Either way, simply plopping the boat in the water, starting your outboard(s), and then blasting out into the unknown isn’t really the best plan. In the interest of full-transparency, you’ll find that the tips in this post have a bent toward four-stroke outboards, but don’t click away just yet. Next, check the wiring, hoses, belts, and other one-engine components to make sure they’re in good shape, firmly attached (not loose or dangling), and free from corrosion or other damage. Spark plugs are less of a problem on outboards than they used to be (especially on four-stroke outboards), but that shouldn’t stop you from removing each one, inspecting it, and checking its gap, unless you did this during layup. Once you’ve inspected everything under the cowling, have a good look at the outside of the outboard all the way down to the lower unit. We’re going to assume (or hope) that you or your service pro changed your lower unit oil before layup. Unless you have X-ray vision, you won’t be able to check your cooling water impeller without removing the lower unit. Check the engine oil on your four-stroke outboard before starting it this spring, and if you didn’t change the oil and filter last fall, head to the marine supply shop on an oil change mission.
We also hope that you four-stroke outboard owners changed the engine oil and filter before you stored the engine for the winter. You should pay a lot of attention to the components in and around your lower unit such as the water intakes and zincs. Inspecting your fuel supply all the way from the engine to the fuel tank is a vital step in commissioning your outboard each spring.
The Company offers the details of this vessel in good faith but cannot guarantee or warrant the accuracy of this information nor warrant the condition of the vessel. A stylish sailing or casual jacket with a better fit and flexibility than the previous version. Musto have redesigned the shorter length Championship Buoyancy Aid with enhanced ergonomic for for the racing sailor. The WavEco 2.6M Slatted Floor Dinghy is incredibly lightweight and if you are a looking for a dinghy which has been designed for leisure use, then look no further. Provides 275 newtons inflated buoyancy which provides greater turning moment and higher floating position. The Lehr propane-powered outboards can run with a remote fuel tank or a screw-in one-pound camping bottle. Herzer is a circumnavigator and a licensed captain, but more importantly, he’s the CEO of Lehr, a manufacturer of four-stroke propane-powered outboards that debuted at the Miami International Boat Show this year. It took Herzer some time to get from the initial idea, inspired by the propane galley stove on a research ship, to the propane outboard. Outboards that can run on compressed natural gas have been around for a while, but they failed to catch on, because fueling was a hassle, to say the least, and they weren’t all that efficient, simply because they were originally conceived for gasoline consumption. Lehr published research numbers that indicate propane produces 25 percent less CO2 and up to 60 percent less CO, while reducing the emission of ultra-fine particulates by 97 percent. But Herzer is focusing on the benefits downstream, which should be music to boat owners’ ears. Lastly, propane is easy to package in exchangeable tanks that are common for gas barbecues, or in 16-ounce cartridges that are screwed into the back of the outboard, the same as they would be in a camping stove or gas lamp. Lehr outboards are priced between comparable common four-stroke gasoline engines and zero-emission electric outboards.
Good luck finding a marina on the water that refills 20 lbs or 30 lbs or larger propane tanks. The good news is that if you properly winterized your four-stroke outboard or your two-stroke outboard before you laid up the boat last fall, getting it going should take no more than 30 to 45 minutes.
Smart boaters do a thorough check and test run long before that first fine day of warm boating weather hits.

The only real differences between most two-stroke outboards and four-stroke outboards are that two strokes are generally a little less complex, and there’s no engine oil to worry about.
First, look for possible pest (mice, rats, squirrels) infestation and wire-chewing activities.
Make sure you follow your manufacturer’s specific instructions for spark plug removal and installation, and also for gapping. Here you’ll check for corrosion, dents, or other damage, especially around the propeller and lower unit area. It’s not only an extremely inexpensive way to keep your lower unit humming along; it’s also a great way to ensure you’re starting the season with a full load of fresh gear oil. Like everything else, if it’s been ages since you or a pro replaced it, now is a great time to slap a new one in. If you didn’t (or again, can’t remember when the last time you did was), head down to your marine supply shop, pick up the right oil and filters for your particular model, and swap out the old oil and filters for new, according to the manufacturer’s recommendations. Again, if it’s been so long you can’t remember, or the one that’s there is from last season is dirty, replace it.
While the engine is running, continually check those muffs or other connections to make sure your engine is getting sufficient cooling water.
Follow the recommended starting procedures for your particular model, and then allow the engine to run, in gear and at idle for 10-15 minutes, checking for any signs of leaks, cooling problems, or other issues. While we can’t promise that you’re motor doesn’t have any hijinks planned for you this year, starting off on the right foot will go a long way toward providing a blissful boating season. A buyer should instruct his agents, or his surveyors, to investigate such details as the buyer desires validated.

These engines look and act much like the conventional outboards already familiar to boaters, and use a widely available fuel.
It burns cleaner, it’s cheaper, it has high energy density, it’s readily available, and the US won’t have to import it from hostile regimes.
On the way, he took a detour developing and licensing this technology for lawn-care equipment, scooters, and go-carts. According to the company, propane also has 96 percent fewer carcinogenic emissions than gasoline and zero ozone-depleting potential. While there are many benefits to propane as a fuel, sourcing it as a byproduct of crude oil extraction remains ecologically problematic.
Besides more benign emissions, propane-powered engines require less maintenance and fewer oil changes.
These receptacles are lighter than batteries or the thick-walled tanks that are needed for compressed natural gas, because propane liquefies at much lower pressure. For those further afield, we can market the vessel and ensure the correct paperwork is completed allowing the purchaser to buy with confidence but with the vendor doing the viewing. The bad news is if you didn’t winterize it, you’ve likely got a long weekend or a costly visit to your marine service center ahead of you to catch up on preventative maintenance tasks. While you may be laughing at the moment, you’d be surprised how many outboards are used as temporary housing during winter storage. Check hoses for cracks and broken hose clamps, and make sure all wire ends are securely attached to their termination points.
Replace any external zincs that are corroded beyond two-thirds of their original size, and repair (or have repaired) any damage you’ve noted on the lower half of the outboard itself. If you’re not sure whether you did, didn’t, or can’t remember the last time you did, now’s a good time to drain your lower unit oil and refill it according to your manufacturer’s recommendations.

If you’re interested in how to perform the procedure (or are just curious), check out this video on how to do it yourself. If you did, give your oil level a check to make sure that nothing leaked out over the winter. If you’ve got a larger Yamaha outboard, here are some tips on changing the on- and off-engine fuel filters. If you are using an external tank, check the outside for leaks, cracks, or any other damage. You’ll also usually find plenty of Zerk (grease) nipples in the trim and tilt area as well as around the steering mechanicals. Old, dirty oil has corrosives that will eat at your engine’s innards over the winter.
As long as we are drilling for oil, we’ll get (relatively) cheap propane, which could power leaf blowers and outboards. According to Lehr, a gallon of propane can power a 5-hp outboard for up to two hours and the 2.5-hp model for up to four hours, depending on operator habits and sea state.
Your small four-stroke outboard has spring commissioning needs similar to those of a larger one. Many four-stroke outboards also have internal pencil zincs that require changing periodically; check those, too, while you’ve got zincs on the brain.
While you’re down here, check the cooling water intakes for debris or any winter stowaways, such as stinkbugs or other insects.
Like the lower unit oil, keeping fresh engine oil in your four-stroke outboard is cheap insurance for long outboard life. There are tons of onboard fuel filters in today’s big modern four strokes, so if your outboard hasn’t seen any filter love in a while, it’s probably not a bad idea to get it up-to-date on its service schedule now. You can also check out this video on troubleshooting an outboard motor that will not start.
Since I live up north, it is also already time to start getting it ready to store for winter. The average residential price for a gallon of propane was $2.87 in March 2012, a buck less than most people paid for a gallon of regular unleaded. Today, Lehr holds numerous patents and was recognized with the EPA Clean Air Excellence Award and the Popular Mechanics Breakthrough Product Award.
At the same time it is a substitute for water in the controversial method of hydraulic fracturing (aka fracking) to get oil out of underground shale deposits.
To combat these problems, boaters are required to treat their fuel with more additives, which adds cost and complexity. The motors are offered with a three-year limited warranty and are sold by distributors such as Donovan’s and retailers such as West Marine.
The average wholesale propane price decreased by almost 8 cents per gallon to $1.24 per gallon, according to data by the US Energy Information Administration.
Replace any sections of fuel line that are cracked, worn, or damaged, and replace rusty or damaged hose clamps, too. Bernardo Herzer is putting before consumers, because he is convinced that a cleaner and more affordable energy future won’t happen without gaseous fuels.
