I searched for all the 21X3 threads and found some useful info but thought I'd ask a couple of questions of my own. I posted about a suspected engine issue in the 3.0 Merc forum but wanted to see if this could be more of a setup/hull issue.
I'm currently running a 25P Tempest Plus. Can spin it to upper 5900s RPMs and today it ran 66 MPH with my partner, most of a tank of fuel, tourney load and extra water from rain. However, I have to get to full speed trimmed all the way down before I start to trim up or I seem to be limited to about 5k RPMs. Today was kinda rough with wind and lots of tourney traffic, several times I'd be running along and hear the engine change. When it changed, the RPMs drop. Most of the time I could hold it WOT and it would come back when I hit a wave a little later. I can also come to a stop, trim all the way down and start over and run full RPMs again. Has anyone experienced this? I'm going to reach out to my mechanic when he gets back from vacation to have him see if he can find something but it seems strange how it happens.
Second, I have a 27P Tempest Plus and a 26P Fury 3. I've tried the 27P when the engine was acting up so I don't really have good data on it. Any one have success with a 27 Tempest Plus or 26 Fury? Thinking I might take the 27 and get it repitched or sell it and the Fury to buy something else.
