2005 26 commador Bravo 3 drive 350 mag mpi
When trying to get on plane boat stuggling at 3000 rpms running fine at 2000 rpm
Usually at start full throttle goes 3500 or more out of the hole then as it gets on plane rpms up and I can back off to keep on plane around 3500 rpms
1 water fuel filter no debri put new filter on
2 inline fuel filter to check ?
3 fuel pick up?
4 fuel anti siphone check vaule?
5 Bad gas?
6 will check fuel rail pressure I think should be 40 psi?
This boat burns 11 gallons and hour I guess that is a fair amout flowing ?
Looking for easy way to solve my problem
ThanksJoe

Well found my problem and it was not fuel related 1 bad plug lose and no electrode left also replaced distributor cap and rotor back up on plane in about 10 sec. But new problem picking un a vibration a low speed 1 to 2k rpms. I had just pulled outdrive to replace the clone clutch, gimble bearing and ujoints looked good.
Seems to be worse when warmed up worried my have created a problem in clone clutch replacement
Any Ideas how to track it down props clean no dings.

Thanks for reply/what you found! Not good one electrode gone on one plug, get compression pressure tested on that cylinder checked. Should be around 150/170 PSI. Electrode (center or ground went somewhere) ! Hopefully not stuck in exhaust valve/seat!

Sounds like a general tuneup might be due. Replacing all spark plugs and wires can do wonders with hesitation, misses, and lack of power. Also, no anti seize on the new plugs.
