My, how time flies. My schedule and weather just haven't permitted moving forward at a faster pace.
It took some doing, but the tech that I asked to raise the motor kept refusing, as he is afraid I'll bring the boat back to him with an over-heated engine. He couldn't have been more clear with his protestations, and I imagine I'll get an earful when I see him tomorrow. He was reluctant to believe what I have read here, from devoted SC owners.
So, he finally raised the engine (needed to drill 4 new holes, and fill the old ones) so that the anti-cav plate should now be 1 1/2" above the level of the keel (I'll see it for the first time tomorrow, weather permitting).
I'm running a 2008 OptiMax 2-stroke, prop is 15 1/2" , 17P, Mirage Plus, getting 5200rpm at WOT, moderate load. What should I look/listen for during this shake-down cruise? I know the 2008 150hp OptiMax has overheat protection (buzzer, automatic throttle reduction), but I'm just wondering if there's anything else negative to look out for? Might it cavitate more on hard turns, and is occasional cavitation normal when plowing through wake while turning? I'm fully expecting quicker hole-shot, and more level WOT planing, with less lateral spray from the motor. Should I also expect higher top-end speed (currently around 41mph) and higher revs from the engine, as well?
Thanks agains for the help. I hope I've not come off as an insufferable newbie with all my questions.
