1994 Johnson 150 HP Ocean Runner

[lundboat]

I have a couple questions. First, I am fairly new to the boating world and I just want to make sure I'm taking care of my equipment properly. My engine runs really well, my only problem with it is that the starter will sometimes stick in cold weather. Any advice for this problem? <br /><br />My general questions are:<br /><br />1. Do I need to be careful with the type of gas and Octane levels with my engine?<br /><br />2. What winterization is needed?<br /><br />3. Suggested care for saltwater use? Is flushing with garden hose enough?<br /><br />thanks.

Try a small amount of motor oil on the starter bendix shaft and insure your batteries are fully charged.A weak battery will show similar syptom.Battery voltage should not drop below 9 1/2 to 10 volts while cranking.<br />87 octane fuel is generally sufficient ,however you should follow what your owners manual recommends for your engine.<br />You can do a search on these forums for winterizing tips.Lots of info.<br /> A good flushing on hose and external rinse down of motor is usually sufficient.Some guys down south here that use their rigs exclusively in salt water coat the lower engine pan area with lps3 to inhibit corrosion.Install new waterpump at least every 2 years depending upon use .Insure your sacraficial anodes are well grounded and inspect every season.<br /> Oh , and don't forget the plug.

thanks for the information, I will make sure my batteries are in good condition and see if that fixes the problem. <br /><br />I applogize for the novice question but what are "sacraficial anodes"?<br /><br />thanks

lund-<br />they are also referred to as Zinc's. They are pieces of zinc that are attached to your outboard and are designed to corrode before your motor does. They work by corroding very readily and therefore using up the galvanic current that can corrode something you actually need (ex. motor parts). Good luck

They are the zinc plates that will be attached in various locations on lower unit of motor and transom brackets.They induce elctrical current that is generated in water (particularly salt water)and act as sacraficial metal for this corrosion to eat on instead of your engines lower leg and transom brackets.That is why it is important to assure they are in direct (continuity ) connection to the metal to which they are attached.This can be tested using a simple ohm meter reading between the zinc plate and case of motor.There are even additional optional ones available through your dealer or marine supply house for added protection.I've got every available one on my motor as it is exclusively used in salt water.

Thanks, I'll be sure to get some additional ones as well. I'm very protective of my boat and am happy to spend a few more bucks to ensure the engine will last a long time.<br /><br />The engine spends 90% of its time in fresh water but I want to make sure its protected.
