Thanks for the information on the smoke. Never really noticed it before then again wasn’t really looking before so I wasn’t certain. As for in the second video at the 17 second mark is when the rpm jumped to almost the rev limit and then around the 24 second mark is when the rpms drop back to around 5000 and then the boat felt like it was getting power. But between that time slot the boat sounds like it’s revving in neutral when in a car. But I will try not Gunning the throttle and do more incremental moves to see. Concern is that something else that could be engine related. But appreciate all the advice and recommendations. Will definitely look at sealing the intake tunnel and see if any difference.

i think you have a bit of cavitation, but nothing so far indicates that there is something wrong With the engines
