I have a 1973 Pearson 30
with a yanmar
I took a long trip a few months ago. Had to motor
sail half the way back.
Well, the alarm
wasn't plugged in so I didn't hear the motor
Not exactly sure how long the motor was overheating
, but it did damage. I'm surprised it didn't blow up.
The sea strainer melted and the water muffler
Those were the noticeable damages. Replaced both.
At this point, the motor runs but on startup a good amount of black smoke and black door (unburnt fuel) come out. If I run it at 2500-3000 Rpm
for about 5-10 mins, the black clears. Until I put it in gear
. Then while in gear
, it will smoke and soot the entire time.
I checked the fuel
lines, and changed the 3 injectors.
This has only happened after the overheating incident.
Friday, I have someone coming out to clean the bottom and check prop buildup, but that won't have anything to do with smoking and soot and startup.
What are my possibilities? I started up (for seconds) without water muffler
attached and black smoke was thick. Another ailment is the motor is slow to decelerate and to shut down.
