  1. SkiDoo fire hazard recall

    There's a safety recall on several 2017-2018 SkiDoo sleds with the 850 E-TEC engine due to a fire hazard. https://www.cpsc.gov/Recalls/2019/brp-expands-recall-of-snowmobiles-due-to-fuel-leak-and-fire-hazard-recall-alert
  2. Snowmobile exhaust systems

    What I'm suggesting is that the new regs simplify the measuring process, I'm not saying that there isn't a good deal of discretion in the stop. The old regs called for a measurement process that wasn't possible in the field.
  3. Snowmobile exhaust systems

    The first part of the new reg would seem to include all snowmobiles, including vintage: No person shall sell, offer to sell, or operate in this state a snowmobile which produces total vehicle noise of more than 82 decibels sound pressure on the "A" scale as measured using the Society of Automotive Engineers (SAE) J2567 standard. Back in the 1975 the regs called for a max of no more than 78 dB(A) from a distance of 50 feet while traveling at full throttle when tested under the Society of Automotive Engineers (SAE) J192 procedures. The new regs max of 82 db uses SAE J2567 which measures noise while the sled is stationary and at 4000 rpm and the microphone about 13 feet from the sled.This standard seems designed to simplify the work of law enforcement in measuring sound after a stop. Here's something from the IASA: http://www.snowiasa.org/wp-content/uploads/2015/06/2015-IASA-Sound-Test-Presentation.pdf 6.0 Procedure 6.1 The snowmobile shall be parked at the test site with an operator seated in the normal operating position, and the forward traveling path of the snowmobile clear of obstructions as required in 5.1. 6.2 The brake shall be set throughout the test. 6.3 The engine shall be started and run until reaching normal operating temperature range, as specified by the manufacturer. 6.4 The operator shall slowly open the throttle until a steady 4 000 rpm ± 250 rpm engine speed is achieved, while holding the snowmobile stationary by applying the brakes. 7. Measurements 7.1 The sound level meter shall be set for A-weighting network and slow dynamic response. 7.2 The sound level meter shall be calibrated and adjusted, if necessary, so that the meter reads within 0.1 dB of the true level at the microphone. 7.3 The microphone shall be located on the side of the snowmobile towards which the exhaust outlet(s) is (are) directed. This is generally on the right side. The longitudinal axis of the microphone shall be in a plane parallel to the ground plane. There shall be no physical attachment between the snowmobile and the microphone/sound level meter. 7.4 The microphone shall be located at a distance of 4.00 m / 157.5 in from the longitudinal plane of symmetry and 1.22 m / 48.0 in above the ground plane in line with the exhaust outlet. If there is more than one exhaust outlet. I'd guess that a lot of the real old stuff won't pass the 82 db limit, but we won't know until tests are done on the trail.
  4. Snowmobile exhaust systems

    HB 591 has been signed into law, and some changes were made to the snowmobiles rules around exhaust systems. It appears that a different SAE standard will be used, and all sleds must comply with that standard. No person shall sell, offer to sell, or operate in this state a snowmobile which produces total vehicle noise of more than 82 decibels sound pressure on the "A" scale as measured using the Society of Automotive Engineers (SAE) J2567 standard. No person shall modify any snowmobile in any manner that shall amplify or otherwise increase total vehicle noise above that emitted by the snowmobile as originally manufactured with the original muffler nor shall any person operate any such snowmobile. The provisions of this paragraph shall not apply to snowmobiles operated at permitted snowmobile events as defined in the department's administrative rules, FIS 1501.01(d). No person shall operate a snowmobile manufactured after February 1, 2007 that does not display on its exhaust system's critical components the letters “SSCC Certified,” a visible and unaltered certification marking issued by an independent organization, the Snowmobile Safety and Certification Committee (SSCC), that certifies snowmobiles for uniformity of safety features and noise levels. The letters shall be legible and have a minimum height of 4 millimeters. The marking shall be on the exhaust silencer, visible and legible to an observer by lifting a snowmobile hood and without detaching or dismantling any component parts. The markings shall be embossed and pressed or attached in a similarly durable manner to the outer surface of the exhaust silencer assembly, and shall be resistant to alteration. The markings shall be so affixed that it shall be difficult to remove, replace, or alter without detection.
  5. Free- Polaris speedometer

    While cleaning out the cellar I came across a speedometer from a Polaris Indy or TX. It's about 3¼" round. I tested it with an electric drill and it works, and it looks OK. Update: Just found the tachometer for the same sled. I'm leaning towards the sled being a TX. Didn't test the tach.

  7. Something to think about

    The damage to the rental sled would be capped at the cost to replace the sled (maybe $10,000?) The cost of a liability claim by someone you injured/killed, or property damage, through negligence doesn't have such a cap. I suspect that most people don't get the answer to these questions until after they have an accident.
  8. No new posts since 3/21/19

    Might be because your average sled rider has moved on. The die-hards may trailer to Pittsburg, but most will call it a day. Boating and ATV sites should be heating up.
  9. Off Topic

    The insurance company is claiming the guy drove the vehicle in an unsafe and negligent manner and wants the money they gave the owner back from the guy. In New Hampshire, the uninsured motorist portion covers only medical expenses. The driver was from Mass, so I'd assume he had insurance, but does that cover a borrowed car? In most cases the insurance follows the car not the driver, although most auto insurance will cover a rental car. For the guys sake I hope he has personal liability insurance in his homeowner's policy along with an umbrella policy. Like I said about #1......
  10. Off Topic

    I'm calling this off topic, but there is some connection between sleds and trucks and trailers, so maybe it's not too far off base. Back in 2017 a guy wanted to buy a 2013 F-150 Ford pickup in a private sale from a woman in Laconia. He got permission to test drive the truck and as part of the test towed his boat/trailer to Paugus Bay and attempted a launch. The launch didn't go well when he exited the truck with the transmission in reverse while launching, and boat, trailer, and the Ford ended up in Lake Winnpesaukee. The owner filed a claim with her insurance company and it was settled for $30,691.49 to cover damages. In March of this year the insurance company sued the guy who sank the Ford to recover the money they paid the truck owner. I'm sure there are lessons to be learned here. 1. Have a very good insurance company and agent. 2. Letting an unattended prospective buyer in a private sale test drive a vehicle is a bit risky. 3. Letting a prospective buyer use your vehicle to transport and launch a boat is riskier. 4. See #1 I guess you could substitute snowmobile for boat. I'd also guess that any long term insurance agent could tell a similar story. Full story. I wonder if the woman still has the same insurance company?
  11. Something to think about

    Over the weekend there were two separate snowmobile accidents in Gorham involving a sled hitting a tree. The sled operators were middle-aged women from Maryland and Florida, and both were wearing helmets but lacked experience. I'd guess that one or both of these accidents involved a borrowed or rental sled. Union Leader GORHAM — A Florida woman was injured Saturday when she lost control of a snowmobile and struck a tree, the New Hampshire Fish and Game Department said. Christina Coleman, 49, of Juno Beach, Fla., crashed around 6 p.m. Saturday on Bear Spring Trail, Fish and Game said in a news release. Coleman’s son, who was riding with her, assisted her back to the trail and called for help, the news release said. Coleman, who was wearing a helmet, was taken to Androscoggin Valley Hospital for further evaluation and treatment, according to the news release. Investigators said inexperience was considered the primary cause of the crash. GORHAM, N.H. — A woman was seriously hurt in a snowmobile crash in Gorham on Sunday. At 5:25 p.m., Inna Getsin, 37, of Owings Falls, Maryland, struck a tree when she lost control while navigating a turn on Bear Spring Trail. Getsin was thrown from the snowmobile but was able to get herself back on the trail. Members of her riding party came to her aid and called 911. Getsin was transported by ambulance to Androscoggin Valley Hospital in Berlin for further evaluation and treatment. Getsin was wearing a helmet. Inexperience is considered the primary cause of the crash.
  12. Something to think about

    I'd guess that the rental company offers insurance protection at an extra cost, but probably has some sort of liability coverage to protect themselves.. Still, if rental sleds are involved in a third of sled accidents somebody is paying for the damages.
  13. Something to think about

    In an earlier post about ride to Evans Notch I wrote about some folks on rental sleds we met while in the notch. I'd guess they were sled newbies. Today I saw this on the NHSA site. Snowmobile Rental Accidents Out of approximately 42,000+ registered snowmobiles in NH, only 318 are rental units Yet 32% of snowmobile accidents in the 2017/2018 season involved a rented snowmobile Inexperience was a contributing factor in all of those accidents Seems odd that less than 1% of the sleds were involved in 32% of the accidents. These rental sleds probably put on a lot more miles each year than most sleds, but even if the rentals put on double or triple the mileage it's still out of line. There's a parallel with teenage auto drivers: "according to research conducted by the AAA Foundation for Traffic Safety, 16- to 17-year old drivers are nine times more likely to be involved in a crash than adults and six times more likely to be involved in a fatal crash than adults." It's probably fair to say that a person who would operate a sled with minimal training and zero experience could be considered risk tolerant. High risk tolerance and inexperience, what could go wrong? I wonder what the insurance rates are for rental sleds?
  14. It worked for me. Nice work.
  15. ATVs on public roads issues

    The ATV ban bills failed in all three towns. http://www.colbsent.com/breakingnews.php As for the Colebrook "recreation trails supervisor" position, it died too. Metallak ATV Club president Craig Washburn opened discussion on Article 27, which proposed the Recreation Trails Supervisor position, by stating, "I'd like to know why the taxpayers are going to pay for something I've been doing 40 years for free." Julie Moran pointed out this person would be neutral and work as a mediator "so we can address the issues residents are angry about." Mr. Placy said the board views this as a move that would help the club, but Terry Rosi disagreed with the need for a $10,000 position. "I think this can be worked out between both sides with some transparency," he said. The measure failed, nullifying the next article that would have funded the position, and the 7 p.m. meeting adjourned at 10:55.
