Have Boat Questions? Ask a Boat Repair Expert.
Hello, my name is***** will assist you. I have a few questions back for you.
What is the brand, and HP of the engine?
What is the brand and model of the boat?
What pitch prop are you using and what is the max rpm that you can get out of the engine?
How long has the engine had this issue?
Alright.. Do you know the compression numbers on the engine?
Alright, we are going to need to start there and do a spark test. If it is way off, the engine will never run correctly, no matter what I have you do. You should be able to rext a spark tester and a compression gauge from a chain auto parts store.
It could yes. Idle and speeding up would be affected.
The engine will run on as little as 80 PSI of compression on all 6, but it will not have very much power.
Simply reply back to the thread as you have been doing already. I will get the reply and we can pick right back up where we left off. Make sure that you pull all 6 plugs before starting the test.
