    White Smoke on First Start on Muffs

    First start on muffs of the season. I was unavailable between the time of haul out and harbor shrinkwrap so had boat winterized by a mechanic prior to winter storage. The starboard engine started up easily. I noted that there was more white smoke coming out of the exhaust. When I pulled the...

    Removing Shift Assist

    I removed the shift assist from both drives. Should I do anything about the extra space on the studs? Note that I had to shim up various touch points on the upper control cable due to excessive play. I plan to replace the cable asap.

    Has anyone ever used nylon lower shift shaft bushings? https://www.amazon.com/Replacement-Mercruiser-23-30617A2-Generation-1972-1990/dp/B0752ZBSK9/

    Alpha 1 Gen 1 - Teardown - Need Advice

    That's what I was thinking based on my understanding of the seals in place. The shaft looks like it's been minimally corroded already but not catastrophically so. Definitely interesting spectrum of responses here! That makes sense. I can imagine without it the groove could catch the seal and...

    Alpha 1 Gen 1 - Teardown - Need Advice

    Should I worry about replacing the shift shaft bushing and seal on the lower unit? It's not totally clear what parts are necessary. From the following part stack (from https://www.mercruiserparts.com/bam/subassembly/30870/2203/110): I'm thinking: 47 - reuse 48 -...

    Alpha 1 Gen 1 - Teardown - Need Advice

    Thanks all for the input. I've ordered parts and will hope for good weather to get the boat in the water next week. I completely agree that it is not a lot of time to pull the drives and replace the seals and water pump housings. The impeller kit I contained an o-ring that fit the shaft. I put...

    Alpha 1 Gen 1 - Teardown - Need Advice

    I haven't replaced the water pump bases. There was some wear on the water pump bases and some evidence of overheating but did not look severe. If I had parts on hand, I would have replaced the bases and waterpump housings. The impellers were replaced though the old ones looked ok. I'm assuming...

    Damaged corner of swim platform - how to repair?

    Thanks. On further inspection, there are many signs of rot in the swim platform - most likely from the davit screws that may not have been sealed properly. The swim platform is integrated into the hull and there is a soft spot on the port corner (not the corner with the damage). Has anyone ever...

    Alpha 1 Gen 1 - Teardown - Need Advice

    Thanks for the info. I finished replacing the impeller, shift cables, and upper shift shaft bushings and installing the missing welch plug. I replaced the corroded nut and washer as well. Everything went pretty smoothly in reassembly and the drives are back on the stern. I did note that the...

    It looks like it could be a YakAttack that disintegrated over time?

    Missing Grommet for Depth Finder Through Hull

    I just noticed that the through hull hole for the depth finder is missing a grommet/seal. Is there a suitable replacement given the hole pattern?

    Damaged corner of swim platform - how to repair?

    Spring lines were not sized correctly and the boat drifted into the dock over some period of time. A corner of the swim platform was damaged. In the last few days, the corner started getting wet. What would be reasonable course for repair and prevent any rot? Thanks

    Alpha 1 Gen 1 - Teardown - Need Advice

    Hi all, First time doing work on the outdrive and noticed a few things that I'd like to get advice on. The boat is a 1987 with dual sterndrive (Carver Santego 30). I haven't a clue on the service history. The engines run great but was very hard to get into gear last year. I'm getting a bit low...
