I have a '99 380 Dancer that's been amazing, however, I'm not getting maximum RPMs at WOT. I always check for WOT performance at the beginning of the season with a clean bottom to get a baseline, and to see if anything isn't working right.
I traditionally get to 4,500 RPM at WOT (should be 28kts according to SeaRay), but cruise at 3,400 RPM (approx 18kts) with 1/2 fuel, 1/2 water, supplies, and 4 people. This year I'm only getting about 4,200 - 4,300 RPMs at WOT (approx. 22-23kts). The engines seems to be performing well - FWC is cooling, new oil & filters, clean air filters, etc.
I suspect it might be my props since I didn't get them professionally cleaned or trued (I skip that once in a while when the wheels look good, and there's no visible sign of wear or damage), however, I cleaned them up reasonably well with a wire brush and emory cloth.
Before I begin to suspect a possible engine issue, and start compression testing, i want to see if anyone else has a similar issue, and confirm my suspicions that it's probably the wheels. Thanks!
