Ok, I just bought this engine that came with a rebuilt powerhead and refurbished lower unit. I put 2 hours on it so far following the break-in procedure using a 50:1 ratio in the tank. (It has the precision blend injection system working as advertised.) Is there any reason that a combined 25:1 ratio would cause the engine to perform relatively poorly, i.e. rough idle, sluggish, slow to plane, and surges? Because that's exactly what she's doing. Also, this dealer says that he normally removes the thermostats on these type engines, because they're not needed. It seems to me that the engine would have a hard time getting up to the proper operating temp without thermostats. But I don't know. Maybe there is a compression issue until the rings get properly seated? I guess what I want to know is, how smoothly should I expect this engine to perform for these first few hours?
And since this boat is primarily a ski boat, normally operating with moderately heavy loads, is there anything I should be doing differently right now besides varying the RPMs? At what point should I try pulling a slalom skiier (heavy+fast), or a kneeboard (light+slow)?
