thanks for the input guys!!

Talked with the servicing dealer yesterday and they looked up the work order. Looks like the fuel filter they put on was not a merc...it is some aftermarket thing, i cant recal the name right now. They hope it doesnt flow the fuel that i need and its the source of my rpm loss. They gave me a merc filter which i will install later today. If the weather holds we should be out on the lake tomorrow. I will keep my fingers crossed and post the findings out.
Thanks for all the help here, it is very much apreciated.

Hey guys.. A little info....

Changed out the fuel filter but didnt check the plugs on Sunday and went out for a ride.....

The rpm's were still down......I will check the spark plugs.

Another interesting note- the dealer said they installed an extra litre of oil then what the manual called for......could this also be part of the problem??

Nah a liter will not hurt!

Take the plugs out and do a compression check. You may have a damaged engine.

Just an update as to my findings....
-2 liters of oil too much from dealer oil change along with incorrect fuel filter.....
-engine overreved and put into guardian mode
-crankshaft position sensor code activated-upon start up 350 rpm
-camshaft position sensor code activated- ypon start up also

-Cleared all codes, drained oil to proper level and seems to run a constant 4900 rpm, cannot trim anymore or the boat will loose mph.

Thankx to all that have help with their input, it was greatly appreciated!!
