2006 rinker 262 prop question

robertcr

Just purchased a 2006 Rinker SE 262.  It has a 5.7 GXI - 320 hp - XDP drive.  Wide open throttle is 45 mph, and 5800 rpm.  I know it should run between 4500 and 4800.  I have  a F4 front prop 3851464 5H, and a F4 rear prop 3851474 5H.  What prop should I be looking to get for an rpm of 4500-48000 wot.

2006 pentas had a rev limiter at around 5400... Mercs around 5200... The newest models can nail north of 6k due to supreme balance and robust fuel monitoring equipment, but that's another story.. your story is about a lying tachometer... Get a quality shop tachometer on it, or a computer polling live direct from the pcm and see what the true rpm's are.... The rev limiter can be programmed out, but I doubt anyone would do such a silly thing unless they built a motor to support it, which means either you've got a bad arsenal engine in that rig or your tachometer is lying... I'd wager on the tach.

Thanks 212rowboat.  I will check the tachometer before doing anything else.  That was my first thought as well.
