    Mercruiser Alpha 1 Gen 1 upper seal bearing pre load

    How much did you tighten it? should be like 1/8 of a turn at a time, then re-check the rolling torque. If the bearing is rusted or worn or defective, then it might lock up once it is tightened. This is how you separate them . . . It is a bearing splitter and it will wedge apart the inner...

    'In water' cooling system maintenance . . .

    Yea, it seems that with the twin engine setup, they make them really close together (like 2") . . . not sure why. Here is a picture of the starboard sea water strainer . . . and here is the port engine strainer . . . I sort of wish the starboard engine was the one that needed attention . ...

    'In water' cooling system maintenance . . .

    Structural Moisture Remediation - something I came across . . .

    I know that the topic of resolving structural moisture ( in transoms, stringers, bulkheads, foam chambers, etc) in a "pre-rot" situation comes up on this forum from time to time. I myself have raised the issue with my current boat. Conventional wisdom is to cut & gut the affected areas and...

    How do i remove trim sender bolt?

    Oh, got it . . . the trim sender wires . . . I have replaced the senders/wires without removing the bell housing, but it is better to remove the outdrive. If you want to try it with the outdrive on . . . 1/4" socket with 2 6" extensions and a u-joint adapter. 7/16" socket as stated. You would...

    Formula 330 SS Head Liner Refubishment

    Update: With the extra headliner fabric, I got some 1" foam backing and did the back wall of the cabin. It came out OK, not perfect, but OK. I had to do it in 3 sections to surround the cabin hatch, whereas the factory makes it one full piece.

    Too much Seafoam in motor oil ?

    OK, I went to change the oil on the Mercruiser 7.4's this weekend, and had some extra Seafoam. So, I added a can (16 oz) to each engine before the oil change and ran them through a 30 minute warmup, then pumped out the oil. To my surprise the oil came out foamy. So, initial thought was "oh...

    Bravo 3 Bellows Replacement - Times 2

    Thanks, having taken the bellows off, the top mark does put the flat spots at the sides. My old ones were just installed about 45 degrees off from being correct. It did not seem to have anything to do with the chaffing however. Another thing I noticed is that with the proper orientation, the...

    Bravo 3 Bellows Replacement - Times 2

    I used my ankle grinder with wire brush attachment to clean up the bell housing a bit and take off the corner that was causing the chaffing. I painted the bell housing in the areas where I ground off some corrosion . . . The Starboard bell housing was much worse than the port housing in...

    Bravo 3 Bellows Replacement - Times 2

    Well, I started into the bellows on both outdrives today first the drives had to come off, and the trim limit and sender get taped up out f the way. I was thinking the hings pins would be nearly impossible to remove, but with the help if a long handle wrench, I was able to break them loose...

    1969 Mercury 7.5 HP Drive Shaft . . . .

    I launched the boat today. . . everything worked out fine. Here are a couple of pics . . . The steering is still really stiff. So, that may require a full dis-assembly of the clamp/swivel bracket. The water 'pee' stream stayed healthy the whole time, which is a good thing . . . reaming...

    1969 Mercury 7.5 HP Drive Shaft . . . .

    I put a heat gun on the area of the pivot shaft to loosen things up a bit . . . some improvement, but still a bit still, which is fine for steering. I mounted the engine to the dinghy in preparation for launching tomorrow. I got to wait for the time to be right in order to launch from my back...

    Bravo 3 Bellows Replacement - Times 2

    As I prepped my boat for seasonal launching I noticed that the u-joint bellows are showing signs of wear from chaffing along several ridges of the bellows. At least from what I can see with the outdrive tilted up. I have not known chaffing to be an issue, at least based on my previous Bravo...

    1969 Mercury 7.5 HP Drive Shaft . . . .

    I got the engine all back together and gave it a test run today. Seems to be OK . . . One additional thing that I did was to enlarge the 'pee hole' (by drilling it out to a larger size), as it would continually get clogged. Now it seems to be fine and can pass bit of crud fairly easily...
