Hi John, good morning, my name is Jason.

What is the history on this engine? When was the last time it made full power? Have you ever seen it make full power?

How old is the fuel itself?

Have you done any testing on your own yet, namely spark and compression testing?

Customer: replied 9 months ago.
Hi Jason the fuel is brand new I have ran boat 25 to 30 times since Jan fishing I had kinda same trouble a month or so ago where it was kickin the slow mode in that's why I changed line and bulb then the power pack it was running great and last week started to slowly loose peer till it finally is always bogging after around 3000 rpm I also had to takin off about 3 years ago

Expert:  Jason replied 9 months ago.

Have you checked engine compression and spark output?

What happens is compression and spark output need to be checked first. Compression is a pass or fail test. If it's missing spark then the ignition system needs more troubleshooting in order to figure out why. If compression and spark are both good, then the problem is going to be in the fuel system and there are steps to troubleshoot that. But we need to know first if the engine has compression and proper spark. Are you able to do those tests? Do you have a compression gauge and either a spark tester or a timing light?

Hi John, I tried to accept your request for phone service but the system says your payment failed to authorize a phone call. If you want to get that straightened out you can contact customer service at *****@******.***

At idle I'm down to like 10.5 volts charging and when bogg is at around 3000 rpm it goes to 11.9 to 12.1 volts if I can get it to rev it usually would go to 12 . 7 is highest I've seen and that reading is from my hummingbird 898
Expert:  Jason replied 9 months ago.

The charging may or may not be related, there are other things to check before that.

How are you testing for spark specifially?

Expert:  Jason replied 9 months ago.

Have you tried pumping the primer bulb over and over to force fuel to the engine to see if it picks up?

Do you have a decent quality volt/ohm meter, and can you take resistance measurements?

Customer: replied 9 months ago.
I've updated for call grounding from a solider copper wire that I attached to bolt on engine block and yes I've pumped primer and made no difference
