They have consistently given me great service and advice over the last few year.
Just had to replace an SP55s motor on our stern thruster. Imtra gave me a good deal on a reconditioned, upgraded SE60 unit with a generous previous customer discount.
And, yes, the motor can be removed with the boat in the water. The gearleg, no.
Their website gives prices (you have to hunt a bit) for the various motors. Those are for new units. Call to see if they have any recons.
