" when first using my boat,the 41a bogs.Even after being warmed up.When held wide open, only turns to maybe 2000rpms , after 10-15 sec.it will kick in and turn to 3200? After that it seems to go fine and take off fine . I've tried the following ,injectors,turbo,fuel filters,tank pickup, there was some sludge intially but I have taken care of that. Fuel pump ? Also had the prop recon.from 20x20 to a 19x21 . Alot of smoke at first takeoff. "

" when its under a load.Grey/black smoke.With no load and warmed up it turns to 4200rpms,after being used.Thanks for the help.I haven't tried to clean it out when tied up.No load. "
 
" gray/ black smoke is a sign

" gray/ black smoke is a sign over fueling or lack of air.you say you check the turbo,dose it turn very freely when you flip the impeller or is it a little stickey? chould something be causeing high exhaust back pressure?how about the air strainer?
when tied up to dock it whould be nice to know if
it acts the same as under load "
 
" the engine clears out when r

" the engine clears out when revved ,tied at float.Another thing,it has wet exhaust,possibly to small diameter-its 3.5 id. The turbo spins freely with no hanging up.Air cleaner is clean and new. It acts the same when tied up.Also its starting hard,fires rough at first then starts picking up.? Cold climate 20-30 degrees. "
 
" it now sounds like the fuel

" it now sounds like the fuel system is looseing pressure.are there eny fuel leakes, dose the system have a check valve. mit try primeing the system next time befor stsrting engine.the wet exhaust mit becaused from rough runing caused from the fuel system,the cold climate don,t help "
