hi everybody, long time lurker, first time poster. i have an m6s-111 that as the oil heats up, it takes longer to engage going forward. if i run it for an hour or so and have to stop for something, it wont go forward at all. reverse works fine all the time. from my research im leaning towards a relief valve? is that something i could fix? im 3 hours from anybody big enough to work on an m6. any help is greatly appreciated.
