    Any tricks for wire corrosion

    Once that starts, only way to stop it is cut it back to clean copper. Solder won't even stick to it. If replacing it, used the good marine tinned wire. A stop gap I have seen used and actually works. IF the wire is in good shape, aside from the black, is to get some of the grease they use on...

    Mercruiser Alpha One will not trim up, no sound

    Yup, there is supposed to be a screw in there holding it rigidly to the insert.

    Trim position sensor

    Keep us informed... I needed to check the insert position, as I just rebuilt my tansom assy (leaking steel steering pin) and upgraded to S/S steering pin. Doing that means the pivot pins were removed and re-installed, changing the orientation slightly.

    No longer made in USA

    S. Korean stuff seems to be better quality than ChiCom. S. Korea normally has rights to US patented stuff. ChiCom, not so much.

    LED interior lights

    Every Navy and CG ship only runs red lighting any where near the the outside access and in the pilot house to maintain "night vision" when outside.

    the up / down on the mounts should be done equally. There may be some issue with the rear mounts, but if there is on yours, it would be very slight, looking at the witness marks. I think once your top / bottom witness marks are good, the sides will clear up, too. Remember, 2 fingers to push all...

    Correct.... Front of engine goes opposite of heavy witness marks on the grease. IE: Heavy marks on top, front engine mounts go down..

    MerCruiser 5.0 MPI pinging/detonation at higher RPMs

    That dist wobble is surely not right. You can see the sensor gap change as it moves. That will effect the timing big time. Does that dist a 2 part assy / have separate parts that bolt together? I suspect the screws / bolts are loose or MIA. Definitely needs yo come out and be corrected /...

    Engine alignment ,just got the tool. Pics posted

    Good progress.... Heavy marks on the bottom indicate the engine is low in the front and the mounts need to be adjusted UP. Adjust engine to move opposite of marks. Then go from there. Can be a long, sometimes painful and frustrating, process of small adjustments, especially if doing it alone...

    With bar removed, can you look inside, through the gimbal bearing, and see the engine coupler splines? Looks like the bar is missing the coupler splines completely and at that angle, you would never get the bar to insert into them. Sometimes the gimbal bearing itself is out of alignment (it...

    MerCruiser 5.0 MPI pinging/detonation at higher RPMs

    Knock sensor (which protects from this) may be bad. But constant knock is not common. Bad gas? Low fuel flow, causing lean mixture? Vacuum leak? Timing advanced too far? Cap bad? Bad ignition wires? As stated above, the scan aint cheap, but cheaper than a box of new parts that won't fix the...

    Circuit Breakers Question

    Highly doubtful all 8 breakers are bad. do you have +12 VDC to ground on one side of the breaker? If not, start tracing back toward the ignition switch. Does the ignition switch have +12VDC to ground on the "B" terminal? Check for 12VDC at the input of the breaker lineup. These guys have a...

    Mercruiser Alpha One will not trim up, no sound

    If trim works down and the trailer switch works to bring drive up, then the trim up limit switch on the left side of the drive probably needs attention. Puck could be bad, a wire broken off (usually most common problem) or the whole unit is kaput. See this link for another post on this matter...

    Trim position sensor

    Just went through this last week. Disconnect the limit wires inside the transom, behind the engine, and see if your trim up still works. If it does, there is a wiring problem somewhere, effectively bypassing the up limit. If it will not trim up, it is the puck on the drive. The sender guts can...

    Purpose of material under fuel tank in aluminum boat?

    I would suspect that installing an "insulation" layer between a poly tank and and it's mounted substrate would be prudent. The minute vibrations between the tank and the substrate would induce rubbing / wear on the poly and potentially cause a leak in the tank. Don't know why someone would balk...

    Drive Creaking noise Alpha One Gen 2 ?

    I can only guess their thinking was it is a "dry area" and grease would last a while. But we all know that if the steering pin starts rusting and gets a little loose and the seal goes south, then water does get in there. By that time a rebuild is in order. Just did my B3 transom assy rebuild...
