  • why its important to pull the drive yearly and do proper maintenance

    so, this boat came to me after the owner heard it makign noise and shut it down, then it would not start again,
    the studs holding the flywheel and coupler to the crank had al lsnapped off and the flywheel was sitting on the floor of the bellhousing.
    in pulling the engine, i had to remove the drive assy, when i di this the drive was s severly stuck in the would nto gimbal when i used the trim cylnders ot crakc it loose, the whole bearing carrier tore away from the drive and was lodged into the pivot housing.
    the owner told me how good the boat has been to him for the past 5 years and all he really di to it was change the oil, oh and he put sa new starter in, which also had a broken bolt n the block that he di not feel necessary to repair. . i spent a day soaking the pivot housing in rust buster, but that did nothing, along with using an air chisel(hammer) but the carrier would not budge, finally i went in with as sawzall and cut the casrrier in 2, which gave it some space alowing me to chisel the 2 pieces out to reveal the ****e corrosion inside the housing. there is over $1800.00 in parts needed to repair this and over 2 days labor, including sending the engine to the machine shop to remove 6 crank bolts and 1 starter bolt from the block`
    so, the lesson here is: pul the drive yearly, lubricate the spines, check the alignment and inspect the bellows.
    Maintenance is your vital

        It amazes how many people I talk to that seldom pull their drive. Fortunate for them most boat in fresh water which helps a little. The obvious reason is to inspect gimble bearing, U-joints and bellows but also to re-grease the mating surfaces that allow separation of parts in the future.

            I just pulled the drive after 5 years (SX-M) mainly due to a noisy gimbal bearing this spring. I could not believe how easy it was....I felt intimidated by the procedure and put it off....but...why?

            That the double-u-joint driveshaft asm is a ~$330+ assembly without individual repair parts should be enough motivation to get in there and lube it if it has zerks but if not, at bare minimum,. make sure the upper bellows doesn't have any water in it...
