Hi. New to the forum and boating. I don’t think my question needs the engine serial number to answer as it’s general. I have a 2012 115 on a 19’ Maycraft CC. I purchased the boat recently. At wide open throttle I only get 5200 rpms. The engine seems to run fine but I was wondering if a lower pitch prop is in order. I don’t know what’s on it now. Are props generally marked as to pitch? Thanks.

Glen

Most propellers have their pitch clearly marked on them.

Check your AV plate first for engine height.  When on plane and trimmed, is your plate clearly visible above solid water?  If it's buried you're dragging a sea anchor behind your boat.

Once that is correct, you may gain some rpm's.  If you still need more, then lower your pitch because 5200 on a V4 is low.  You'd be perfect now if it was a G1 I-3 and your height is correct.  [wink]
