I have a 2006 Regal 1900 with a 2005 Volvo 4.3 GXi and SX outdrive. I have noticed lately that after I get the boat up on plane and trimmed out, the drive will start trimming itself back down. I can tell this by the trim gauge and the my GPS speed. This will ahppen over about a 10 minute...
Has anyone tried a different prop on a 1900 with a 4.3l? I am currently running a 3 blade aluminum 14.3 x 21. I would like to get on plane a little faster when pulling a skier. Currently, RPM's @ WOT are 4600.
