2-Stroke Restrictions

[Vwjay]

Ordered a Bizer chart to try to familiarize myself with the area before the trip. I believe I'm staying on Mark Island. Will be nice to know what's around and where the problem areas are beforehand.

I'm really not much into boating but haven't they stopped selling two stroke motors? Thought I heard they were phasing out their usage but that would be over a good number of years because so many people owned them or something like that?

Evinrude Etec outboards are two stroke and widely available. Old fashioned two strokes are hard to find because they produce too many emissions to be legal, but the law only states the allowable emissions, not the required technology to meet the standards. Evinrude figured out how to make them run cleanly despite being two strokes.

So there's no restrictions on using a 25 yr old two stroke is there?

Nope. That motor is so under-stressed that it will typically last forever too.

don't forget to get familiar with the unique hazard marking system in NH.
basically go north an east of a white with black top and south and west of a white with red top marker. Solid black and red markers indicate a channel so you go between them. A white/black near a white/red is not a channel so you go around both of them. You must also go no wake speed if you're within 150ft of basically anything.

There's a guy in craigslist.nh in Allenstown who sells old Johnson and Evinrude outboards for aprox $250-750, size 2-10-hp., 1955-1974 He has about 30 different motors in stock, and he replaces the needed parts with new parts made by OMC.

His name is either Johnny Johnson, or Dr. Evinrude ...... cannot remember?

Just go to craigslist.nh, boats, and do a search for Allenstown to see photos. For $300, I got a 1967 Johnson 3 1/2-hp 20" shaft for a sailboat, and it beats the pants off a 2015 Honda 3 1/2-hp four stroke. OIl ration is 25:1, and it runs great on blue Wal-Mart 2-stroke Tech oil for $3.94/quart which will easily last all summer.

Old 2-strokes can last forever if they were made by OMC.

Probably, if he sold these in California, he would go to jail ...... but here in New Hampshire, it's a different story ..... Live Free or Die! What the heck.....even the NH Marine Patrol runs with 200-hp two-strokes?

Just for clarity, there's a big difference between older 2 strokes (carbureted or fuel injected) and the newer 2 stroke engines. Mercury uses a low pressure air injection in their Optimax engines (these are what the Marine Patrol runs on several of their patrol boats), Tohatsu has a similar LPDI system for some of their engines. Yamaha had several high pressure direct injected two stroke engines in production a few years ago, not sure if they still manufacture these. Evinrude E-Tec engines are all high pressure direct injected and are EPA 3 star rated for emissions which is equivalent to or better than ratings for 4 stroke engines (depending on size and manufacturer). The "new tech" 2 strokes are typically significantly lighter than the same HP engine in a 4 stroke. Weight can be a big factor especially when trying to repower an older boat so it's good that "new tech" 2 strokes are available.

Any of the newer 2 strokes mentioned above have almost zero smoke / odor, nothing like the old school engines. I had a Mercury 115 "tower of power' back in the day, on a cold start it looked like the boat was on fire!

Even my older(2004) Yamaha pwc had oil injection and never smoked.
