    2 Cycle Mix Snafu

    Here's one for the books. Being the world's worst mechanic, I have been having my 2 stroke outboards professionally maintained according to the book since the late 80's. So, I was completely baffled when my motor died in the harbor after a day sail. After having rowed into the berth, I said the hell with sailing until the next day, when I replaced the plug and the engine fired right up. Unfortunately, I cross threaded the plug and screwed up the cylinder head. The plug that fouled was not stock, so I accused the mechanic of installing a cold plug. He told me it was a hot plug, and I had mixed my gas wrong. I said no way, since I had been mixing 2 stroke gas for over 20 years. Well he replaced the head, and I put that motor in the garage (I have 2), firing it up every 2 weeks.
    4 starts later, the plug fouled. WTF! The recommended plug was in there - maybe the mechanic had a point.
    So the question is what is a 50 to one mix? It consists of one ounce of oil to fifty of gas i.e. about 2.5 oz oil per gallon. However, I had an unopened bottle of Quicksilver brand outboard motor and an open bottle of West Marine"s oil on which I couldn't read the label. The Quicksilver label says for 50 to one, mix 3 oz per gallon. I followed the instructions and mixed 3 oz of West's oil into my gas and wound up with 2 fouled plugs. So, if you have a 2 stroke, be aware. The mechanic was right and I owe him an apology. 50 to 1 is 50 to 1 and I won't be using the Quicksilver brand again. Furthermore, if I seem confused, it's probably because I used to have a 100 to 1 mix Johnson.

    The 6 hp 4-stroke is a large as the space allows. And, 6 hp is adequate. Did you read the Outboard Discussions thread above?

    As bill said, the outboard motor thread has a lot good info. The 9.9 four strokes don't fit without some serious modification. Even if they did fit, you don't want one due to the weight.... These boats really squat by the stern with anything more the 50 or 60 pounds in the stern....

    I did look at the search box, but was hoping a new small 4 stroke was out there. I'll look at the 6hp long shaft by merc Does the motor work with a good wind?

    See the discussion about wind & tide with the 6 hp in the Outboard thread

    You might want to check with Amber Marine in Costa Mesa. He has an inventory of reconditioned 2 stroke motors. He sold me an "85 Evinrude 6 which runs like a clock.

    The 6 pitch prop on my 6 HP Nissan works fine. It'll push my Ariel at 3 knots into a 20 knot wind (with ocean swells).

    P.S. Be careful with that 15 HP engine. It's about twice the power you need for anything but head on steaming into a gale. If you run it full throttle in calm conditions, keep an eye on the stern, and when the stern becomes submerged to the point your backstay chainplate is in the water, back off on the power. I suppose it's self limiting to the extent that the outboard powerhead will become submerged and the engine will aspirate water before you sink the boat.

    You can't beat that price! And it'll be happy running well below full throttle.

    Two-Stroke Vessel Engines
    Facts About Two-Stroke Vessel Engines

    Two-stroke engines are not "banned" for use on all waterways in California, nor is there any plan to do so.
    Carbureted and electronic-injection two-stroke engines are considered high-emission engines. Generally, these engines were manufactured prior to 1999.
    A carburated two-stroke engine can emit up to 25-30% of its fuel unburned into the water or atmosphere, which is why high-emission engines are prohibited on some lakes.
    There is no salt-water or river restrictions in California on high-emission two-stroke engines, excluding personal watercraft (vessels such as Jet Skies) bans in some aereas. For example, San Francisco has prohibited personal watrecfart within 1200 feet of its shoreline. See "Local Restrictions" on our web page for a list of lakes.
    Direct injection two-stroke engines, made since 1999, are considered clean emission engines and can be used on every body of water in California, with some exceptions not related to emission limits.
    A new direct injection two-stroke engine will normally have a label sticker (with 1 to 3 stars) on its engine cover indicating that it meets California Air Resources Board emission regulations for 2001, 2004, and 2008 for vessel engine manufacture.
