    Mercruiser Alpha 1 Trim Adjustment-gctid803698

    The trim on our new Bayliner VR5 hasn't been adjusted correctly, the needle on the gauge goes past the bottom indicator point before the outdrive has reached the full in position. I can't be bothered to take the boat all the way back to the dealer, so I'll have to adjust it myself.

    I'm guessing it's not too complex a job to adjust the setting, but having never had to do it before, I would appreciate some guidance please.

    The first issue I came across was how to get to both screws on the trim switch, I can get to one, but the second is obstructed by the outdrive housing/body?

    Any help would be greatly appreciated.

    Thanks....

    Turn the wheel to expose the other screw. Adjust the sender one notch at a time and check the gauge. If it's worse adjust it the other direction. These trim gauges are often out of whack and need adjustment. Lots of the fellas trim be feel/sound etc.

      It suddenly dawned on me at around 05:30 that I need to turn the wheel to expose both screws, definitely a Homer Simpson moment!

      Thanks for your advice, I'll have a go today.

      It's a shame the supplying dealer didn't check this before delivery, but what the hell, it's only a brand new boat!

        This was how the gauge was set up on our 175, and its the same on our VR6, on both boats when lowering the trim, the needle drops below the bottom line before the change of sound that indicates it has driven to its max down/in position, our dealer seems to think that's how they are intended to be, so I just accepted it, now you've got me doubting that comment.

          Our VR5 has the same issue...

            It was a fairly simple task to adjust the trim setting. The gauge now reads accurately i.e. the needle is on the bottom mark when the leg is fully in.

            Thanks for your comments and advice.

            Cheers...
