I've been adding Seafoam to gas, will try some of the Gum Out.So I swapped out all the upper fuel lines to both engines (the ones that are easily accessible from above) as well as the lines to the carb on the port engine (the one that gives me trouble). I purchased new line at the local auto parts store. Automobiles all use the same ethanol gas so I figure they should be OK (anything should be better than the original lines from 1999).
To get to the carb lines you have to remove the air silencer (the thing that looks like a blanck boat bumper on the side of the engine) and the flame suppressor. I found my suppressor, which is just many layers of metal screen, to be very clogged and dirty so I cleaned it with carb cleaner spray. Did the same to the carb opening (also kinda dirty looking). Swapped out those final lines, sprayed in lots of bar spray and put it all back together. Still need to do the starboard engine later.
Tossed a few cans of Gumout into the next load of gas and ran it hard. A little smoky exhaust for a while (OK, it seems like I was generating cover for a beach landing by the marines) but it cleared up. I've not had the power surging problem since then. More so than the new lines, I think the carb cleaner was the real helper here.

Dealer near me only deals with jet skis. A friend that used to work on boats did the work and said I don't owe him anything, but I still want to pay him, I just want to make sure I pay him enough.I know he could use it, and I would like for him to help me in the future with my boat.I would suggest giving your local dealer a call to see if they can provide an estimate, do you have one close by? Keep us posted.

Decided to try to crank it one more time before taking fuel line filters off to check them and it started up. I drove it around some in my cove and it seemed to be fine. Thanks for the advice, if it does it again I will check filters.

Can I leave boat in water to check filters? I don't mean to sound lazy but last time I put boat in water in July, I slipped and bruised my leg and still have knots on my shin so I just leave it in the water at my dock.

Use a clamp if you want, but it may not even be necessary to do that. Just make sure you put something under to catch any that might spill and do not reuse.
