  1. I have original bellows on my 1997 Mercruiser Alpha One Gen 2. There are no leaks or other problems so far, but there are visible cracks. I mostly worry about U-joint bellows, and least about Exhaust one. How often do you replace them? Here are pics: Exhaust 18654A 1 Exhaust 18654A 1 Universal Joint 816431A 1 Exhaust 18654A 1 Shift Cable 74639 Exhaust 18654A 1 Shift Cable 74639 Universal Joint 816431A 1

    Alpha one Gen2 trim limits

    My older 1830 has the Merc 4.3 with the Alpha one Gen2 outdrive. I've recently replaced the trim limit switch and trim sender. The limit switch was adjusted according to directions so that when the trim rams are extended to 21 3/4 inches (if I remember correctly), the limit switch kicks in and stops the outdrive from coming up further using the trim switch. With the outdrive trimmed all the way up to that limit, the trim gauge reads full UP. The trailer switch will then bring it up the rest of the way, only stopping because the ram runs out of throw. I can then hear the hydraulic pump bogging down and know that the outdrive is in full trailer position. when lowering the outdrive using the trim DOWN switch, the rams can be fully retracted to minimum throw and I can hear the hydraulic pump bogging down, the trim gauge reads full DOWN trim, as expected. My question is this: Should the limit switch be stopping the hydraulics once the drive reaches the full DOWN position like it does in the full up position (pre-trailer)? I'm concerned that when on the water and at speed you can't hear the hydraulics. If someone continues to hold the trim down switch, I could see this potentially causing damage to either the hydraulic pump, lines or rams. worst case, I could see a line bursting or the pump burning up and then we have no way to put the outdrive up to trailer. Do I have something incorrectly installed or am I missing another switch somewhere?
