    1989 Alpha 1 Gen 1 shift issues

    I separated the lower leg from the upper, and kept the upper on the boat, to change the water pump. When putting it back together, I had the lower leg gear in forward, and every time I lifted the leg to engage with the upper leg I heard a click, and the lower leg moved into neutral. I tried...

    one drive slower to raise and lower than the other

    I have a two engine 1988 boat with 5.7 L mercruisers and alpha 1 drives. One drive makes the typical noise when raising and lowering, and based on my previous experience, raises and lowers the drive in a typical time frame. My other drive is much quieter, and it takes about twice as long to...

    Was this problem resolved? Please post the solution.

    Dear Moderators, At the bottom of each post is the term "report". I don't really know why this word is there, and what the intent was of the person who put it there. I am thinking there should also be another phrase at the bottom of each post, or on the expert's tag line: Was this problem...

    Winterizing Power Steering Cooler

    I find the 1.5 inch hoses on my Power Steering cooler on my 1988 5.7 L Mercruisers very difficult to remove. When trying to get the rear hose end off I cracked the PS fluid hose barb. This was on the starboard engine that does not use the PS unit so I have not yet replaced it. But when I...

    Grey Font color

    Is anybody else having trouble reading the light grey font of the new style forum? Is there a way to make the font darker and easier to read? I know I am getting old but a dark black font color is much easier for me to read than grey.

    greasing u joint alpha 1 - new grease only came out one cap

    I have a 5.7 L alpha 1 and I recently pulled the drive to service the water pump. I was greasing the U joint and the forward joint greased fine. Howeve, for the rear joint, I noticed that the grease was only coming out of one arm of the rear U-Joint. I could not get the grease to push through...

    1988 5.7 L overheat

    I have a 1988 5.7 L alpha drive that overheated in a 27 ft Tiara with two mercruisers. I live on Lake Erie so it is fresh water, but raw water cooled. I noticed a hot oily smell and glanced at my temp gauge and the port engine was hot, so I turned it off. I could hear the water boiling in the...

    Exhaust shutters (flappers)

    I have a 5.7 L mercruiser and alpha one drive, 1988, and serial number B784582, that recently overheated. I pulled my outdrive and found four shutter plates in the bell housing. Upon separating the upper from the lower, I found a melted water pump housing and a melted copper pipe housing. Thanks...

    Laying on top of twin 5.7 L engines

    I have a 1988 Tiara 2700 with twin 5.7 L alpha 1 gen 1 Mercruisers. Working on these engines, winterizing, cleaning up connections, getting to the starter motors, trim pumps, changing oil filters, etc, is hard to do from the front, sides and middle. I find that it is easiest to place a...

    Zincs (or Magnesiums)

    I have two boats right beside each other at a Lake Erie marina, a sailboat and a Tiara 2700 with twin I/Os. The sailboat has a zinc on the prop shaft. When I pulled it out for Winter the zinc was in good shape, very little evidence of electrolysis. This zinc is about 10 years old. I very...

    I have a twin 5.7 L 27 foot Tiara serial numbers: Port: B784582 Starboard: B784568..I noticed hard steering the other day but it was manageable. After docking for a few hours, the steering returned to normal. I attributed this behavior to stiff grease in the ram tube because of the cooler...

    Ball Valves on engine to make raw water draining easier

    I was wondering if anyone had good luck or advice on installing ball valves in place of the 1/8 inch plugs on 1980 vintage Mercruisers. Then instead of standing on your head trying to unscrew the plugs, you could just turn the ball valve. You could also probe the opening with a piece of wire...

    Ned more steering friction - twin 5.7 L alpha one - first generation

    I have a new to me 2700 1988 Tiara Continental with twin 5.7 L stern drives - alpha 1 gen 1. I have been having a hard time learning how to maneuver using only my shifters. Today I realized that the steering wheel wanders when I was practicing. As other have noted, if the helm is not dead...
