Hi!
I have been running my SS 2000 comp (center steer) with merc 280, sportmaster 1.87 fat shaft and lightning et 14,5"x30" prop for three years now.
I have been running 106-108 mph (on the limiter) with perfect balance.
This spring I hade to raise my motor to make it fit in a garage. Afterwards I lowered the motor down to the same height as I thought it was before. When running after this maneuver I don´t think the balance is as good as before.
It leans to the left when I reach 100+ mph and when I trim up to make it fly straight it feels like the nose goes higher an higher until I don't dare to carry on. It even feels like I have to make a long long right turn at 100 + to balance the boat. Earlier the boat leaned to the left when running with too little trim, but when I trimmed up a bit it was all perfect. And when I trimmed too much it started to lean to the right (which never happens anymore)...
Obviously the engine height isn't exactly the same as before (should have been more careful when changing the engine height). Question is: Do you think my motor is lower or higher than before considering the characteristics described above?
As for now when measuring the engine height, I would say the prop shaft is 3/8" above the pad (don't know exactly how it was before but I know for sure it was above the pad). My bet is that it was even higher before but I don't dare to raise it even higher with stock pad and stock sport master risking blowout at 108 mph.
At speeds lower than 90 mph I can't really tell any difference from before.
What do you guys think
Thanks in advance!
