Mercury 75 ELPT EFI 2018

Motor cavitates at about 3600 RPM or above on 20 ft Harris pontoon Runs better with full tank of gas & passengers in back. Has 20 inch shaft. 4 blade prop. Need to check pitch. Prop had no sign of burn. Guessing pitch of prop could be steeper to resolve or need to lower motor mounting. If not prop, 25 inch shaft may solve. Not very cost effective. Panther vertical trim may work. Panther unit is $650. Welcome input
