Purchased lightly used 2006 305 Conquest - original Verado 250's with 200 hours each. Runs and performs well but I don't get near 5400 minimum spec RPM at WOT. Best I have seen is around 4600 - 41 MPH. Props are 19 pitch. Mechanic checked engines at purchase for problems, fault codes etc but he was not available for the sea trial. I noticed the low rpm at that time but the boat was immaculate and I took a chance on the sale.

Trimming engines out way out??

Are all the plugs in? Valves closed?

Fresh premium fuel?

Props are 19" pitch WHAT? brand, model and size (diameter x pitch)?


I would be worried there is an issue with such low hours. I would have a factory trained Verado mech run the boat. These are fussy engines.
