We have a 10' Walker Bay for a dink. Over the winter I bought the tube kit to add stability and bought a 1982 Evinrude 2hp on e-Bay ($350)for a motor. Finally got around to seeing if the thing runs. Well, after some tweaking, change of gearcase oil and a new spark plug I pulled the rope and it works!

Seems to run fine but certainly more vibrations and noise than our Honda 9.9.

The Evinrude is superlight - 22lbs - and should propel us. But the noise bugs me a bit as does the slight blue smoke at higher speeds.

So, is the vibrations and noise and slight blue smoke typical? I have never had a 2 stroke before but I suspect this is how they are.

Tryin to decide now whether to keep it, put it on e-Bay and buy a little Tohatsu, or go back to rowing.

Suggestions??






We cannot direct the winds but we can adjust our sails.

yep yep, one cylinder = lots of viberation. The blue smoke is normal.

Well Randy, you're ahead of us, at least cost wise. It cost me [url="http://www.catalina-capri-25s.org/forum/topic.asp?TOPIC_ID=16332&SearchTerms=outboard,repair"]$250 & a lot of aggravation[/url] to get my little Mercury 4hp that I got off of CL with the Avon running properly.

With my <i>vast </i>experience of three whole 2 stroke engines, I'd say the smoke & vibration are pretty normal. Although a new Tohatsu would always be nice (bet you have one by the end of fall...with a SS prop).

Steve, here's your [url="http://www.westmarine.com/webapp/wcs/stores/servlet/producte/10001/-1/10001/14428/377%20710/0/earplugs/Primary%20Search/mode%20matchallpartial/0/0?N=377%20710&Ne=0&Ntt=earplugs&Ntk=Primary%20Search&Ntx=mode%20matchallpartial&Nao=0&Ns=0&keyword=earplugs&isLTokenURL=true&storeNum=116&subdeptNum=319&classNum=319"]earplug link[/url] so you can delete yours so we don't have to scroll back & forth to read the thread.

Are those ear plugs Marine grade?

Nice little engine Randy. a 2 stroke is pretty reliable too. Make sure you put just enough oil and not to much into your gas blend. If I were you, I would keep this engine.

Switch "Format Mode" from "Basic" to "Prompt" (top left of the blue editing box). This makes all hyperlink, picture, etc, insertions much easier.

Had two strokes. Much happier with my Tohatsu and Nissan 4 strokes. I travel about a mile in my dingy to get to my boat and wanted something I could plane with when two adults are aboard. We travel against a 3 knot current at the worst of times. Originally I had a 3HP old Johnson 2 stroke. Reliable little engine but loud and not enough power to plane with even me aboard. Then I bought a 9.5HP evinrude from ebay. Ran good at first, then the lower unit started having issues. Seller dissapeared etc etc. So it is in the garage until i can fix it. Bought the Tohatsu after that. It is so nice and quiet and pleasant to use. If your 2 stroke craps out, I highly recommend it so far.

For vibration, the number of cylinders means more than the strokes--in fact a one-cylinder 2-stroke will generally be smoother than a one-cylinder four-stroke because it's firing twice as often per rev. I have a Honda 2, and it's <i>not</i> smooth or quiet! Part of that is that it's air-cooled, which is good for durability and weight. But even after a winter, it started on the first half-pull, and goes practically forever on a pint of plain gas, with no fumes. Your Evie should serve you well--except for the standard blue smoke.

Randy, we used to have the Johnson version of the that engine, and are still sorry we sold it with our old dink, because i could pick it up with one hand and it was great for local anchorages that didn't require our 9.9 hp "beast" to be installled (with our Garhauer lift). I say keep it, especially for your application.

Thanks all for the responses. We're going to keep the OB. We plan to do some exploring of shallow areas on the margins of the lake in the next couple of weeks so we'll use the dink and give the little Evinrude a trial.

Next question. The Evinrude weighs only 22lbs. Do you think it is OK to leave it mounted on the Walker Bay 10 while we tow the dink in the San Juans? We do not expect significant wave action since the waters are relatively sheltered. Or, as an alternative do we lay the Evie down in the dink or clamp it to the stern rail of our boat? Clearly, leaving it on the dink would be easiest.

Thoughts?

At 22 pounds I would clamp it on the stern rail for except for a short tow. I would hate to swamp a sweet little engine.

Towing an engine on a dinghy is questionable. I've done it in sheltered waters in the California Delta, but don't do it anywhere it may be an issue. Same waters on different days with different weather result in a different answer. Only you can tell. But after doing our "big" engine on the Garhauer lift, I fondly remember those days when I could single hand the old Johnson off the back of the old dink onto the stern rail bracket. Your motor, your choice.

Well, we took the dink out to the lake today and fired up the little Evinrude to see what she's got. Spent about an hour touring a marshy end of the lake and seeing all sorts of wildlife. The Evie did just great and is definitely a keeper. Also our first time on the WB10 with the tube kit attached. Made all the difference in the world with stability.

That's my daughter, Jean. She's in town from Seattle for the USA Olympic Trials - track and field. She got a kick out of sitting on the bow with her feet in the water. You know any nice 24 year old guys with a job?

Besides the possibility of a flipped dink,... if you're towing under sail, a dinghy creates some drag, and leaving the outboard on the transom (even tipped up) adds <i>substantially</i> to that drag by causing the stern to dig. If you happen to sail or motor into a squall, the motor multiplies the odds that the dink will flip and turn into a sea anchor tied to the <i>wrong end of the boat</i>--I know people who've had it happen, and it can be a BIG problem when it does.

Dave, point taken. I will either clamp the outboard to the stern rail or lay it down in the front of the dink and lash it there.

Towing a dink in the San Juans would look normal, you've been here before.
The engine noise and smoke is not the norm.
When you enter or cross the Strait of Geogia this year I'm sure you will make a wise decision based on the conditions, tow or no tow .
Almost all my picture posts show someone pulling a dink.
If you have a sudden, huge, decrease in speed you have become a new club member and I'm not sure how Bristle found out about me, probably a previous post but it's not a big deal unless you've stored some thing in the dink you should not have.

I've had the dink flip once with a motor attached, and that was enough. 3 men at a dock couldn't break the suction. Then there is my friend whom we met during the remnants of Hurricane Ernesto who was soloing a Pacific Seacraft 37 from Maine to the Cheasepeake and had the walker bay with inflatable collar just pull the eyehook straight out of the boat! (That's how we met him - he came in a went out in the storm to go to the beach side and walk the beach looking for his dink). Another friend on a Beneteau 35 - it's for sale - lost his dink in the middle of the night while towing it off Cape Hatteras.

IF we tow, it is for short distances with no engine, oars, nothing aboard. And weather conditions are optimal.
