Hello....<br /><br />I have a 2 altenator / 3 battery system. When I am at 3000 or more rpm the voltage gauges on both engines drop. When I return back to idle they go back up to around 14 volts. I have checked the belts. Was wondering how to tell if the isolator is going out?<br /><br...
Hello.<br /><br />Having difficult time troubleshooting a noise. I heard it when I came in from the lake and had the boat in neutral at the dock. I rev'd the motor to clear it out and around 1800 rpm i heard a growl. I idled back up to 1800 rpm slowly and noted the noise drive trimmed down and...
recently overhauled an A1/G2 drive gearcase.All new bearings & seals. I noticed today that when I put my drive into gear or in neutral it makes a slight whine/howl type noise. It will increase in tone as the rpm increases and then seems to disappear after 11oo rpm or so. Or at least I can't hear...

Hello.<br /><br />I have alpha 1 Gen 2 drives. I changed the u-joints and when checking the alignment noticed that the grease lines "tracks" were not even all the way around the alignment tool on the starboard side. I adjusted the engine up in the front and made sure both sides had equal threads...
This boat is a 1999 Chaparral 290 Signature Cruiser twin 5.0L and alpha 1 Gen 2 drives. The lower units of the drives have been overhauled last season and by just hand twisting the u-joints without seeing any slop we decided they were ok. I am noticing a vibration more from the starboard side...
Does anyone know what the correct way to install the water pump dam in the upper housing is? Both Merc Man #14 and Clymer shows it opposite of the way it was when I opened the drive up. Can anyone help?<br /><br />Thanks<br />Pete
Hello.<br /><br />I have heard that the A1/G2 prop shaft is made from 2 different metals that are friction welded together to make up the shaft. Does anyone know if this is correct?<br /><br />Also, what is the prefered way to correct a slightly out of spec shaft using heat or just using a...

I have a 1999 boat with a 5.0L and alpha one drives (2) The starboard trim indicator is at times erratic - the needle on the gauges jumps. I have checked the connections at the gauge. Have traced the wires in side the boat all the way back and have found no problems visually.<br /><br />How do...
I have a twin engine boat. 5.0L carbs. It has Alpha 1 drives counter rotating I believe. I am experiencing a slight vibration from the starboard outdrive. When running together a slight vibration is noticed in the floor. Even though for the most part the operation seems smooth. All seems fine...
