SN 1B289627, 2006 275XL. My brother recently purchased a triton 240LTS with said motor that has 68 hrs on motor. Having a problem with motor not shifting into reverse. Will shift into forward and neutral with no problem. Can shift into neutral but Smartcraft shows a Fault Shift Act. Took motor to a tech and he checked the actuator which he said was fine. He said he had seen the problem before. He replaced the isolator seal which he said was cracked or needed to be replaced and that it was getting too much air and causing motor to rev too high which would cause the computer to throw a code. Boat fixed, took back to coast and boat worked fine all day. No problems with shifting in and out of reverse. But as he was power loading onto trailer the code was thrown and reverse has gone out again. Any ideas as to where to start or has anyone experienced this problem and had it resolved. Thanks for any input.
