    Alpha 1 Gen 2 - leak & transom service questions

    The seal on the front timing cover you can replace by just removing the harmonic balancer and then pop out the old seal and install a new one. Just go to your local auto parts store and ask for one for a 1999 S-10 with the 4.3, you can pick any vehicle with a 4.3 to have them look it up. I’d try...

    My block is drained, right?

    I’ve found that O’riellys near me actually stocks the Sierra PG antifreeze. I try to capture what I use each year to use again the next year and test with refractometer. Price isn’t terrible, $29 and it make two gallons...

    4.3 diesling

    My old boat with a 4.3 would diesel if I ran it mildly and shut it down shortly after coming to idle speed. My fix - run premium gas or if it was easy to get at a fill-up ethanol free.

    On my Alpha 1 Gen 2 the shift cable had a plastic spiral warp on the cable for protection that needed to be removed first. Just reach in and unwind the wrap, must be done from inside the bilge are.

    Replace Transducer Mount - Seal Old Holes

    On a new-to-me boat the transducer mount was broke. I ordered a new one and need to replace it. The previous owner used what appears to be silicone on the original mount. I have 4200 and was going to use that. What can I do to clean out the screw holes to ensure that the 4200 adheres well and...

    Help! Coupler Wobble and Alignment Issue? 2005 4.3L MerCruiser Alpha 1..

    Is it possible the coupler sat for a period of time with more pressure on one side being out of alignment. Have you thought about getting the alignment as close as you can and running it for a bit to see it gets any better and “re-centers”. Just something that came to my mind, may not work. Just...

    I'm doing my Bellows. Mercruiser A1G1. Are the Amazon Bellows Kits any good?

    Mercruiser parts are made to their standards. When they are copied they are made to a price point. When that happens concessions have to be made in the manufacturing process and cheaper materials are used.

    I'm doing my Bellows. Mercruiser A1G1. Are the Amazon Bellows Kits any good?

    Last fall when I changed out the bellows on one of my boats I was surprised by the condition. They were the originals from 2005 and still useable with no cracks but I figured it was time. Garage storage with the drive down seems to have been kind to the rubber components.

    I'm doing my Bellows. Mercruiser A1G1. Are the Amazon Bellows Kits any good?

    They can feel pliable, however it’s the fitment that matters. Perhaps you got luckily and found a good aftermarket kit, you’ll find out when you install. For me, the labor involved I wanted to use OEM. Numerous people have had issues with the OD tolerance of some aftermarket gimbal bearings. I...

    Snapped the dreaded Mercruiser transom Drive Lube Fitting....

    The telescoping pen magnets I have stuck fine to it. Most of the stainless fasteners used on my Sea Ray are low grade stainless and fairly magnetic.

    Snapped the dreaded Mercruiser transom Drive Lube Fitting....

    When I changed out my bellows and gear line fitting I used a long pick to remove the e-clip. For reinstallation I tied a piece of thread to it so it wouldn’t fly away trying to get it on. I used a telescoping pen magnet and put the clip on the magnet and was able to maneuver it into place and...

    4.3 milk maker

    When the plugs are removed to empty the water in the block and manifolds, you must insert a screwdriver or something similar into the holes to verify they aren’t blocked by rust and holding water.

    Harbor freight jack.

    I have a few of the Daytona jacks and nothing but good things to say. If you get any jack from HF, check the oil level. Often they’re low.

    Leak into bilge, bellows?

    Your splines on the outdrive driveshaft most likely need rotated some to mate with the coupler. With the outdrive in gear I use the prop while pushing it on and it will fall in once the driveshaft lines up.

    Here is a thread from when I did my bellows in the fall and an order I used for assembly. Post in thread 'Bellows Installation' https://forums.iboats.com/threads/bellows-installation.775185/post-5949853 I used a zip tie on the gear lube hose.

    Gen 2 water and oil hose
