Re: eska 7 hp just died and won't start? help
i have a eska 7hp 1747 d outboard was running fine for the last few trips, then all of a sudden the gas cap started popping off, then it died. won't start or even try to start now. was the simplest thing too start before this. any suggestions
An observation: "Gas cap popping off" would make Sheerluck Holmes pull his hair out if that was the only clue he was given!
But we'll make some assumptions and attempt a Holmsian solution:
Assuming the gas tank referred to in the indictment is the on-board tank the only thing that would make it 'pop off' would be increased internal pressure.
But what could cause increased pressure?
Two things would be required:
1. Vent hole in gas cap not opened or stopped up.
2. Additional heat load in the tank.
The less said about the former the better!
What might cause the latter?
An overheated engine cylinder immediately below the tank springs to mind as the most logical assumption.
"But what would cause that" you ask.
Only insufficient cooling CAN cause it! It's hardly reasonable to think that even the dim-witted or deaf would fail to note that the flywheel had suddenly and catastrophically shed all the cooling fins so we're left with only a single conclusion acceptable to the reasonable mind----the waterpump failed.
If so and it was ran long enough without sufficient cooling to cause internal pressure build-up from excessive heat load to cause the gas cap to 'blow off' then the logical mind assumes some measure of internal damage. The fact that a previously amenable engine will no longer run exacerbates the suspicion
So you have some tests in front of you-----preceded by a LOT of rational thinking.
Sure hope Holmes over-thought the problem!
