Motors are Ruined by Negligence

Most Boats & Motors are Ruined by Negligence

I am sure that I will go unchallenged in the above statement. I am not sure whether many of these owners are so absolutely blind as to what they have done or not done, or if he is just lazy, or maybe a combination of things. Here we could probably also include things the owner did in his wisdom of trying to maintain/repair the motor & claim he was trying to help things.

The same applies to many things that the average owner of about anything mechanical, like fishing reels, guns, lawnmowers, etc. where at least some maintenance should be performed. And let's face it, there are a few persons out there that should just not be put in charge of boats or motors, or even a pencil sharpener for that matter.

A saying about boats that makes a lot of sense is, "The first owner takes it in the shorts when he sells the boat, second owner spends his money getting it into fishing shape, & third owner enjoys the benefits of the previous 2".

Quite a proper name "Temporary Insanity II"	Oh Darn, does this mean we will miss the hot bite?

Boats :
(1) Here in most areas, unless for the diehard fisherman, boating is a seasonal thing. So the boat may only be used for 3 months of the year, & then only part time. It will be forgotten the rest of the time. This down time is where a problem of deterioration will occur. Many boat owners do not have any idea of what is needed, so they take the boat to a marine repair shop to have it "winterized". If you are one of these persons, you are upping your odds in maintaining your fishing/boating machine. If you just park it outside in the weather when the season is over with, it may very well not want to start next spring. Plus the convertible top & seat covers deteriorate rapidly in the weather. And mice may like you for supplying a winter home.

(2) The shifting & throttle controls need to be inspected at the motor end & lubricated occasionally. Also be sure there are no sharp bends in these cables.

(3) Steering system also needs to be inspected & lubricated more than occasionally. This is especially so at the motor also. There are 2 types of steering, with the gear type push/pull cable from the steering wheel to the motor being the most common. The hydraulic steering is used more on boats over 20' & it uses a built in gear pump on the steering wheel unit that has 2 hoses to a hydraulic cylinder at the motor end. This unit will have to be watched to see if there is no leakage of oil anywhere in the system & seals replaced if need be along with the oil reservoir topped off.

Both of these need to have shaft seals & grease fittings at the motor that are maintained otherwise water may cause corrosion at the motor connection creating hard steering or breakage of something if you pull too hard on the steering wheel if it is frozen.

(4) If it is a cabin boat of any kind, you may need to place a small electric heater inside the cabin during the winter to minimize the effects of mildew.

(5) It may be best to remove your electronics from the boat if you store it for any time & store them in a garage or the house. (a) It lessens the chance of someone stealing them. (b) It will ensure that they do not get damp & possibly have internal shorts in the wiring when you need them the next time. (c) This would also apply to your nautical charts, as most of them are not waterproof & can draw moisture & mildew. (d) If there was some problem the last time you used the depthfinder, radio, or GPS, now is the time to send it to the factory for repairs.

(6) If it has a convertible top, after the season is over you should spray the snaps with WD-40 or Vaseline to lubricate the inner spring that snaps over the stud to hold the top in place. If you do not, later when you want to remove the top, the snap may become more than just slightly resisting. This can be especially bad if you boat in salt water & get a spray on the vinyl top. Repeated forcing may damage the top & tear the snap loose.

Outboard Motors :
(1) It will be hard to put the first few in actual order. But reading the owners manual, would probably be one of the top items, as they usually list many items that need attention.

This motor was for sale, is seized up & who knows what else

(2) IF the motor is used in saltwater, the failure to run it SOON afterwards flushing with muffs on to wash out as much as possible any saltwater left internally in the motor. This also applies to externally, in that the motor needs to be rinsed off to help protect the bolts / nuts & any of the metal linkage parts & brackets. Also the motor cowling should be removed & the engine itself rinsed off. Maybe it did not get dripping wet internally by a wave that came over the stern, but just being in the salt air has an effect over time.

(3) Remove tangled fishing line that may have gotten wound around the prop. OK, you can't see any so the 100' that you lost must have fallen off on your drive home. Guess again. Or you picked up some that the other guy threw away. The line, either monofilament or the newer spectra type braided lines WILL do damage to the prop shaft seals if left there long enough. The mono will melt from heat by being wound tighter on the shaft between a seal & the prop hub. This will then eat the seal out. Spectra line is worse in that it will CUT the seal & shaft rather quickly.

Either way if left long enough, the seal will be damaged, allowing the gearcase oil to leak out. When the oil is all gone, & the seal is ruined, water will leak in & all the internal bearings, shafts & gears WILL become damaged to the point that at some point in time your motor's lower unit will not function. It may not shift & will possibly seize up, because of the now bad bearings, gears & shafts. If left for a considerable length of time, the complete lower unit may become cracked because of the rust/corrosion & you can not even be able to take it apart without ruining the housing.

(4) If your fuel tank is removable, it is recommended that you transfer this left over fuel into a vehicle & use it up that way if you expect extended periods of down time. Or add a fuel enhancer/stabilizer additive to combat the fuel from becoming stale or if it happens to be an Ethanol blend to prevent the Ethanol from separating from the gasoline. If you have a permanent mounted fuel tank, add a fuel stabilizer & fill the tank full would be preferable. By filling it up, you lessen the chance of condensation inside the tank, which next spring will save time & energy if you don't do it & have water in the tank.

(5) Pull the drain plug on the lower unit & check for contaminated oil in the gearbox. If everything is OK, then top it off with new oil.

(6) If you are going to let it set for an extended period of time, you may want to winterize it by running it & spraying in the carburetor a "Fogging Oil" until it dies, then spray some more into the spark plug holes. This leaves a oily coating internally in the motor, which can extend it's life as compared to starting up a motor in 8 months that has become dry inside & possibly damaging the crankshaft or cylinder walls.

If you get an old motor given to you, the chances are very high that it will cost you way more than if you just went out and purchased a running motor. OK, it has just set for many years but you do not know the condition it was in at the time it was initially put away. You may luck out occasionally, but believe me most of the time, the motor is so old that no parts are available anymore or if they are the replacement price is prohibitive. Also if you are going to do the repairs yourself, are you good enough to do ALL the troubleshooting before you get into it & have already laid out money for something that possibly never ran right from the start.
