    Done it all and still some noise

    New gimbal. Ujoints, stub shaft, lower carrier, new prop and hub, and I still get noise when outdrive is all the way down, and all the way up. Noise is better mid trim, but is audible when turning. Any suggestions?

    Tried a 19 not impressed.

    '93 4.3 Alpha one, 17 ft boat. Usually ran a 21 at 4800 wot . Wanted something that pulled a tube easier. Tried a 19 pitch and it wont plane unless I stomp on it. The bow shoots up higher and it takes a long time to plane unless people are up front. The previous 21 took off like a shot. I'm just...

    Noise when pulling a tube.

    '93 4.3 Alpha gen2 drive. Went thru the wringer last year at the shop and did gimbal, ujoints, stub shaft ,prop shaft carrier etc. My boat still has what sounds like a bad bearing but it's only really noticable when added load is put on it. ie- tubing. Pulling and turning with a tube is the...

    1993 mercruiser 4.3 alpha one noise

    Got the boat running shifting great now. There is a noise when turning like a bad gimbal bearing but mine checked ok. I notice it way more pulling a tube. Could it be input shaft bearings? My u-joints were good too. It vibrates thru the hull. Thanks.

    4.3 Alpha one shifting problems

    1993 4.3 alpha one gen2. Just had major service done-bellows, lower shift cable, impeller, propshaft carrier. Been having shifting problems . The interrupt seems to be working, but I' ve gone back twice now and it's never right. Reverse is fine, neutral to drive sometimes ok. Sometimes a...

    Hook in hull

    I looked at my '93 Glastron and there is a bevel or dip just before the transom. It is pretty uniform all the way across. Is this factory or a hook? Anyone got pics of what I should be looking for? I'll take a pic of mine.

    Trim levels

    Is it normal for some boats (mine) to run full trim and not porpoise or cavatate? Seems I always needs full trim to maximize speed, while my buddies trim levels seem much lower. 1994 Glastron ssv 175 4.3 alpha w/4 blade 20 pitch alum. Maybe I shouldnt be comparing?

    Shift interrupt

    1993 mercruiser 4.3 alpha 1, got the boat out of service and its a real dog to get out of gear forward and reverse. The shifter feels stiff and it keeps on in gear when in neutral. Just had the lower shift cable replaced. Is it something I should adjust, or back to the shop? Is it typical for...

    1993 Merc alpha one vibration

    History- last fall I hit an underwater rock shelf and took out my prop. Since then I've noticed some vibrations at idle speeds, which would even out at cruising speeds. This spring I noticed some water in my lower units' oil, but not a lot. First run if the year, had it wound out pretty good...

    1993 Glastron SSV 175 prop for raising bow.

    4.3. Runs great with 21p prop. 45 mph @ 4800 . There seems to a lot of hull in the water at full trim. The prop I have has no cup or rake really. I was thinking of the alpha4 20 p . Any suggestions? If I run trim down it really plows.I've been told it looks low in the bow as well. Thanks.

    1993 Glastron 175 SSV Elite prop choice for bow lift.

    4.3 engine with a. 3 blade 21 pitch. Boat seems to run flat even if trimmed up all the way. My prop is old no cupping and hardly any rake. I get 45 mph at 4800 rpm. Holeshot is good. Eveyone thinks it runs flat. Was looking at a alpha as blade 20 pitch. Would I get more bow lifft? Or...
