Picked up some "new to me" power for the seacraft
 

So i just picked up a 2002 yamaha 250 ox66 for the SeaCraft. The motor is a left hand from a split pair and has 350 hrs but got a new power head that only has 100 hrs on it. Picked up the motor for $4000. For an additional $500 the guy gave me all the rigging (i.e. main harness, throttle, throttle cable, newer style tach, fuel gauge, Oil tank, Oil tank harness, etc.) and a prop. Some of the Rigging is brand new still in the sealed bag from yamaha. Since he only had one left hand prop i ended up with a 17p mirage plus SS. Not sure of the diameter as the motor and all already went to the shop where the boat is being worked on. So is $4500 for all that a good deal? And is there a different prop i should get or is that one a good prop for my application? Hopefully the boat will be done here in a couple of weeks. Cant wait to get back out on the water.....

Sounds like a pretty good deal to me. A "lefty" would probably be fine on a CC, but not too good on a Scepter due to the Starboard side helm placement and rotational lift of the prop. Prop on a "lefty" spins counterclockwise which causes the motor force to rotate the boat clockwise a.k.a. to the right hence lowering the starboard side of the boat slightly. Add the weight of the driver on that side and it causes the boat to list to the right/starboard side will underway on a plane. Ask me how I know, LOL!

But get a Sceptre with a "hook" on the bottom and it will counter that affect. My dad's '82 would list to port without using tabs running a right-hand engine.

That is the norm, especially if you steer while standing more in the center of the boat than directly behind the wheel on a Sceptre.

As you mentioned, trim tabs will correct all of these slight variations.

That is correct. I lave a bracketed left rotation F250 on my Scepter and I have to use the trim tabs to correct the "pull" toward the helm side. This is very pronounced when I am alone in the boat.
