First outing.....questions

[7lazy77]

Well, got the "new" toon out for the first time & came across several things that I have questions on. Motor (115 HP Johnson) started right up, but on several occasions, the warning horn went off in short continuous beeps which indicated no oil flow from pump. I immediately shut the engine off for a while after it did this about three times. After having lunch & for the rest of the day, the warning horn on the motor didn't go off at all. What could of caused this? Could there have been air bubbles in the oil line that could of caused a shortage of oil supply? Please keep in mind that I hauled this boat over 500 miles home last week.
I was also wondering if I should have the crabs adjusted in the motor since there is quiet a bit of altitude change from where I live compared to where it came from?
There were 6 adults & 8 kids (all under the age of 9) on the toon & my top speed was around 15 mph, does this sound about right?

Thanks for the help, this is my first toon, so I am still learning the ropes.

Re: First outing.....questions

Tell us more about the toon;year of the motor, present altitude ,previous altitude.
wot rpm and speed?

My first recommendation is that you immediately switch over to a fuel using pre-mixed oil and gasoline at a ratio of 1:50 until you solve this problem. This will save you from destroying your motor by running it without oil while looking for the cause of the alarm.

The owner's manual of almost every outboard will contain information about how to interpret alarm signals.

In general I have found that the literature published by Johnson-Evinrude about their outboard motors is quite good, and it will explain in detail how your motor works and how to interpret any alarm conditions it gives you.

The alarm module is somewhat limited in its ability to pass information to the owner. It only has an aural signal. It modulates the cadence of the aural signal to indicate the function. There are only three possible cadences:

When the key is turned from OFF to ON, the alarm sounds a signal to verify that it is operating properly. This signal sounds like a Morse code letter D or B, i.e., "dah-didit" or "dah-dididit". If the module does not sound this signal it is malfunctioning.

After engine start, the alarm goes silent until there is an alarm condition.

If the engine temperature rises above the threshold of the thermal switch in the cylinder head, the switch closes. This causes a continuous tone alarm which persists until the temperature falls enough for the switch to open. This ends the alarm tone.

Any of the following conditions will signal a BEEP-BEEP-BEEP:

--oil level below the float switch level in the under-cowling reservoir

--input gear shaft to mixing pump turning too slow in relation to engine speed

There is no way to tell which of these events causes an alarm. You have to deduce which is the problem by inspecting the motor.

It is also possible that any of the following conditions will also signal a BEEP-BEEP-BEEP:

--defective float switch in the under cowling reservoir

--defective motion sensor in the mixing pump

--defective ignition module sending false signal

--defective alarm module creating false signal

If you want to diagnose this problem further, you will need to obtain the service manual for you engine. Thoroughly read the service manual. It will cover the oiling system and alarm system in detail. There are many complex interactions which can cause these alarms.

Problems with these alarm modules seem to be very common.

I took mine off the first month I got it and have pre-mixed since. No worries here.

Crabs do not need adjusted for altitude but should not be in your motor. Hope you and your crew enjoy tooning as much as we do.

+1 on doing away with the vro system. If it fails, it is catastrophic for your engine. Pre-mix your gas and oil and you will never have to worry about it again.
