I recently purchased a 1984 Bayliner Capri with a Force 125.
The boat has been in storage for 11 years and only has 140 hours on it.
I removed the carb bowls and removed the sludge and old 2 stroke oil and cleaned the carbs out with a can of carb cleaner. They are very simple carbs so it was pretty easy to do.
The tank was half full and as I had no opportunity to drain it, I filled it with premium gas at 50:1 with a good quality 2 stroke oil.
A new battery and after a few coughs and splutters it jumped into life on the hosepipe.
I checked the oil in the lower unit which was very clean and greased everything that needed greasing and launched the boat.
I launched her this morning - thankfully no-one around to complain about my smokescreen
The engine is very smooth and quiet - only issue seems to be that it wants to stall if you just slide it into gear - more so in reverse than forward - if you are quick to get on the gas it's fine.
I ran up and down the lake at 2000 rpm and she was as smooth as silk. I could launch quickly from zero to full throttle with no hesitation and there is lots of water coming out of the exhaust that was hot, but not boiling so the impeller seems ok.
So far so good, however....
The engine really smokes - I'm assuming that this is because of the bad gas mix and should improve as I get rid of it and replace it with fresh.
Am I right that this motor is 50:1?
At full throttle, trim full down, the boat was at 37mph @ 4000rpm which seemed a bit low, if I raise the trim I increased it to 40mph @ 4200rpm
I'm assuming that I have the original prop which would indicate that the engine is down a bit on power - not surprising after 27 years.
After about a minute or so at full throttle, the engine starts to sound less comfortable and starts to hesitate and lose power - if I back off and reapply full power it runs great again for about a minute. To me this sounds like a lean mixture - what do you think? The primer bulb is not compressed so it's not fuel starvation.
What do you think, leave it alone until I have run it for a couple of hours and got rid of the old gas, give the mixture screws half a turn anticlockwise to richen it up a bit or what?
Still learning about this outboard so please be kind
