    Re-painting painted aluminum boat

    Thanks for the feedback! Rattle can sounds like a plan for me.

    Mercruiser 2.5 cam shifting horizontally

    I will be dropping the block, cam, and crank off at the machine shop Tuesday. I have the cam bearings delivered and going to have them pressed in. Also, for sure the engine block distributor bushing has some pretty good wear to it. I’m going to have them check the crank and rod journals to be...

    Re-painting painted aluminum boat

    I have a 1976 Starcraft 18' I am completely restoring. I have a plan for the top surface of the bow,transom, and gunwales, but was wondering what are my options as far as painting over the original paint job? Can I run a fine grit over the existing paintjob and paint from there? If so, what are...

    Mercruiser 2.5 cam shifting horizontally

    Ok, I’ll take a peek beneath the cap. I feel it’s likely the cam bearings being the way they are is where my knock has came from, but trying to figure out where and why they went bad. As one mentioned, looks like they may have been improperly installed. Hoping I have caught this early on because...

    Mercruiser 2.5 cam shifting horizontally

    I finished up with work for the day and looked over the distributor shaft. I do see some wear and tear along the shaft and looks the same at the area the shaft drops in through the block. Is this because of the bad bushing the lower part of the shaft fits through? I can get a slight rocking...

    Mercruiser 2.5 cam shifting horizontally

    Ok, wasn’t aware of bushings along the distributor shaft. The fuel pump does use a dedicated lobe. Maybe a sign too, the fuel pump looks to be very recently replaced. I added a short clip of the motor idling and at mid range rpms. Can only imagine the walking of the cam as in the video rotating...

    Mercruiser 2.5 cam shifting horizontally

    I see no wear on timing cover. Also the timing gear in cam looks clean.

    Mercruiser 2.5 cam shifting horizontally

    Yes that was my initial thought before pulling the cam, perhaps the thrust washer wasn’t installed. But upon pulling it out, I can see the washer behind the thrust plate. There is a core plug that I’m assuming the cam end sits against, it seems to me is properly placed. Something is haywire and...

    Mercruiser 2.5 cam shifting horizontally

    I thought of that. Someone was in the block prior. The rear freeze plug had RTV around the rim of it. I wonder if someone tried pressing them in on their own.

    Mercruiser 2.5 cam shifting horizontally

    Thanks for the response. Interesting thing is the cam gear (no chain, gear driven) and crank gear are both clean with no odd wear. Same with the distributor gear and gear on the cam . I have some pictures I can post. Seems I’m having an issue with that though not sure if there is a minimum post...

    Mercruiser 2.5 cam shifting horizontally

    Recently purchased a 1981 StarCraft with a 2.5 120 hp Mercruiser. The motor had a good knock to it so ended up tearing it down. Cam bearings are exceptionally wore but also noticed the cam “rocking” back and forth. The cylinders all checked out at 160-165 psi. No visible signs of crank or rod...
