Hello all, I am, the new owner of a 280 DA, we downsized from a 300. My new 280 is a 2005, has twin 4.3l engines with Alpha 1 gen 2 counter rotating drives. The previous owner had for a year, and had a survey done. On that survey, it was noted that the rev limiter was reached at 5000 RPMs when fully throttle. My mechanic noted it during my sea trial, and of course, I am experiencing it now using the boat. All have said I need to change the props, perhaps to a 19P. I currently have the Vengeance 17P props that are original to the boat. I also verified that these are the original props see ray put on via the part number. So my question is does nthis make sense to any other owners? Why would the original props hit the rev limiter? The enginmes run grate otherwise. 240 hours on each. I am used to BIII drives so this is all new to me. Also, I have noticed once I am up on plane, and try to trim out the motors, if I go more than 1 or 2 trims up, the RPMs start to rev high. Again, just looking for some insight before I invest in new props for the boat. I obviously want to get this right. I also notice that when I cruise at apporox 27 MPH, and I hovering around 4100 RPMs. I have been burning a lot of fuel, and that RPM seems high to me for that cruising speed. Again, p[lease forgive my ignorance, i am used to 350 MAGS with BIII motors. thanks again
