I have a 2007 Glastron GT190 with a Penta Volvo 4.3 i/o. The trim motor failed with only like 130 hrs!!! I thought it would be a no brainer to fix but no dice. The trim motor is on the back of the transom under a plastic coverThe say you have to remove the drive unit to get it out but you really dont. Just crank the streeing wheel starboard and you can get at it using a variety of 1/4 sockets 10mm to be exact. The shock and ave came when I found out that these cheap motors retail for from $850 to $1900!!! You actually have to buy the motor, pump, cover and hydraulic lines as a unit? Go figure.
I took the motor to an excentric old guy who first said it couldn't be rebuilt becasue of a "circuit board" mounted on the brush assembly. It's not really a circuit board per se it's actaully a resistor and capacitor utilized to slow down the motor but have no effect on the functionality of the motor. These components are actually the achiles heel of the motor resulting in premature failure. He simply by passed the components and ran the wires directly to the brushes and it works great!!! It's actaully an upgrade over the failure proned OEM Unit.
One word of caution when reassembling the motor make sure you attach the two allen screws on the front of the unit that serves as a clamp holding the hydraulic lines molded into the cover to the hydraulic pump. It can be a little diffcult getting everything aligned in the tight work space. The outlets of the pump actaully press directly on to the plastic cover and sealed only by two tiny 3/16ths O rings.
I hope this helps someone save $$$$$
