motor(s) is designed to accept ethanol fuels safely. The motor is a 25 hp Merc 4 stroke. I've been doing that as directed. Have not been flushing with fresh water but I will in the future as it certainly can't hurt. I have never run the motor dry.

I always flush my E-Tec's from the screw in hose adapter for about 10 minutes and done. That's for a 40HP and 115HP though. Never run them out of fuel. Seems to work just fine and they always start up. But I never run them w/ethanol gasoline, Only rec 90.

Pretty much our program to for our 2 stroke Mercury 40hp. It's been very heavily used, all salt water. Never flushed it once myself in going on 8 years now. I do have it serviced about once a year or so. I am embarrassed to say how abused this motor has been but the damn thing keeps running like a top. May be that running it is the secret.

Stabil like most additives has been modified since the advent of ethanol gas.

Some brands have different products for different fuels..gotta read the label.

I take my 2 hp dinghy outboard off and rinse and dry it after every use. I never flush it since it doesn't have a cooling system. I store it in the lazarette between uses. I have never had a problem with fuel and I don't use any additives. It starts immediately even after a winter sitting in storage. I have had it for 5 years and have never had it serviced. Never a problem.

It is a Torqeedo

The outboard maintenance guys I have talked to stressed what Marin said: run the outboard out of fuel when not in use. I use Mercury Quickare #1 as fuel treatment, 'cause that's what the Mercury guys said to use. Evidently this stuff has sufficient stabilization for a year, but I won't keep my fuel for the new year. Fuel without ethanol is mostly unavailable in BC.

I have a 10 gal container that has a hose attachment, and I run water through my me fine when I can when cruising. I figure I can use it 4 times before it runs out. If it's raining I can fill it with water running off the boat deck. Best I can do.

Chevron 94 is still ethanol free in BC. One of the few.

No, I have no fitting on the motor to accept a flush hose. That would be an improvement. I'll keep looking for a suitable alternative. Maybe I can fashion some sort of bracket to allow me to position the cup on the intake and clamp over the aft portion of the anti-cav plate.

Maybe I should remove the whale tail and test the dink performance. Those are usually used when the dink is underpowered to help with planing. My 9.5 ft dink is anything but underpowered. If it's not needed, I could use a standard flush accessory.

FlyWright, I bet you'll find the bow climbs for the sky and you need to shift weight forward to get on a plane. The little skiff I built last year would do that to the point I could not get it on a plane by myself. Put someone in the bow and it jumps on plane. I installed some spring loaded trim tabs, Smart Tabs, on the transom and it cured that problem. I think now I'll take off the tabs and add boxes on either side of the engine that will extend the bottom aft and increase floatation at the stern. My skiff is not under powered, it just needs more lift aft.

If you find that the bow is hard to get down after you take the wing off, consider installing Smart Tabs instead. They'll give your butt a lift and leave your engine clear for a flush attachment.

In a couple days, then we'll be heading back in August.


I always wanted to build one of those little skiff like I pictured.... Good luck on the extension.

You might be right, Parks. I got this motor from my friend with the tail installed and have never tried it without the tail in place. I'll be out next month for an extended anchorage, so I'll mess with it a bit. I'll report back!

I'm with parks. When we re powered our 12' tender from a 40 Honda with a dolphin to a 40 Etec with no dolphin you can tell the difference.
We're putting a dolphin on it when we get home. The boat goes vertical for 3 or so seconds then plains out and that's with my modest 125lb self in the back. With a grown man in the back it'd get interesting.

Hey Marin,
How long would you say a "period of time" is? I've never run my outboards dry as I thought that lead to drying up of carny gaskets which crack and leak. I just bought a brand new Mercury 6hp 4 stroke and reading all of these comments about gumming up has me worried now so might start running dry?

Climate/warmth probably has something to do with it and evaporation of the gas...

The ONLY time I had a problem is right now. My outboard gummed up in 2 months of 60 to 90 degree temps. Part of the problem was the age of the gas to begin with...it could have been as much as 6 months old. Usually that's not the problem...just the evaporation.

Oliver what you really need is a longer boat .. not a "Dolphin". Long boats rule, Short boats squat.
