I be noticing more cruising full throttle and sounds like it drop down a gear like a automatic trans mission from "D" to 2nd gear . RPMs wines up , runs a little bit and like shift back to drive , RPMS goes back down tales off again . My RPM gauge not hook up but my speed goes from 15 mph to about 10 or 12 mph . I used to only notice it in a turn but not be going along in a straight stretch and does it . Most of the time it only last about 15 or less . It on a 20ft Pontoon boat . We have had this boat 3 years now ,take it out 3 or 4 times a year and run about 2 to 4 hours each time .
