Hello, my name is***** will assist you.
Can you remove the spark plugs and check the tips of them to see what color they are?
Well, that would be a reason to be down on power. Lets find out why. do you have a multimeter?
If you can get a spark tester, that would be great. Yes the multimeter had the red and black leads with it.
What is the full model number of the engine?
Left hand side of the engine. On the swivel bracket.
Yes that is it.
can you get the meter and test the one clean plug?
No worries, thee no time limits here. Just reply back to me when you re ready
Ok, first remove that spark plug. Set the meter to read resistance. Touch one of the meter leads to the end where the spark plug wire goes on the plug. Touch the other meter lead to the threads on the spark plug. There should not be a reading there. then move the lead that was on the threads to the center electrode. What is the reading that you get there?
The fuel pump is located on the side of the engine block. If there is one on the boat fuel water sep filter, I have never seen that. Would not be a factory item. Can you post a pic of that?
