Today one of the most common problems with engine performance is fuel related. Add stabilizer to every tank of gas and run it as per the instructions on the bottle for storage use. The new Ethanol stabil is BLUE in color and can be purchased at Wal Mart. Also add a little 2stroke engine oil to every tank of gas, This will help aid in keeping the anti siphon valves from sticking in the fuel tank due to the Ethanol. Today's fuels are starting the varnish process within just a few days . Today's fuel is recommended to be used within 3 weeks. Yes that is right the fuel is only good for 3 WEEKS. Replace fuel filters regularly and purchase gas where the stations have a high volume of use. Also pay close attention at the pump for fuels containing Ethanol Better known as E10 or E15. Ethanol creates water in your fuel better known as Phase Separation, and will cause poor running conditions and or the engine won't run at all.
Replace fuel seperator filters every 3 to 4 months wether the boat is in use or not, This is very important due to the ethanol in the fuel. What I am finding is the Ethanol is deteriorating the paper elements inside the fuel filters and it is clogging jets and fuel pumps. If your boat doesn't a Water seperator filter I would highly recommend you having one installed .
I have been made aware the Government just passed the law for fuel manufacturers to start with 15% Ethanol. This is only going to create more problems for us boaters.
I have noticed this Ethanol problem seems to be more pronounced in boats that sit on a lift or in the water. What happens is the ethanol is heavier than Gas so it settles to the bottom of the tank. When you start and run your engine the first thing it gets is a shot of Ethanol instead of gas. Boats that get trailered to the ramp are having less problems with the fuel because the Ethanol has time to get mixed back into the gas.
Before you go fishing-Boating shake your boat well to mix the Gas a bit before you start your engine.
Another thing I am finding is, due to the Poor Quality of fuels we are buying, the fuel has a low flash point causing engines to foul spark plugs. Try to stay away from extended Idle time. What I am finding is if the engines are Idled alot the Spark Plugs are fouling due to the low flash points in the poor qualities of fuels. This is happening in 2 and 4st engines but seems to be more pronounced in the 4st engines. To Explain... Outboard engines do not develop the same temperatures inside the combustion chambers as a car. At Idle the combustion temperatures are low thus causing the spark plugs to load up with fuel causing them to Foul.
Now also keeping up with your engines cooling system is very important. All engine manufacturers recommend if you run your engine in Brackish or Mineral laden water you should replace your water pump annually or every 100hrs. It is a smart decision to replace your thermostats at the same time. This is essential because if a Thermostat is sticking partially open this will cause the engine to run too cool also resulting in the engine fouling the spark plugs and could potentially cause internal damage to the engine.
Battery connections is a very important issue with today's high tech engines. If your connections are loose this will cause a surge in voltage. This voltage surge can cause damage to the computer (EMM) on your engine costing you a large amount of money. Make sure the connections are clean and tight, (Tighten them with pliers.) Also while you are at the battery check the fluid level in the battery and add water as needed. (Distilled water only)
Mono fishing line is the #1 killer of engine lower units, Remove your prop regularly and check the shaft for mono wrapped around the propshaft behind the thrust washer. Check the prop manufacturers specs for correct torque and add a good water proof grease to the splines on the shaft. and always replace the cotter pin.
Corrosion X is a boaters best friend, This stuff is good for all applications. After a day of fishing-boating rinse all components like steering, jackplate etc.. with fresh water and spray a liberal amount on all moving parts. I like to call this stuff liquid mechanic. You may also use it on your fishing reels and also on all electrical connections like switches and fuse panels.
For a degreaser WD40 works well to remove grease stains and oily finger prints.
This is good for care of stainless steel handrails and other stainless parts. Clean with fresh water then a simple sponge with the scrub side will polish the rust stains then apply a liberal amount of either WD40 or Corrosion X This will aid in keeping rust stains down. If stainless parts rust a bit, this is good because if parts were made of only stainless it would be very week so rust tells you the stainless has some steel in it to give it strength.
As far as outboard oils for 2stroke motors, use only a manufacture brand oil.
Oil blends do not mix and if you need to add something other than name brand oil, run the oil tank down as low as possible before adding another oil type. What happens is different oil blends mixed into your oil tank will congeal causing the pump to NOT pump oil thus burning up the engine due to lack of lubrication.
By all means read your owners manual on your motor and stick with the oil the manufacturer recommends for the type of engine you have. Some engines require a special oil to be run in the engine and by not running that oil will shorten the life of your engine and Void any warrantee.
Please remember I am The owner and operator of this business, Meaning I am the one who will work on your boat. I try my best to not get a back log and to try to fix your boat as promptly as possible. Also because I work on a lot of boats in canals I do not carry my phone with me at all time. If you call Please leave me a detailed message and I will get back to you as soon as I can.
As always if you have a question with your boat Call, Text or email me and I will help in any way I can.
I Appreciate your Business!

Water pump impellers are not centered in their housing, by design. This means that the rubber blades on one side are being bent over more than those on the other side. The expansion and contraction of these blades inside the cup draw water in and push it out, creating water pressure. With normal regular use, these blades remain supple and capable of working effectively. However, lack of use will cause the blades on the impeller to dry out and develop "muscle memory", where they won't fully flex as intended. This causes a loss of water pressure and can result in broken blades if they're dry enough. Therefore, it's important to replace the impeller according to your outboard manufacturer's schedule.
