Outboard Motor Oil

Two cycle oil for high-performance racing motors needs to contain a heavier synthetic base than most to protect the pistons and bearing that are under more strain from the rigors of racing.  High performance two cycle motors can include stock or modified motors, including snowmobiles, personal watercraft, Moto X motorcycles, ATVs, go-carts and certain outboard motors. 

Performance motor oils need to reduce friction and burn clean, because high performance two cycle motors run hotter than recreational outboard motors.   The properties of appropriate performance motor oil will also provide some protection against wearing of essential engine components.

Don’t let the gloom and doom predictions of high gas prices keep you from your boating passion. Even with bulk oil costs soaring, it’s still possible to have some money in your pocket when you leave the fuel pier. By understanding your boat’s design - whether it has a displacement, semi-displacement, or planning hull - and doing some easy calculations, you will know the boat’s most economical cruising speed.

Displacement and Semi-Displacement Boats
Displacement hulls are designed to force their way through the water. A semi-displacement hull achieves a partial plane, which reduces drag and wave making. Both have a top speed that cannot be exceeded without increasing the power significantly. A large power increase also means greater fuel consumption.

To figure the maximum speed, multiply the square root of the waterline in feet times 1.34. Using this calculation for a 38 ft. displacement hull boat, the maximum speed is 9.2 knots. To save money on gas with a displacement or semi-displacement hull, do not try to increase your speed past the calculated maximum speed. In the case of the displacement hull, increasing power to go faster will use more fuel without a resulting speed gain. With a semi-displacement hull, your speed will increase, but there will be a corresponding fuel consumption increase.

Planing Boats
Pull back on the throttles with a true planing hull. Fuel consumption increases with every knot while the boat is on plane. A boat with a planing hull has the greatest fuel economy at the point when it first comes onto plane, or begins to skim the surface of the water.

Limiting the amount of time a planing boat displaces water before coming onto plane will also result in reduced fuel costs. This doesn’t mean slam the throttle downs to get up on plane faster. Instead, bring the boat up to speed at a moderately quick, steady pace.

If you are like me, you like to go fast quickly. But, if you follow these tips for reduced fuel consumption, you will finish at the end of the boating season having won the fuel marathon with a few extra dollars in your pocket.

As mentioned in an earlier post, the summer boating season is ready to start and you’ll no doubt have filled your boat with marine engine oil and anticipation to hit the waters.  Here are some safety tips to keep in mind before you take her out on the water:

• Be weather wise. Sudden wind shifts, lightning flashes and choppy water all can mean a storm is brewing. Bring a portable radio to check weather reports.

• Bring extra gear you may need; a flashlight, extra batteries, matches, a map of where you are, flares, sun tan lotion, first aid kit, and extra sunglasses. Put those that need to be protected in a watertight pouch or a container that floats.

• Tell someone where you’re going, who is with you, and how long you’ll be away. Then check your boat, equipment, boat balance, engine and fuel supply before leaving.

• Learn to swim. The best thing anyone can do to stay safe in and around the water is to learn to swim. This includes anyone participating in any boating activity.

• Alcohol and boating don’t mix. Alcohol impairs your judgment, balance, and coordination — over 50 percent of drownings result from boating incidents involving alcohol. For the same reasons it is dangerous to operate an automobile while under the influence of alcohol, people should not operate a boat while drinking alcohol.

In addition to cleaning your boat and changing out your outboard motor oil, there are some other little things you can do to prepare for a summer of taking your vessel out on the water.

• Update your first aid kit

• Make sure lifejackets are in working order

• Replace batteries on GPS

• Inspect engine

• Make sure you have a cell phone charger for your boat

Step 1:
Clean the bottom of your boat. Plant and barnacle buildup causes extra friction that burns additional fuel.

Step 2:
Remove excess weight from your boat. If you have a lot of heavy objects in the boat that you do not regularly use, simply remove them. This can account for as much as a 2 percent reduction in miles per gallon.

“Bess Cary loved ice cream. One day, during a picnic on an island in a Wisconsin lake, Cary asked fiance Ole Evinrude if he would row back to shore to get her a dish.

And Evinrude outboard 2 cycle motors were born, and with them a long history of reliability and non-stop innovation.  In the market of 2 cycle outboard engine oil Evinrude continues to lead with both its Evinrude XD 50 and XD 100 oil types for all kinds of 2 cycle engines.  See for yourself how to increase your outboard motor’s performance with near half-off oil prices at domo-online!

BRP Australia

Sydney Australia, February, 2007 – The Southern 80 Ski Race which has been held for over 40 years was again held this past weekend. The Race takes place on the Murray River between Torrumbarry and Echuca on the second Sunday in February each year.

The event is a two up water ski race, which covers the river from Torrumbarry to Echuca with over 120 bends on this 80 kilometer race section. The race attracted 563 entries from all over Australia with international representation from New Zealand, Great Britain and the USA.

Once again Evinrude E-Tec has shown a clear set of heels in the MOC and SMOC classes with 5 races contested, winning all 5 and obliterating 3 long standing Mercury records with the winning SMOC class boats, all powered by fully homologated
Evinrude E-TEC™ 250 H.O. and Evinrude Outboard Motor Oil!

• SMOC Expert class Stalker Racing broke the 2004 race record.
• SMOC Social Class Stalker Racing broke the 2003 Mercury race record.
• SMOC Short Course Expert Evinrude Racing broke the 2007 Mercury race record.
